Amu Bukhara Irrigation System Rehabilitation Feasibility Study – Supplemental Report
I. SUMMARY
A. Background
1. The Final Report for the project preparatory technical assistance (PPTA 7917) for the proposed Amu Bukhara Irrigation System (ABIS) Rehabilitation Project was prepared by Lahmeyer International in association with InfoCapital Group and submitted to the Asian Development Bank (ADB) in March 2013. The PPTA prepared a feasibility study for the works to be financed under the investment project, and bid designs and documents for the first turnkey contract for one of the main pump stations to be modernized.
2. This Supplemental Report was prepared based on an increased scope of work for the PPTA in order to conduct tasks necessary to address requested revisions to the design of the Khamza New Pump Station.
3. The Khamza 1 Pump Station (64 m3/s) was prioritized during the PPTA because as the first main pump station in the ABIS it was originally commissioned in 1965 and has exceeded its design service life. In addition, a seismic stability investigation conducted during the PPTA found that the main pump building of the Khamza 1 Pump Station requires replacement.1 As a result during the PPTA a pump station design was prepared – termed the “Khamza New Pump Station” – that combined both existing plants with a combined design discharge capacity of 105 m3/s for an estimated cost of $140 million. Criteria for the design of the pump station were established during the Inception Phase and refined subsequently in direct discussions between ADB, MAWR, the UZSUVLOYIHA Design Institute, and the PPTA Consultant.
4. During the ADB Loan Fact Finding mission in March 2013 and in the ToR for the Supplemental Works, ADB and MAWR requested the PPTA Consultant to revise the design of the Khamza New Pump Station based on (i) a lower design discharge capacity, (ii) a 6 kV power supply to be compatible with the existing power sub-station, (iii) not combining the auxiliary pump station into the design, and (iv) applying other updated design criteria as summarized in the following section. The full set of updated design criteria are included in the Protocol in Appendix 1.
5. Consequently, the design, drawings, cost estimates and bidding documents for the Khamza New Pump Station were revised and updated as summarized in this Supplemental Report.
B. Scope of Supplemental Design Works
6. The scope of work for the supplemental design included:
Development of updated design criteria and approval by MAWR Preparation of three (3) preliminary design alternatives with cost estimations for different motor and pump set options

Preparation of the feasibility-level design for MAWR’s selected alternative Updating of the economic and financial analysis Updating of the Supply-Design-Install bidding documents
7. Design and engineering work related to the following are not included in this supplemental addendum: (i) the existing 6.6 kV power sub-station(s) or high voltage transmission lines; (ii) updating of the ADB social and environmental safeguards in the feasibility study, although the revised pump station design does not change substantially any of the previously assigned categories or conclusions regarding environmental impacts, resettlement, and land acquisition; and (iii) other ABIS main pump stations or sub-components in the proposed rehabilitation project.
II. UPDATED DESIGN CRITERIA
A. Design Criteria
8. A meeting was held in Tashkent on 5 June 2013 between the MAWR and PPTA Consultant to develop the approved design criteria for the Khamza New Pump Station. A copy of the signed Protocol endorsed by the Deputy Minister of the MAWR presenting the updated design criteria is included as Appendix 1.
9. Among other things, the updated design criteria include the following:
Design discharge capacity: 80 m3/s Power supply voltage: 6.6 kV Service area (net irrigated area): 72,000 ha Other requirements (eg, location/layout, pump type, auxiliary systems, building type, control system, etc.): same as Final Feasibility Study Report
10. Due to the reduction in design discharge capacity and the requirement of using a 6.6 kV power supply, several design parameters of the pump station were affected including (i) the minimum number of main pumps and stand-by pumps, (ii) the sizes and capacities of various auxiliary system components, (iii) the pump speed, (iv) the size and configuration of the switchgear, motors, and electrical power supply components, (v) the capacity of the new intake channel and discharge basin, (vi) diameter and configuration of the discharge pipelines, and (vii) the dimensions and layout of the main pump building and quantities of associated civil works.
11. The design of the Khamza New Pump Station as presented in the Final Feasibility Study Report included the replacement of the auxiliary pump station, which was built in 1981 adjacent to the existing Khamza 1 Pump Station. The updated design criteria do not include combining the capacity or operational functionality of the auxiliary pump station. As noted in the assessment report contained in Appendix 4 of Annex 2 of the Final Report, there has been significant deterioration to the electro-mechanical and electrical equipment at the auxiliary pump station, which previous deficiency inspections have called for the replacement/repair of. At the request of the MAWR, any necessary upgrades the Khamza Auxiliary Pump Station have not been included in the supplemental design works.

B. Design Capacity and Design Flow
12. The design capacity and design flow of the pump units in the Khamza New Pump Station have been updated considering (i) the pumped discharges that have occurred during recent years (since 2006), and (ii) the estimated crop water requirements during the peak irrigation season (summer months) for the design service area and cropping pattern.
13. Per the requirements of the MAWR, pumping in recent years (2006 to 2012) by the Khamza Auxiliary Pump Station was considered in terms of examining historical pumping records in order to derive the peak pumping flow rate, together with the Khamza 1 Pump Station. However, according to the MAWR the Khamza Auxiliary Pump Station will continue to remain in service, and therefore is not being combined as part of the construction of the Khamza New Pump Station.2 This means that the design of the intake channel and other works required for the Khamza New Pump Station had to take into account the continued operation of the Khamza Auxiliary Pump Station.
14. Similarly, the operation of the Khamza 2 Pump Station was not presently considered in determining the required design capacity of the Khamza New Pump Station. It has previously been determined that at this pump station all the main pump units are continuously operated during the peak irrigation season, including the stand-by unit (refer to the Annex 2 of the Final Feasibility Study Report). If the irrigation demand in the future is such that this amount of pumping capacity is required from the Khamza 2 Pump Station, then when it is rehabilitated or re-constructed the need for additional stand-by pumps should be considered.
15. The required design capacity has been determined as 80 m3/s. This is consistent with both historical pump records and the estimated irrigation water requirements analysed in this supplemental report.
1. Peak Flow (Historical Pump Records)
16. The MAWR provided historical discharge records for the Khamza 1 and Khamza Auxiliary Pump Stations between 2006 and 2012 (refer to Appendix 2). Table 1 summarizes the pumping records in terms of the highest monthly volume (Mm3) each year and the equivalent flow rate (m 3/s). There are two irrigation seasons in Uzbekistan: vegetation, April to September; and non-vegetation, October to March. The peak pumping period occurs during the 3-month summer period from June to August, and depending on the year one of those months has the highest irrigation demand (usually July). During the 7-year period examined, the peak pumped flow rate ranged from approximately 63 to 81 m 3/s (refer to Figure 1), with an average peak flow rate of 68 m3/s. The highest average monthly flow rate of 81 m 3/s combined from both stations occurred in July 2010. Pumping from June to August represents on average about 46% of the annual pumped volume.
2 No funds have been allocated in the ABIS Rehabilitation Program for the rehabilitation/modernization of the Khamza Auxiliary Pump Station. This pump station will stay in operation only during the commissioning of the Khamza New Pump Station and then be deactivated.

17. During the non-vegetation season (October to March), the average monthly pumped volume from both stations is approximately 51 Mm3 (refer to Appendix 2), which is equivalent to a continuous pumping flow rate of about 19 m3/s. There is considerably more variability in the amount of pumping during the non-vegetation season, and the range in minimum monthly flows ranged from 9.4 to 14.6 m3/s. For design purposes the minimum required flow has been estimated as 20 m3/s.

18. Note that the discharge records provided by the MAWR are not based on accurate flow meter readings taken for each pump. Instead, the pumped flow rate is recorded on the basis of the discharge from the whole pump station as measured in a rated section (hydro-post) of the ABMK downstream of the discharge basin, and checked with pump rating curves. As discussed in the site visit assessments in the Final Feasibility Study Report, the accuracy of such records is expected to lie within a range of approximately ±10-15%.
2. Irrigation Water Requirements
19. The breakdown of the 72,000 ha design service area is shown in Table 2.

21. The calculation of crop water requirements (evapotranspiration and leaching) for the design service area of the Khamza New Pump Station (72,000 ha) was determined on the basis of ‘hydro-modules’ (pre-defined tables of irrigation requirements) where soil- meliorative conditions of the irrigated lands in the service area were estimated and updated. The published figures for irrigation requirements in each designated hydro-module are based on average climatic conditions of the particular area, soil type, depth to groundwater table, and crop water requirements. The computational techniques used by the PPTA Consultant for estimating crop water requirements are based on national standards and procedures in Uzbekistan. The hydro-modules reflect both irrigation water requirements in the vegetation and non-vegetation seasons, plus leaching irrigations done in the non- vegetation season.
22. The soil-meliorative zone maps and related information used by the PPTA Consultant were provided by the Uzsuvloyiha Design Institute in Tashkent and have been in regular use since the ABIS was constructed (refer to Figure 2) and accurately reflect the coverage of zones to be used for the determination of irrigation water requirements for the Khamza New Pump Station.
23. In the ABIS command area, there are areas represented by hydro-modules III, IV, V, VI and VII as summarized in Table 4. With the existing soil-ameliorative conditions hydro-module V represents about 62% of the districts in the Bukhara Region on average, and about 16% in the Navoi Region. In the Navoi Region, hydro-modules IV and VI predominate, representing approximately 45% and 35% on average, respectively.

24. The standard (normative) irrigation rates for each hydro-module by crop type during the vegetation and non-vegetation seasons are presented in Appendix 3. The tables include prescribed irrigation values (m3/ha) pertaining to the: (i) crop, (ii) number of irrigations, (iii) irrigation period, and (iv) leaching requirement by salinity level. These hydro-modules are the calculated irrigation norms for agricultural crops in the Amu Darya Basin as prepared by the Uzgipromeliovodkhoz Design Institute.3

25. Application of the hydro-modules coverage areas (ratios) by district in Table 4 to the irrigation norms in Appendix 3 provides the weighted average net irrigation requirements summarized in Table 5. On average the annual net irrigation water requirements in the Bukhara and Navoi Regions are approximately 8,701 m3/ha and 8,332 m3/ha, respectively. The monthly weighted average net irrigation requirements by district for each crop type are included in Appendix 4.

26. Estimates of irrigation efficiencies in the portions of the ABIS service area to be supplied by the Khamza New Pump Station were provided by the Uzsuvloyiha Design Institute. The estimated irrigation efficiencies range from 0.58 to 0.62 (refer to Table 6).

27. The estimated irrigation efficiencies have to be applied to the net irrigation water requirements (Table 5 and Appendix 4) in order to determine the pumping requirements for the design service area. On this basis the calculated annual pumping requirement for the design service area is approximately 1,031.74 Mm3, with 742.85 Mm3 of water consumption occurring in the vegetation season, and 288.89 Mm3 in the non-vegetation season. The monthly pumping requirements by district for irrigation supplies from the Khamza New Pump Station are provided in Appendix 5.

28. The estimated monthly pumping requirements for the Khamza New Pump Station are summarized in Table 7 and Figure 3. The month of July (month VII) represents the period of peak irrigation demand. Converting the irrigation water requirement in that month of 212.17 Mm3 assuming continuous pumping (24 hrs per day, 7 days per week) results in an equivalent design flow rate of approximately 79 m3/s.

III. KHAMZA NEW PUMP STATION DESIGN
A. Location and Layout
29. The new location of the proposed pump station was tentatively selected as close as possible to the existing intake canal of Khamza 1 Pump Station (the ABMK 1 section of the main conveyance canal system), which would still allow construction works for Khamza New Pump Station to occur without affecting the water supplied by the Khamza 1 and Khamza Auxiliary Pump Stations. The proposed new construction site is about 600 m from the location of Khamza 1 Pump Station (refer to Figure 4).
30. The approximate coordinates of Khamza New Pump Station location are as follows (shown in Figure 4):
East: 064 04´ North: 039 20´

32. The pump station building for Khamza New Pump Station will consist of a substructure and superstructure. The main equipment such as main pump unit sets, switchgear and auxiliary pump station equipment will be installed in the pump station building. For power supply the existing high-voltage sub-station will be upgraded with new transformers and other equipment and a new transmission line extended to the new building.
33. A closed gallery for dewatering the main pump units, in case of maintenance, and a drainage sump for collecting seepage water will be located at the lowest elevation of the building. Pump unit sets will be of vertical centrifugal type. Main electric motors will be installed at pump house elevation of El. 185.65 m asl. The centre line of the pump volute case is at El. 179.85 m asl. A pump house overhead crane for installation, dismantling and maintenance work will be installed inside the pump house. Outside of the main pump station building additional facilities will be located for the emergency diesel generators, the workshop, office rooms, rooms for pump station personnel, and an oil turbine storage area.
34. An unlined intake canal will be constructed with the design discharge of 91.5 m3/s (maximum). To enable crossing of the intake canal to reach the existing Khamza 1 Pump Station and the sub-station a new bridge will be required.
35. Khamza New Pump Station will consist of the following structures: (i) diversion canal (ii) trash screen structure (iii) forebay (iv) pumping station building with intake chambers (v) discharge pipeline system (vi) sedimentation basin for technical water supply (vii) water discharge structures (viii) discharge canal (ix) auxiliary facilities and building (x) sub-station
36. The overall dimensions of the pump building are: (i) length approx. 74.0 m (ii) width approx. 20.3 m (iii) total height approx. 24.5 m
37. The pump station building is to be made of in-situ concrete divided by an expansion joint into two blocks.
B. Pump House Mechanical Equipment
1. Components
38. The Khamza New Pump Station mechanical equipment consists of the following equipment and systems: (i) Main pump units (ii) Main and maintenance discharge shut-off valve

2. Pump Units Design Criteria
39. The design criteria for the pump units include the hydraulic pump station data, the required pump station capacity, government design guidelines, and operational aspects.
40. The Khamza New Pump Station is characterized by the following design elevations:
Intake Levels Intake sill level to pump chambers El. 180.46 m asl. Intake water levels Q = 20.0 m³/s 1) El. 184.88 m asl. Q = 50.8 m³/s 2) El. 186.48 m asl. Q = 80.0 m³/s 3) El. 187.52 m asl. Q = 91.5 m³/s 4) El. 187.85 m asl. Discharge Basin Levels Discharge basin sill level El. 224.20 m asl. Discharge canal sill level El. 226.95 m asl. Discharge basin water levels Q = 20.0 m³/s 1) El. 229.39 m asl. Q = 50.8 m³/s 2) El. 230.87 m asl. Q = 80.0 m³/s 3) El. 231.80 m asl. Q = 91.5 m³/s 4) El. 232.16 m asl.
Note: 1) Minimum discharge 2) Pump station design discharge 3) Rated pump station discharge with seven (7) pump units in operation 4) Maximum pump station discharge with eight (8) pump units in operation
41. The prevailing data for the required pump head and discharge present adequate hydraulic conditions for a vertically-installed, single suction, volute casing pump with Francis type pump impeller, which has a high efficiency.
42. The expected (high) sediment content of the diverted river water requires particular attention regarding the selection of erosion-resistant materials, or coating of components of the water passages and adequate access for the replacement or repair of eroded parts.
Lahmeyer International in association with InfoCapital Group page 14
InfoCapital Group
Amu Bukhara Irrigation System Rehabilitation Feasibility Study – Supplemental Report
Selection of Number of Pump Units:
43. The number of pumps for Khamza New Pump Station aims to obtain a size not too large and requiring huge mechanical, electrical and hydro-mechanical installations, nor too small with many pumps and higher equipment, facility, and operation and maintenance costs. Further the availability of large pumps on the world market and number of possible suppliers for competition needs to be considered. Control of the irrigation water supply is more precise with a higher number of pumps than smaller number with high capacities.
44. By comparing the different aspects and the gained experience of already installed pumps for the existing pump stations a number of pumps in operation of seven (7) would be recommended for the Khamza New Pump Station.
45. For agricultural areas where pumping availability is 80% or lower of the year, or the interval between operations is insufficient to allow proper maintenance of equipment, standby capacity equal to the largest pumping unit should be provided. For the Khamza New Pump Station the standby capacity was selected as one (1) pump unit set. This will provide sufficient reserve during high peak load during the irrigation season from July to August.
46. Total number of pump units for the Khamza New Pump Station is considered with eight (8) including one (1) standby unit.
Selection of Pump Speed and Specific Speed:
47. The pump speed and specific speed (nq = n * Q0.5 / H0.75) selection for pump units is one of major criteria for the entire pump station design.
48. The abrasive solids, solids passing capability, efficiency, suction inlet conditions (e.g. Net-Positive-Suction-Head), equipment cost, and desired reliability need to be considered for the selection of the pump speed.
49. Table 8 provides a summary of the influence of pump speed on different conditions:
Lahmeyer International in association with InfoCapital Group page 15
InfoCapital Group
Amu Bukhara Irrigation System Rehabilitation Feasibility Study – Supplemental Report
Table 8: Pump Speed and Specific Speed
CONDITION PUMP SPEED & SPECIFIC SPEED
Abrasives Lower pump speeds are better with regard to wear life for sliding abrasion. 2.5 The wear rate varies roughly as (RPM1/RPM2) factor.
Solids Passing Pump impellers with higher specific speeds nq have more openness to the
blade passages than lower nq Pumps.
-1 Efficiency Efficiency tends to increase with nq up to around 50 to 60 min and then
decrease with further increasing nq.
Cavitation Pumps with lower speeds generally have lower NPSH requirements and a wider allowable operating range than pumps with higher speeds.
Capital costs Pumps with higher speeds are physically smaller than lower speed pumps for the same duty point. Both motors and pumps are less expensive and occupy a smaller installation area.
Reliability Pumps with higher speed are less tolerant to difficult service conditions than lower speed pumps. Factors such as solids, cavitation, and off design-point operation may severely impact reliability. Any capital cost benefit may be eliminated by pre-mature equipment failure. For difficult applications, especially where high power requirement is involved, it is usually a good practice to be conservative with equipment speed.

50. For the pump units of the Khamza New Pump Station five (5) feasible pump alternatives with pump speeds from 250 to 375 min-1 were selected for further investigations. The investment costs were estimated for the pump speed alternatives considering the main pump components and the costs related to the civil works for the pump station building intake structures (refer to Table 9).

51. Alternative 3 with a pump speed of 300 min-1 would be the recommended pump speed with regard to the lowest investment costs for the pump set equipment and civil structures. Compared to the wear rate of Alternative 3, the wear rate of Alternative 4 would decrease by 20%. However, with new technologies to protect the wetted pump parts from abrasion such coatings of impellers and casings the pump units designed with a speed of 300 min -1 would still be the recommended alternative.
52. The pump specific speed has been determined with 51 min-1 using formula nq = n * Q 0.5 / H0.75; whereas Q = 11.25 m³/s, H = 53 m and n = 300 min-1 for the Khamza New pump units. The relationship between pump specific speed, pump type and hydraulic pump efficiency is shown in Figure 6. The selected pump type for Khamza New is of Francis vane with a maximum theoretical pump hydraulic efficiency of 93%.

54. The operating range of the Khamza New pump units is shown in Figure 7. The pump performance diagrams show parallel operation with system head loss curves for minimum and maximum geodetic pump heads. The parallel operation of the four identical centrifugal pumps requires the losses of individual lines (head losses up to the collecting line) to be taken into account in the reduced pump characteristic curve.

56. The expected hydraulic parameters of the pump operation are presented in Figure 8 and 9. The diagrams show the expected pump head, pump hydraulic efficiency, pump shaft power and the NPSH_req. versus the pump flow.
57. The maximum pump shaft power of 6887 kW is reached at the lowest total pump head with expected maximum pump flow of 13.5 m³/s. The pump operating range is expected between 11.25 m³/s and 13.5 m³/s. The pump hydraulic efficiency expected maximum at 91.5 % at 11.25 m³/s.
58. The maximum expected NPSH_req. of 16.2 m is at pump flow of 13.5 m³/s. With a setting height of the volute casing of 179.85 m asl. (centre line) a cavitation free operation is guaranteed over the entire operating range; but will ultimately depend on the final dimensions of the selected pump and the hydraulic design of the water passages.

229. The discharge pipe system will deliver the water from the main pump units to the discharge basin. Each main pump unit will be connected via individual discharge pipe sections with a dia. 2100/2300 mm, pipe bends, bifurcations, collector pipe and diffuser sections to the main discharge header with an inner dia. 4100 mm and length of approx. 620 m. Two (2) main discharge headers will be constructed to provide redundancy for uninterrupted water supply in case of maintenance or repair works on one of the headers.
230. Each main discharge header is connected to a siphon structure at the discharge basin as non-return installation. The siphon system will provide protection of the main pumps and preventing dewatering of the discharge canal system in an emergency case, e.g. pipe rapture. Air venting during the start phase of the main pumps to build up the vacuum and air breaking of the vacuum to avoid reverse flow when the pumps are stopped will be achieved by an aeration valve arranged on the top of each siphon. Preliminary calculations show that the siphon system will build the necessary vacuum to compensate the head loss only if 3 or 4 pumps are in operation. To insure the head recovery of the siphon in case only 1 or 2 main pumps are operating the vacuum needs to be built up by an additional vacuum pump system connected to the top of the siphon.

Pipe costs were estimated with a unit cost of 7700 US$ per ton, which reflects the costs for completed or ongoing projects in Uzbekistan of similar type and sizes. Operation and maintenance costs estimated with 1% of the investment costs. The pump costs are mainly the energy costs related to the head loss of the various main header diameters calculated. Energy costs are calculated with 6 $ct/kWh. The flow discharge was calculated on average base with 70% of the maximum pump flow through one main header pipe; e.g. 32 m³/s. The expected lifetime for the discharge pipe system is 35 years. Figure 10 shows the optimum pipe diameter for Khamza New discharge main header. The maximum flow velocity is calculated to 3.53 m/s with four (4) pump units in operation at minimum geodetic pump head.

F. Geotechnical Investigation
1. Introduction
399. The geotechnical investigation report prepared by the Uzsuvloyiha Design Institute as part of this feasibility study is included as Appendix 6.
400. Additional information on geotechnical investigations for the construction of the Khamza New Pump Station is also available from the following previously prepared investigation reports: In 1980 the Uzsuvloyiha Design Institute has implemented geotechnical investigations for Detailed Design of Khamza Auxiliary Pump Station in Bukhara region. In 1984 the Institute has implemented geotechnical investigations for Detailed Design of drainage construction to divert ground waters away from existing Khamza 1 Pump Station area.
401. This information is used as the basis for further geotechnical investigations and assessments of the conditions for the proposed Khamza New Pump Station.

Amu Bukhara Irrigation System Rehabilitation Feasibility Study – Supplemental Report
2. Geotechnical Conditions
402. The proposed site for the pump station is located at the western slope of Karakul plateau. The plateau consists of deposits formed in Neocene age, covered by Aeolian sands with a thickness from 0.5 to 4-5 m. Deposits of Neocene age are presented by weak sandstones with frequent interlayers and lenses of moderately stronger sandstones and siltstones with a thickness ranging between 0.1 m and 0.5 m.
403. Gypsum content in the soils is to 1.1% of the air-dry soil.
404. According to the operation manual of the existing Khamza 1 Pump Station, the elevation of ground water level is 190.5 m (as per 2012). Water is saline, with dissolved salts of sodium chloride and sulfate chloride (8.8-9.4 g/l).
405. The content of anions of SO4 is 3168 mg/l, HCO3 = 2.8 mg/eqv.
406. Water is aggressive to Portland cement as per standard, GOST 10178-76. Therefore, it is suggested to use the sulphate-resisting cement as per recommendations of the local standard.
407. Weak sandstone will be the base/sub-soil beneath the foundation of the pump station. Therefore, it is required to confirm this during the detailed geotechnical investigation and design the foundation accordingly to consider the properties and bearing capacity of the existing subsoil.
3 408. The density/unit weight (dry) of sandstone is 2.67-2.70 tons/m . The submerged (with natural moisture) density/unit weight of sandstone is 1.59-2.0 tons/m3, while only the skeleton’s unit weight is 1.57-1.83 tons/m 3.
409. Unit weight of loose sandstone (with structural damage) is 1.25-1.30 tons/m3, and under compacted condition is 1.39-1.45 tons/m 3. Sandstone filtration coefficient is 3- 5 m/day. Nominal design pressure is 3 kg/cm2.
410. The present report does not include any test results for the physical and mechanical properties of the subsoil including the bearing capacity of subsoil beneath the foundation. Therefore, during the detailed design stage further detailed geotechnical investigations of the project site will be required. The final design of structure and its foundation will be based on the properties of subsoil and the recommendations included in the final geotechnical report.
3. Seismic Condition
411. The proposed project site is located in a seismic zone. The seismicity of the proposed project site of the Khamza New Pump Station is assessed at 8 points (in accordance with K K 2.01.03-96), which can be confirmed during the detailed design of the project.
412. The category of sub-soil beneath footing is Class III with respect to seismic properties of the subsoil and shall be verified during the detailed geotechnical investigation of the site.
Lahmeyer International in association with InfoCapital Group page 61

Amu Bukhara Irrigation System Rehabilitation Feasibility Study – Supplemental Report
413. The feasibility study level design of the building and foundations of the pumping station is according to the local seismic code “KMK 2.01.03-96” of the country.
414. The design should be verified during the detailed design phase. It is recommended to perform 3-D nonlinear structural analysis and design of the pumping station building as required by the seismic code during the detailed design phase.
G. Topography
1. Introduction
415. Information from the topographical survey conducted by the Uzsuvloyiha Design Institute as part of this feasibility study is included as Appendix 7.
416. The proposed project area of Khamza New Pump Station is located in the Alat District of Bukhara Province. The significant part of the territory is occupied with desert pasture. The Bukhara Province is located within coordinates of 39° 48’ N and 69° 10’ E.
417. The District of Alat is located on the west of Bukhara Province, bordered with Turkmenistan and is about 430 km southwest of Tashkent. The area is sharply characterized by continental climatic conditions, prolonged hot, dry summers with short periods of precipitation.
418. The proposed Khamza New Pump Station is to replace the existing Khamza 1 Pump Station and Khamza Auxiliary Pump Station. The existing Khamza 1 Pump Station is located at PK 501+00, on a part of Amu-Bukhara canal (ABMK). The building of existing Khamza 1 Pump Station was built and constructed in 1965. The water intake into Amu-Bukhara pumping canal is from the right side of Amu Darya River in the territory of Turkmenistan. The canal traverses from west to east direction and Khamza 1 Pump Station along with Khamza Auxiliary Pump Station is the first pump station on Amu-Bukhara Canal in the cascade of other pumping stations.
419. The proposed Khamza New Pump Station is located about 300 to 600 m from Khamza 1 and Khamza Auxiliary Pump Station on the southwest side.
2. Topographic Survey
420. The Design Institute conducted a survey of Khamza New Pump Station in February 2013 (refer to Appendix 7). The survey consists of an area survey for the site of proposed building of pump station and a line survey along the center line of the traverse from the intake to the outlet.
421. The area survey is on a total area of about 400 m x 300 m and it shows the existing features and the spot elevations of the ground. The spot elevations are shown with reference to a permanent benchmark (Rp-6-13g, elevation 205.762). A total of seven (7) available permanent benchmarks are marked and shown on other sheet with their elevations.
422. A line survey along the center line of the traverse of proposed intake channel and discharge channel along with the building is accomplished comprising the cross sections at a longitudinal interval of 100 m and up to 40 m at each transverse side of center line.
Lahmeyer International in association with InfoCapital Group page 62
InfoCapital Group
Amu Bukhara Irrigation System Rehabilitation Feasibility Study – Supplemental Report
423. It is recommended to do a detailed area survey of the site before detailed design is undertaken including the area from the start of intake channel to the end of outlet channel. The detailed survey should show the complete topography of the area including the contours, elevations, existing features, the coordinates and any additional cross sections as required for the detailed design.
H. Summary Cost Estimate
424. Based on the preliminary design (feasibility level) of the Khamza New Pump Station respective costs were estimated individually for the following equipment, namely all civil structures, building services, hydraulic steel structures, mechanical equipment, electrical equipment, and instrumentation and control equipment.
425. The Cost Estimation is based on “Ex Works” World market. Shipment, loading, unloading, decommissioning and recycling of equipment, installation, testing and commissioning costs were added to the “Ex Works” Costs, considering the project location and the prevailing environmental conditions.
426. A total of ten percent (10%) was considered for mechanical and electrical works and seven percent (7%) for civil works as contingencies for unforeseen events or works, respectively.
427. Considering the above conditions; the summarized costs for the proposed construction of the Khamza New Pump Station were estimated at $100.3 million as shown in Table 12. The detailed cost estimate breakdown is included in Appendix 8.

IV. UPDATED ECONOMIC AND FINANCIAL ANALYSIS
A. Background to Supplemental Study and Analyses
428. During the PPTA period there was continuous uncertainty regarding the availability of loan funds and the extent to which the Government would be willing to contribute towards real investment. Whilst it was clear which six pump stations should be replaced/rehabilitated it was, nevertheless, unclear what other supporting sub-projects should be considered and how much should be invested in these. Given no investment target, to complete the Study on schedule, the Consultants were obliged to submit an investment package which covered the replacement/repair of all the pump stations and a small number of relatively low-cost supporting sub-projects. Even prior to Study completion, it was becoming increasingly obvious that loan funds were very tight and that Government was not going to contribute any meaningful counterpart funding (apart from paying financing charges).
429. Despite the obvious lack of funding sources, the Government continued to insist that all its desired investments should be funded from external sources and to reduce the capital costs, made a belated request to design a reduced pumping capacity Khamza 1 Pump Station. This task was undertaken and overall costs were reduced by around $25 million (refer to the Section III- Khamza New Pump Station Design).
430. At the same time, there was some firming-up of possible external loans availability and by mid-2013, some $320 million had been identified. Given no counterpart funding, despite the Khamza 1 Pump Station savings, the loan availability was, nevertheless, far short of the $412 million (excluding price contingencies) required to cover the full investment package. To create an investment package to utilise the loan availability two further measures were taken, as follows: Approximately $86 million for discharge pipes was removed from the loan package and assumed would be paid by Government over a 7 year period, under its O&M budget. Some pumps in both Kizil Tepa Main and Kizil Tepa Auxiliary Pump Stations were excluded from the investment package, thus reducing the ‘with-project’ pumping capacities of these pump stations.
B. Approach to the Analysis
431. The main task was to re-assess the economic viability of the reduced cost investment package, based on revised estimates for the five (5) relevant pump stations, which were recalculated based on the above discussion. The revised detailed cost breakdowns for those pumps stations are included in Appendix 9.
432. Further reductions were introduced through the application of some lower physical contingency factors than those recommended in the PPTA Final Report. Whilst these lower rates were approved by ADB, the Consultants wish to record their opinion that they believe that their original estimates were realistic, given the high levels of uncertainty involved when installing pumps, motors and modernised support systems into operational pump stations.
Lahmeyer International in association with InfoCapital Group page 64
InfoCapital Group
Amu Bukhara Irrigation System Rehabilitation Feasibility Study – Supplemental Report
433. A number of other assumptions used in the PPTA Final Report were also changed, as a consequence of ADB directives. Of these the significant changes were as follows :
Electricity price was set at UZS 112.2/kwh or $0.53/kW-hr (using the official exchange rate) compared to $0.75/kW-hr in the original base case analysis. If the real exchange rate were to be applied the current UZS price would be equivalent to $0.4/kW-hr. Decline scenarios. ADB suggested that possibly using differing annual decline rate assumptions (for example 1%, 2%, 4% and 5%), possibly changing over time, and starting at different times, might be appropriate. Although other changes were discussed, following confirmation from ADB, in the final analysis no alterations were made to the cost of cotton-picking labour and no increases were made to ‘with-project’ crop productivity. The question of exchange rates remains in limbo. The Consultant does not believe it is appropriate to use the official $/UZB exchange rate in the economic analysis.
434. A similar approach to that taken when preparing the PPTA Final Report analyses was adopted, and each of the supporting tables which featured in the first analysis have been utilised in the latest analyses, with changes made where appropriate.
C. Analysis Results
435. With decreased capital costs of around 16% (having accounted for the extra maintenance cost transferred to Government to cover the repair/replacement of discharge pipes serving four pump stations), with decreased ‘with-project’ net benefits of around 9%, (resulting from the 24,400 ha in the service area of the Kizil Tepa Pump Station and its Auxiliary which would no longer receive irrigation water) and with similar unit energy costs, the EIRRs for the Reduced Cost Options (with pump decline and with pump failure) are quite similar to those obtained for the Full Cost Options presented in the PPTA Final Report. The results of the base case analyses and a range of sensitivity analyses are presented in Table 13.
436. Given the challenges in predicting a future ‘without-project’ situation, it is suggested that it is reasonable to consider that the base case EIRR lies between 12% and 18%.
437. There are, however, a number of issues which could arise and which could result in poorer returns. Ironically, for example, if the ABIS mechanics were able to continue keeping the aging pumps in working order, as they have done up to now, the ‘without- project’ crop returns would decline less rapidly, the ‘with-project’ benefits would be reduced, and the economic viability would become less favourable. Sensitivities, reflecting this possible situation, through reducing the assumed annual decline rates in pumping capability and through delaying the onset of decline, were carried out and the significant negative impacts these have are evident from the results presented above.

Table 13: Base Case and Sensitivity Analysis – EIRR % Case Gradual Pump Total Pump Decline Scenario Failure (base case) Scenario Base Case 12.2 18.4 Electricity price : - US$ 0.075/kwh 11 16.5 - US$ 0.100/kwh 9.4 13.9 Capital costs : - Increased to 110% 10.7 17.5 - Increased to 120% 9.4 16.6 Cotton price : - Increased to 110% 13.3 19.7 - Decreased to 90% 11 16.9 Pump capacity decline rate: - Reduced from 5% to 3% 7 na Onset of first year of decline - Advanced by 1 year 11.1 na - Advanced by 2 years 9.9 na - Advanced by 3 years 8.6 na na = not applicable.
438. Two other significant factors could negatively impact on the economic viability of this Reduced Cost Option.
439. Contingencies have been cut significantly; in reality this could result in further funds having to be found from Government resources to make good future shortfalls. Capital costs would thus increase and the EIRR would fall. Alternatively, corners could be cut with the likely impact that the system would not operate as efficiently as it was originally designed to do, resulting in either increased O&M costs or reduced pumping capacity leading to reduced ‘with-project’ irrigation, or both.
440. The shifting of financing for the construction/repair of the discharge pipes in four out of the five pump stations, from being a loan to being a Government responsibility also threatens potentially negative impacts. The Government was unable to offer any significant counterpart funding and yet is now facing the prospect of having to allocate over $80 million of additional O&M funding. The possibility for inadequate provision and the breakdown of these pipes is one of serious concern. If, has already been the experience, there are major pipe bursts, the consequences could be catastrophic, in terms of destruction of pumping facilities located at the base of the pipes, of loss of human lives, and, if repairs cannot be implemented rapidly, of major irrigation failure.
441. Whilst the above issues weigh against the economic viability of the proposed Reduced Cost Option being highly favourable, it should also be borne in mind that the ABIS system provides or supplements supplies of DMI water to a large number of towns and communities in the ABIS area. The benefits which would result from safeguarding these supplies have not been included; they are considered to be very significant.
Lahmeyer International in association with InfoCapital Group page 66

Amu Bukhara Irrigation System Rehabilitation Feasibility Study – Supplemental Report
442. Consideration should also be given to the fact that other investments in the ABIS system have recently been or are still being made. If the main pump stations of concern to the proposed Project were not replaced or rehabilitated, these other investments would be wasted. These include the Navoi Pump Station, which is part of the Kizil Tepa irrigation system, the replacement of the Kuyu Mazar Floating Pump Station, which works in conjunction with the main Kuyu Mazar Pump Station, and the on-going Land Amelioration and Drainage Projects.

Amu Bukhara Irrigation System Rehabilitation Feasibility Study – Supplemental Report
V. ECONOMIC AND FINANCIAL ANALYSIS (LINKED DOCUMENT FOR RRP 44458)
A. Approach and Methodology
446. The economic and financial analyses prepared assumed that all subprojects which had been recommended for implementation would be included in the project cost; due to budgetary constraints, however, it was necessary to scale down the level of the originally proposed investment. The main subprojects comprised five pump stations (PS) (Khamza New, Khamza 2, Kuyu Mazar, Kizil Tepa (partial) and Kizil Tepa Auxiliary (partial)). It was also necessary to reclassify the costs of replacing the discharge pipes in all but the Khamza New PS from a loan to a maintenance cost, to be borne by the Uzbekistan Government. Other subprojects included the Amu Bukhara Main Canal (ABMC) rehabilitation subproject, the decision support system (DSS) and supervisory control and data acquisition (SCADA) subproject and the Climate Change Adaptation and Demonstration Farms subproject. Management and implementation supporting activities were also included. The main economic benefit of the Project would be to maintain existing levels of agricultural production in most parts of the Project Area and to limit the extent of decline which would ensue if the existing pumps are not replaced. With improved pump-set efficiencies there would also be substantial energy savings. Project investment is focused on three irrigation schemes, covering around 250,000 hectares (ha), which lie within the overall ABIS area of 315,000 ha.
B. Key Assumptions
447. All investments and benefits have been valued at late 2012 prices. For traded commodities, such as cotton, fertilizers, and wheat, border parity prices, based on World Bank Commodity price projections, were prepared. For non-traded commodities, all prices were based on current market prices. A shadow value of 0.8 was applied to normal agricultural wage rates, but not to that used for cotton harvesting where it is becoming increasingly difficult to find sufficient labor. A markup of 20% was applied in the economic analysis to standard farm machinery rental charges, which are considered to be rather low and generally under-reflective of the costs of replacement. A standard conversion factor of 0.8 was applied to the local currency portion of capital costs. The current price for power at SUM 112.2/kW-hr, was applied in the base case economic analysis.
C. Project Benefits
448. This Project is focused primarily on sustainable and reliable water supplies and is unlikely to make any significant contribution towards improved cropping productivity. Project benefits will be derived from (i) the avoidance of the crop losses which would be incurred if the existing pump stations are not replaced or rehabilitated, (ii) some improvement in water conveyance efficiencies resulting from the rehabilitation of the ABMC structures and improved system management which will be facilitated through the DSS and SCADA interventions, and (iii) the reduced power consumption of the higher– efficiency pump sets.

Amu Bukhara Irrigation System Rehabilitation Feasibility Study – Supplemental Report
449. Future Without Project. All the large pumps within the pump stations of concern to this study are between 38 and 48 years old. Assessment reports generally indicate that all are in either worn or in critical condition, but with skilled and innovative maintenance they continue to operate. Despite the occasional pump and discharge pipe breakdown and periods when insufficient water flows from the Amu Darya, the Amu Bukhara Irrigation System (ABIS) scheme continues to be irrigated. Nevertheless, two scenarios have been identified to represent the alternative options of future system decline. The more conservative scenario assumes as a base case that within a few years, depending on the current age of the pumps, there will be a slow annual decline in pumping hours. In the base case it is assumed that the 1965 constructed Khamza 1 and Kuyu Mazar PS pumps would start declining in Year 4, the increasingly heavily used Khamza 2 PS pumps in Year 6 and the two less worn Kizil Tepa PS pumps in Year 7. Sensitivity analyses, where the decline onset period is extended, were undertaken. The more pessimistic scenario assumes that the pumps within a given pump station will totally fail over a four year period. Differing dates when the breakdowns within a given pump station will commence have been assumed according to pump age and use. The consequences of reductions in pumping capacity in terms of areas irrigated were calculated and schedules of declining net farm income prepared up to Year 25.
450. Future With Project. Following replacement or rehabilitation of the pump stations it is assumed that present cropping and cropping intensities can be maintained at current levels for the main part of the Project Area. Inevitably, where only some of the pumps will be replaced, part of the command area currently served by the two Kizil Tepa PS will not be served. Two on-going land drainage programs are currently being implemented, the benefits of which should manifest in the near future and should impact beneficially on the ‘with’ (WP) and ‘without-project’ (WOP) situations. Hence, no project- induced improvements in cropping productivity have been considered in this analysis. Once the new pumps begin operating, it is assumed that there will be substantial energy savings. Maintenance costs will, however, be considerably higher as the new machinery will be much more complex and less tolerant of the less sophisticated maintenance practices currently applied. It is also anticipated that with improved pump reliability, improved main canal structures and the provision of management facilities, there should be some saving in the total amount of water required to irrigate the scheme.
D. Financial Analysis
451. Study Area. The total area of the ABIS is approximately 315,000 ha. Development activities funded under the proposed Project are likely to have an impact on approximately 225,000 ha within three irrigation schemes as follows:
(i) Karaul Bazar – approximately 16,000 ha within Bukhara Region, (ii) Kuyu Mazar – approximately 91,000 ha within Bukhara Region, and (iii) Kizil Tepa – approximately 119,000 ha within Bukhara and Navoi Regions.
452. Crops and cropping intensities. A wide range of crops are grown with state- controlled cotton and wheat representing approximately 39% and 26% of the total cropped area respectively. Approximately half the wheat area, after harvest, is used to grow short-term ‘secondary’ crops, and virtually all the non-wheat land which is not occupied by cotton or perennial crops is also used to grow crops of the farmers’ choice.
Lahmeyer International in association with InfoCapital Group page 70
InfoCapital Group
Amu Bukhara Irrigation System Rehabilitation Feasibility Study – Supplemental Report
For the overall ABIS approximately 10% of the irrigated area is covered by perennial crops (grapes, mulberry, and other fruit). Overall cropping intensity is approximately 108%.
453. Cropping patterns and intensities vary between the schemes within ABIS. If account is taken of the detailed crop breakdowns of ‘secondary’ crops and of the large area described as ‘homestead’, vegetables occupy approximately 18% of the overall cropped area.4 Fodder crops,5 lucerne, and maize silage, occupy approximately 16% of the cropped area.
454. Crop yields. The yields of seed cotton (approximately 3.2 tons/ha) and wheat (approximately 6.0 tons/ha) in the Bukhara Region are among the highest yielding cotton in the country. This indicates that the natural soil fertility levels are better than the official classification might suggest and it is possible that the average wheat yield understates the actual yield. For vegetables, fruit and fodder, yield levels appeared to be similar to those achieved in other areas of the country.
455. Salinity and waterlogging. Care must be taken to distinguish between those areas where no significant salinity, water-logging or water shortage constraints exist and those which have such problems. In general terms about 12% of the total area is classified as having unsatisfactory cropping potential due to salinity, high groundwater, or water shortage. Interventions under Loan 2245/2246-UZB Land Improvement Project6 and the Government funded Amelioration Programme are being implemented and these should soon be having an impact, in both the ‘with’ and ‘without-project’ situations. The impact has been incorporated in the analysis in terms of the reduction in the percentage of cropped area which is affected by poor growing conditions. In the near future this is anticipated to decrease to around 5%.
456. Crop budgets in financial and economic terms were prepared for wheat, cotton, cucumbers, maize silage and mature peaches. The latter three crops were selected as representatives of their crop category after having calculated the returns for a range of the main crops within each crop category, and weighting them according to cropped area. Table 14 summarizes the estimated financial returns per hectare for normal and marginal lands.

457. The crop budgets which are presented in detail in the Financial and Economic Annex of the PPTA Final Report, provide details of inputs used and unit costs and values. Cotton and wheat production are heavily mechanized, except in regard to the cotton harvest, which is usually performed manually. No costs for the government provided irrigation water have been included, as this is free of charge to the farmer. The economic costs of water are included elsewhere in the analysis. Land is allocated free of charge to farmers, and in the most part is not owned by the farmer.
458. Whilst financial returns to cotton and wheat are rather low it should be borne in mind that the water and land are provided at no cost to the farmer, that mechanization facilities are provided at subsidized rates and the farmer is given the opportunity to utilize approximately one third of the land to grow crops of his own choice. Returns from the main crops of vegetables and fruit appear to be very attractive. Whilst in the analysis a financial value has been placed on fodder, in reality most of these crops are consumed by the farmers’ own livestock; large numbers of sheep, goats and cattle are found in the area.
459. The net economic returns per hectare of cotton are considerably higher than the financial returns, reflecting the fact that Government purchases all the cotton at prices 7 which it determines. For wheat and the other crops, the differences between the financial and economic returns are relatively small.
460. Farm size. It is estimated that there are approximately 2,570 micro-farms (smaller than 50 ha); 1,100 small farms (50 ha to 100 ha); and up to 25 large farms (exceeding 100 ha) in the Study Area. Average farm size is thus around 67 ha. For analysis purposes, it has been assumed that three typical farm sizes would be 50 ha, 100 ha and 200 ha. The number of farms has reduced dramatically over recent years. In 2007 there were over 15,000 holdings in Bukhara Region, and currently there are fewer than 4,000.
461. ‘Without-project’ irrigation scheme specific scenarios. For most farms in the Karakul Bazar irrigation scheme, the 16,000 ha scheme which gets first call on the water being pumped from the Khamza 1and Khamza 2 pump stations, it is likely that it will be many years before their supplies will be reduced. The Stage 2 pumps supplying this area are in good condition, and their replacement is not envisaged under this project. For individual farms within the Kuyu Mazar and Kizil Tepa irrigation schemes, the impact will depend on how the declining water volume is allocated between the two schemes, the rate at which the Stage 2 pumps deteriorate and the location of the farm. It is likely that farms located near the heads of the main canals feeding the irrigation areas, in Kizil Tepa, Vobkent, Gidjuvan, Kagan and Bukhara districts will be least impacted whilst those in the more remote districts will be the most severely impacted. Whilst it is envisaged that there would be attempts to spread the water, the realistic scenario is one where the tail- end farms would cease to function and the problem would gradually spread up-stream towards the main irrigation canal outlets as the water supplies diminish. With so little rainfall, the opportunities for farmers to adjust their cropping patterns in the face of declining irrigation supplies are virtually nil. With the assumptions applied, in the total failure scenario, all cropping would cease by around year 11. With the gradual decline scenario approximately 20% of the area would remain productive up to and beyond Year 25. Whatever scenario were to apply in reality for those farmers who, in the ‘without-

Amu Bukhara Irrigation System Rehabilitation Feasibility Study – Supplemental Report project’ condition lose their water supply, the impact of the Project would be to save them from total loss. The annual benefit gained would not only be the value of the crop saved, but also the safeguarding of any investments such as those made in perennial crop establishment, in land improvement, and in farm-level irrigation and on-farm access infrastructure improvement.
462. Returns per average farmed hectare. The likely average return per hectare for lands cropped in the three Study Area irrigation schemes is given in Table 15. It is assumed that by the time the Project commences, approximately 95% of the irrigated area will be capable of producing good crops and around 5% of the area will be of marginal productivity. Although there are some differences in cropping patterns between irrigation schemes, the calculations indicate that average returns/ha are very similar and average out at around SUM1,370,000 per hectare (around $500/ha at market exchange rates).

463. Net Farm Returns. No differences in cropping patterns between holding sizes have been incorporated in the analysis and the net annual returns for the three selected indicator holding sizes are presented in Table 16 below. The data presented apply to both the ‘with’ and ‘without-project’ situations as no changes in the current cropping patterns or productivity are assumed in the ‘with-project’ condition. Farms will operate similarly until the water fails to reach the farm, at which point all production will cease. Experiences on individual farms will naturally vary, depending on the rate in decline of water supply. Once the supply starts to decline it is anticipated complete farm failure would ensue over a short period.

464. Labour use. Despite the heavy mechanization, because of the nature of the crops grown there is a substantial requirement for manual labor, with a weighted average utilization per hectare for the overall cropping pattern of around 55 workdays per hectare/year, including 13 workdays used for cotton picking. A daily wage of SUM12,000 has been used for general labor and SUM15,000 (net of tax) for cotton picking. Thus average annual labor cost per cropped ha is around SUM700,000/ha. In the ‘without- project’ situation, for every hectare falling into disuse this would be the revenue lost to the local economy. On a weighted average basis the daily cost of labor is approximately SUM12,700/day.
465. Overall Financial Impact. Table 17 summarizes the anticipated overall financial impact the Reduced Cost Option investment would have over a 25 year period, based on an assumed water supply decline scenario that pumps would gradually, rather than catastrophically, fail. It indicates that over a 25 year period, the net financial farm income saved would be in the order of $1.25 billion.
466. With regard to manual labor, the total value of wages saved as a consequence of project implementation would be of the order of $636 million, or 105 million workdays.

E. Economic Analysis
467. Capital Costs. The financial base capital costs for the proposed Project were mostly computed in $ terms based on price quotations from foreign equipment suppliers. For those components which were originally derived in SUM terms, these were converted to economic values by making appropriate adjustments. A standard conversion factor was applied to the local currency portion of all components. Physical contingencies were then added and the prices converted into economic prices, as discussed previously. Cost inflation contingencies, financing charges and import duties and taxes on foreign sourced inputs were not included at this stage.
468. Most of the total capital cost is related to the construction/rehabilitation of five pump stations and associated management consultancy, whilst a remaining small portion (approximately 2.5%) of the total base cost is concerned with the rehabilitation of the main canal system and a further (less than 1%) provision of facilities to develop water saving initiatives.
469. Implementation period. In the analysis, it has been assumed that all major works would be completed during a six year implementation period. It is anticipated that the pumps would become fully operational in the seventh year after the construction program commences.
Lahmeyer International in association with InfoCapital Group page 75

Amu Bukhara Irrigation System Rehabilitation Feasibility Study – Supplemental Report
470. Recurrent Costs. Schedules were prepared for the ‘without’ and ‘with-project’ situations. Five separate elements were identified as follows
(i) Energy costs, (ii) Maintenance of Pumps and Pump Stations, (iii) Other operation and maintenance (O&M) for ABIS, excluding the above, and (iv) Periodic Pump Maintenance (in with-project situation only). (v) Rehabilitation/replacement of discharge pipes, not funded under the loan.
471. In the ‘without-project’ situation, for the one where the pumps would gradually fail to operate completely it is assumed that maintenance costs would reduce as the number of working pumps is also reduced. Where it was assumed that the pumps would gradually decline in operating capability it has been assumed that current maintenance costs would increase over time. A 5% annual increase in maintenance costs has been assumed.
472. Once the new pumps commence operating in the ‘with-project situation’, maintenance costs would rise substantially over existing levels, as a consequence of the requirement to service much more sophisticated equipment than has been the case in the past. Overall current annual non-energy O&M costs for the pump stations, are, at market exchange rates, approximately $1.2 million. For the ‘with-project’ they are anticipated to rise to around $4.5 million; exclusive of any contributions towards the capital cost of repairs and/or replacement of discharge pipes to be funded by Government.
473. In the ‘without-project’ situation there would be a reduction in Mwh used per year as the pumps become less capable of pumping, with the rate of decline depending on the assumed decline scenario. In the ‘with-project’ situation there would be an immediate reduction in power consumption once the new more efficient pumps become operational. These savings would substantially exceed the relatively small increases in additional maintenance costs. Two adjustments were made to the long term schedule of ‘with- project’ power consumption. After ten years of operation it has been assumed that there would be slight reductions in overall pump set efficiency and power consumption would consequently increase. It was also assumed that for three years, commencing in year 7, there would be an annual improvement in overall system efficiency of 1.5% resulting from several of the improvements which the Project would have introduced, including the rehabilitation of the ABMC structures and the establishment of DSS and SCADA systems. Present annual energy costs for the whole Study Area are estimated, at official exchange rates, at around $ 81 million, based on current tariffs. Once the new pumps are installed the equivalent cost should be approximately $64 million.
474. Agricultural Benefits. Apart from the energy saving benefits mentioned above, the main project benefit is that most of the area’s present status quo is maintained and most farmers would avoid the potential disaster of being deprived of all production capability. With such low rainfall, there is little prospect of farmers making a living once the irrigation supply ceases. No project derived impacts have been assumed to improve productivity beyond the levels currently being achieved, neither have any domestic, municipal, and industrial water benefits been included. The current net annual economic
Lahmeyer International in association with InfoCapital Group page 76
InfoCapital Group
Amu Bukhara Irrigation System Rehabilitation Feasibility Study – Supplemental Report value of agricultural production from the Study Area is estimated at $246 million at market exchange rates.
475. In the ’without-project’ situations, depending on the pump decline assumption, the associated declines in cropped area were estimated and by applying crop budgets (in economic prices) schedules of overall net income for the Project Area were calculated. In the ‘with-project’ situation it is assumed that the net income would remain the same as at present, once the pumps become fully operational, except in those areas currently served by pumps which would not be rehabilitated under the Project.
476. Based on the derived capital costs economic analyses were carried out and the base case results were as follows, for the two options:
(i) Where it is assumed that the Khamza pumps would totally fail by Year 11 (after project commencement), the economic internal rate of return (EIRR) was 18%, (ii) Where it is assumed that pumps would gradually decline (base case), with only 20% of the currently cropped area functioning (within the Study Area) in Year 25 after project commencement the EIRR was 12%.
477. A number of sensitivity analyses were also carried out and the results of these are presented in Table 18.

GEOTECHNICAL CONDITIONS AT KHAMZA NEW PUMP STATION
INTRODUCTION
In December 2012, the Geological Department of Uzsuvloyiha Design Institute has implemented geotechnical investigations of Khamza New construction site under the Feasibility Study for construction of Khamza New PS in Bukhara Region. No new investigation were performed for the Khamza New PS. Instead, the information as available from following previously prepared investigation reports are used as the basis for the geotechnical investigation of the proposed Khamza new PS, which is located 300-500 m toward southwest side from Khamza I and Khamza auxiliary PS. a. In 1980 Uzsuvloyiha Design Institute has implemented geotechnical investigations for Detailed Design of Khamza auxiliary PS in Bukhara region. b. In 1984 the Institute has implemented geotechnical investigations for Detailed Design of drainage construction to divert ground waters away from existing Khamza 1 PS area.
GEOTECHNICAL CONDITIONS The proposed site is located at the western slope of Karakul plateau. The plateau consists of deposits formed in Neocene age, covered by Aeolian sands with a thickness from 0.5 to 4-5 m. Deposits of Neocene age are presented by weak sandstones with frequent interlayers and lenses of moderately stronger sandstones and siltstones with a thickness ranging between 0.1 m and 0.5 m. Gypsum content in the soils is to 1.1% of the air-dry soil. According to the operation manual of existing Khamza 1 PS, the elevation of ground water level is 190.5 m (as per 2012). Water is saline, with dissolved salts of sodium chloride & sulfate chloride (8.8-9.4 g/l).
The content of anions of SO4 is 3168 mg/l, HCO3 = 2.8 mg/eqv. Water is aggressive to Portland cement as per standard, GOST 10178-76. Therefore, suggested to use the Sulphate resisting cement as per recommendations of the local standard. Weak sandstone will be the base/sub-soil beneath the foundation of the pump station. Therefore required to confirm it during the detailed geotechnical investigation and design the foundation accordingly to consider the properties and bearing capacity of the existing subsoil. The density/unit weight (dry) of sandstone is 2.67-2.70 tons/m3. The submerged (with natural moisture) density/unit weight of sandstone is 1.59-2.0 tons/m3, while only the skeleton’s unit weight is 1.57-1.83 tons/m3. Unit weight of loose sandstone (with structural damage) is 1.25-1.30 tons/m3, and under compacted condition is 1.39-1.45 tons/m3.
Page 1 of 2
Sandstone filtration coefficient is 3 - 5 m/day. Nominal design pressure is 3 kgf/cm2. The present report does not include any test results for the physical and mechanical properties of the subsoil including the bearing capacity of subsoil beneath the foundation. Therefore, during the detailed design stage further detailed geotechnical investigations of the project site will be required. The final design of structure and its foundation will be based on the properties of subsoil and the recommendations included in the final geotechnical report.
SEISMICITY The proposed project site is located in a seismic zone. The seismicity of the proposed project site of Khamza New PS is assessed at 8 points (in accordance with K K 2.01.03- 96), which can be confirmed during the detailed design of the project. The category of sub- soil beneath footing is Class III with respect to seismic properties of the subsoil and shall be verified during the detailed geotechnical investigation of the site. The FS design of building and foundations of the pumping station is according to the local seismic code “KMK 2.01.03-96” of the country. The design should be verified during the detailed design phase. It is recommended to perform 3-D nonlinear structural analysis and design of the pumping station building as required by the seismic code during the detailed design phase.

InfoCapital Group Topographical Survey
Introduction
The Republic of Uzbekistan (Uzbekistan) is located in Central Asia and its geographical co- ordinates are within 41 00 N and 64 00 E. Its territory extends for 950 km from north to south and for over 1,450 km from east to west, occupying a total area of some 447,400 km2. The Republic of Uzbekistan is divided into 12 administrative units/provinces, ‘wiloyatlar’ in Uzbek or ‘oblast’ in Russian, plus one autonomous republic of Karakalpakstan. The capital city of Uzbekistan is Tashkent, which lies within the coordinates of 41o 20’ N and 69o 10’ E. Uzbekistan is one of the only two doubly-land locked countries of the world, sharing borders with Turkmenistan to the south west, Afghanistan to the south, Tajikistan to the south-east, Kyrgyzstan to the north-east and Kazakhstan to the north and west. It generally lies between the two largest rivers of Central Asia, the Amu Darya and Syr Darya. These two roughly parallel rivers both have their headwaters in the mountains east of Uzbekistan and follow northwestern courses toward the Aral Sea Most of the central and western part of Uzbekistan is rolling dune sandy desert or steppe with the Kyzl Kum desert in the center and the autonomous region of Karakalpakstan, bounded by the Aral Sea and the sparsely populated Ustyurt Plateau, in the north-west. The south and east are dominated by the Tien Shan and Pamir-Alai mountain ranges.
Project Area The proposed project area of Khamza New Pump Station is located in Alat District of Bukhara Province. The significant part of the territory is occupied with desert pasture. The Bukhara Province is located within coordinates of 39o 48’ N and 69o 10’ E. The District of Alat is located on the west of Bukhara province, bordered with Turkmenistan and is about 430 Km southwest of Tashkent. The area is sharply characterized by continental climatic conditions, prolonged hot, dry summers with short periods of precipitation. The proposed Khamza New PS is to replace the existing Khamza 1 PS and Auxiliary Khamza. The existing Khamza 1 PS is located at PK 501+00, on a part of Amu-Bukhara canal (ABMK) and is designed to lift the water up to a height of about 45 meters. The building of existing Khamza 1 was built and constructed in 1965. The water intake into Amu-Bukhara pumping canal is from the right side of Amudarya River in the territory of Turkmenistan. The canal traverses from west to east direction and Khamza 1 along with Khamza Auxiliary is the first pump station on Amu-Bukhara Canal in the cascade of other pumping stations. The canal (ABMK) passes through the Barkhan sands of Kara Kum Desert from Uzbekistan national border to Khamza New PS. After the pump station, the canal passes through Karakul Desert.
The proposed Khamza new PS is located about 300-500 m from Khamza I and Khamza auxiliary PS on the southwest side.
Page 1 of 2 Topographic Survey The Design Institute has accomplished the survey for the Feasibility Study (FS) of Khamza New PS in February 2013. The following coordinate system was used: Projection: Gauss Kruger Datum: Pulkovo 1942, Zone 11 The survey consists of an area survey for the site of proposed building of pump station and a line survey along the center line of the traverse from the intake to the outlet. The area survey is on a total area of about 400 m x 300m and it shows the existing features and the spot elevations of the ground. The spot elevations are shown with reference to a permanent bench mark (Rp – 6 – 13g, elevation 205.762). A total of seven available permanent bench marks are marked and shown on other sheet with their elevations. A line survey along the center line of the traverse of proposed intake channel and discharge channel along with the building is accomplished comprising the cross sections at a longitudinal interval of 100 m and up to 40 m at each transverse side of center line. It is recommended to do a detailed area survey of the site before detailed design is undertaken including the area from the start of intake channel to the end of outlet channel. The detailed survey should show the complete topography of the area including the contours, elevations, existing features, the coordinates and any additional cross sections as required for the detailed design.

Amu Bukhara Irrigation System Rehabilitation Appendix – Financial Management Assessment
I. INTRODUCTION
1. The purpose of this Financial Management Assessment (FMA) is to assess the financial management capacity of the Ministry of Agriculture and Water Resources (MAWR), the Executing Agency (EA) and the financial accounting units to be established under MAWR for the upcoming ADB-financed Amu Bukhara Irrigation System Rehabilitation Project (ABIS Rehabilitation Project). The Project with a cost of approximately $400 million will be implemented over 6 years, starting early in 2013. The estimated project completion date is 30 June 2019 and the loan closing date is 31 December 2019.
2. Within the framework of the FMA the following was undertaken: (i) review and analyse the results of Financial Management Assessment of MAWR, the executing agency; (ii) review of the FMA prepared for the proposed ADB-financed Farm and Agribusiness Development Project in Fruit and Vegetable Sectors (FADP) 2007; (iii) review the EA’s structure and management framework with regard to financial management; (iv) assessment of MAWR’s resources, including its personnel, the scale of Government budgetary support and other sources of income, its information technology equipment and software; and (v) MAWR’s experience in implementing externally financed projects. Consequently, analyses of the EA and PMO’s accounting, reporting, auditing, internal control systems, information systems, and capacity of the personnel were carried out. Additional follow-up interviews with MAWR and PMO staff, discussions with authorities, international financial institutions representatives, and reviews of relevant national legislation were also conducted.
3. The FMA is based on ADB’s Guidelines for the Financial Governance and Management of Projects Financed by the Bank (2002). The instrument used for assessment was ADB’s standard financial management assessment questionnaire (FMAQ).
A. Summary of Findings
4. It is concluded that MAWR currently satisfies ADB’s minimum financial management requirements for EAs. The MAWR has a satisfactory financial management capability to: (i) record required financial transactions and balances; (ii) provide regular and reliable financial statements and monitoring reports; (iii) safeguard financial assets; and (iv) submit the required financial documents to auditors with arrangements acceptable to ADB. A summary of the FMA is given in Table 1.

Table 1: Summary of the FMA
Particulars Rating Conclusions
A. Implementing Moderate MAWR is a government ministry that is accountable to the Agency Cabinet of Ministers (COM) of the Republic of Uzbekistan. MAWR has experience in managing and implementing large scale projects financed by ADB, World Bank, and other international funding institutes.
B. Funds Flow Satisfactory MAWR has knowledge of and working experience in ADB Arrangements funds flow arrangements. Preliminary funds flow and lending arrangements have been identified in consultation with MAWR and Ministry of Finance representatives. Prior to loan negotiations it is essential to ensure the availability of counterpart funds for year 2009, which were not included in state investment program for year 2009.
C. Staffing Moderate MAWR is moderately staffed with experienced financial specialists. Since the project staff will be newly recruited, it is recommended to organize training and workshops on ADB financial management procedures. It is expected that on-the- job training provided by the staff of other PMO/PIU of ongoing projects, being implemented under MAWR, will also be beneficial.
D. Accounting Satisfactory The MAWR accounting policy is based on the Uzbekistan Policies and National Accounting Standards, which are progressively being Procedures modernized in accordance with International Accounting Standards. For ABIS Rehabilitation Project PMO/PIU separate accounting policy, subject to annual updates, and a financial management manual will be established in accordance with requirements of ADB and MOF of Uzbekistan.
E. Internal Audit N.A. There is no internal audit unit within the structure of the MAWR.
F. External Audit N.A. MAWR has not been audited by external auditor but annual procedural audits are conducted by MOF. Operating PMOs under the Ministry are audited by independent external auditors on an annual basis. Audit of the project accounts will be done in accordance with the International Standards on Auditing (ISA), which complies with the requirements of ADB, and this shall be stipulated in the loan agreement.
G. Reporting and Satisfactory MAWR and PMO reports comply with the reporting requirements Monitoring of the MOF, the Ministry of Economy (MOE), and the State Taxation Committee. Acceptable reporting requirements for the proposed PMO and PIUs shall be stipulated in the Loan Agreement between ADB and Government of Uzbekistan.
H. Information Moderate MAWR’s financial system utilizes the 1S Buhgalteriya accounting Systems software supplemented with the use of excel spreadsheets and manual methods. Management and operational units of projects, being implemented under MAWR, use similar accounting software for internal and project operations, as well as financial reporting.

5. Overall, the FMA rated the performance and capacity of the financial, accounting, and procurement management, reporting and monitoring systems of MAWR as satisfactory in serving as an EA for the Project. However it is noted that MAWR should ensure that the PMO is adequately staffed with efficient and experienced personnel, and that MAWR pays special attention to train project staff in procedural and reporting requirements of ADB as a means to enhance staff professional capacity for the following reasons: (i) the accounting policy and procedures of the PMO is required to be established following both national and ADB regulations, which can be easily accommodated as they are not contradictory; (ii) although competent staff are available, it is difficult to retain staff as their period of employment comes to an end as the will leave to take up alternative employment.
6. The following findings and observations have been prepared in accordance with the FMAQ categories and based on interviews, follow-up consultations and supporting documents. The completed FMAQ questionnaire is included in Attachment 1.
B. Country Issues
7. The successful implementation of large scale projects financed by international financial institutions and the Government is conditional on a favourable political and economic environment in the county. At the project preparation stage, it is essential to conduct a general assessment study in order to identify the possible risks arising from environmental factors and inadequate control mechanisms in the country or organizations responsible for implementation and long-term management of development projects funded by the international financial institutions. The following is the summary of these issues that will influence the implementation of the ABIS Rehabilitation Project:
1 (i) The Law on Budgetary System regulates the budgeting process in Uzbekistan. This law provides the legal basis for preparation, review, approval and execution of the state budget. In case of projects financed jointly with International Financial Institutions (IFI), the PMO is responsible for providing the forecasted project budget for the subsequent year to the MOE for approval in May of the current year. (ii) Government is taking strong measures to transform accounting standards in order to make them consistent with IASs. There is sufficient accounting personnel capacity, provided that they are trained and informed about IASs, contemporary financial management techniques and accounting software. (iii) Internal audit in both the private and public sector is very poor in Uzbekistan. Government ministries and agencies do not have a unit responsible for internal control and audit. CRD of MOF is responsible for internal audit of public sector organizations, but both the scope of its work and its human resources are limited.
1 Law of the Republic of Uzbekistan No. 158-II on Budgetary System dated 14 December 2000 and amended on 23 May 2005
Lahmeyer International in association with InfoCapital Group page 3

Amu Bukhara Irrigation System Rehabilitation Appendix – Financial Management Assessment
(iv) In Uzbekistan, the external audit system is being developed based on International Standards on Auditing. External audit is not compulsory for state ministries or agencies. However, Article 1 of the Auditing Law (2000) states that if a certain international agreement signed by the Republic of Uzbekistan lays down rules and regulations other than those contained in the legislation of the Republic of Uzbekistan on audit activity, the former is applicable. Projects financed by IFIs are subject to annual audit by an independent auditor, as long as the loan agreement between the Government and IFIs stipulates this condition. (v) Existing legal and organizational arrangements discussed in CDSR pose considerable risks, and make the public procurement process vulnerable. Institutional and human resources capacity at the level of executing and implementing agencies should be evaluated and possible institutional and procurement arrangements need to be defined at the stage of project appraisal. Procurement of smaller packages should be subject, at least, to International Shopping and National Shopping methods.
C. Executing Agency
8. MAWR will be the Project Executing Agency for the ABIS Rehabilitation Project and have overall responsibility for the Project. A deputy minister under MAWR will be appointed as Project Director and oversee project implementation. MAWR is a ministry of the 2 Government, operated under Regulations approved by the Cabinet of Ministers (COM). In carrying out its activities MAWR is accountable to COM. The Ministry’s organizational arrangements and functions were approved by the same resolution of the COM. MAWR is responsible for overall coordination of the country’s agricultural sector, irrigation and forestry. The Ministry was reorganized in 2003 to fulfil its new roles which now include: (i) formulating agriculture and water policies, (ii) improving and introducing new agricultural and water technologies, and (iii) co-coordinating agencies and service enterprises (either state owned or operating on market based principles). MAWR’s organizational chart and structure of the central administration are included in Attachment 2 and 3, respectively.
9. MAWR is largely a self-financing entity, receiving some funding from the state and contributions from its provincial departments and organizations under its coordination. The current annual budget is around UZS 1.7 billion ($850,000) and it is increased in line with inflation. MAWR has two main functions; support for water resources taking around 35% of its budget and receiving around 35% of its funds from the State, and support for the agricultural sector using 65% of the budget and mostly self-financed from provincial and district contributions. MAWR considers that their current annual allocation is sufficient for their activities.
10. Provincial departments and organizations under MAWR are entitled to receive state budget support. The budget for the O&M of the water sector receives a budget of over $400 million a year. All the procedures regarding their application for budget funds and execution of the budget are coordinated by MAWR.

11. MAWR is authorized to attract foreign investments to finance projects in the fields of agriculture, irrigation and forestry and MAWR has experience in the rehabilitation, upgrade and management of irrigation infrastructure facilities and projects. For example the Land Improvement Project and the Amu Zang Irrigation Rehabilitation Project funded by ADB, and the Drainage, Irrigation and Wetlands Improvement Project of the World Bank are implemented with MAWR as the EA.

For the implementation of ABIS Rehabilitation Project, a project management office (PMO) will be set up in Tashkent and a PIU in Bukhara to facilitate project implementation prior to disbursement of loan proceeds. The PMO will be responsible for: (i) financial management, (ii) procurement and recruitment of consultants, (iii) preparing the periodic reports; (iv) screening, preparation, and implementation of subprojects; (v) ensuring compliance with ADB and Government environment and social safeguards’ requirements; (vi) monitoring and evaluation; and (iv) coordinating interaction with relevant agencies. The PMO and PIUs will have permanent Uzbek staff supported by national and international specialists. Comprehensive results based monitoring and management will be a critical feature of the PMO.
13. Overall guidance and coordination will be provided by a Project Steering Committee (PSC), to be established by government within six months of loan effectiveness to be chaired by a deputy prime minister. The PSC will comprise representatives from the Cabinet of Ministers (COM), MAWR, Ministry of Finance (MOF), Ministry of Economy (MOE), and the State Committee for Nature Protection (SCNP). The PSC will: (i) provide policy guidance, (ii) review and evaluate Project performance, (iii) review audited accounts, (iv) resolve issues affecting Project implementation as needed, and (v) approve jointly with ADB the subprojects recommended by the PMO. The PSC will meet at least semi-annually.
D. Funds Flow Arrangements
14. The proceeds of the ADB loan will be disbursed according to ADB’s Loan Disbursement Handbook (2012, as amended from time to time). For large scale contracts for consulting services and equipment following ICB procedures, loan funds will be disbursed through direct payment. For civil works following NCB procedures and small expenditures related to the PMO, reimbursement and imprest fund procedures will be applied. For minor goods or services procured at provincial levels payments to suppliers can be done through corresponding PIU.
15. In accordance with ADB’s project implementation guidelines, after loan effectiveness, MAWR will open two imprest accounts, one for each loan (ADF and OCR) at a commercial bank in Uzbekistan acceptable to ADB. These imprest accounts will be established and managed according to ADB’s Loan Disbursement Handbook. Total outstanding advances are not to exceed estimated share of eligible project expenditures to be financed through the imprest account for the next 6 months or 10% of the loan amount, whichever is lower. ADB’s statement of expenditures procedure will be applied when reimbursing eligible project outlays and liquidating and replenishing the imprest accounts for individual payments not exceeding $100,000. As per banking regulations in Uzbekistan, the PMO will be required to establish two bank accounts, one for foreign exchange and second account for local currency. The foreign currency account will be used by PMO as its imprest account.

16. During the implementation of previous projects, PMOs operating under MAWR faced delays in receiving counterpart funding for settlement of payment requests to contractors and suppliers tendered at the local level. This is related to inappropriate practices of PMOs in sending requests for funds to MOF. It is important to ensure PMO staff are aware of the correct procedures.
17. As is discussed in the CDSR, in line with the state budgeting process the PMO should identify the project expenditure budgeted for in the upcoming year and send it to the MOE (through MAWR) in May of the current year. Later the request for funds will be sent to MOF. With respect to Amu Bukhara Rehabilitation Project, expenditure needs for the upcoming 2013 year were not considered in the state budget for year 2012, since the feasibility study is not yet approved by the COM. Therefore before the loan agreement is finalized, it will be essential to ensure that the budget for project start-up is available for the initial fiscal year.
18. The overall budget for project implementation is included in the Presidential Decree for the Project as an annex, to ensure that sufficient funds are budgeted for each component for each year of implementation.
19. Lending and re-lending arrangements. Since the ABIS Rehabilitation Project is a non-revenue earning project (for MAWR), Government will take the responsibility for repaying the ADB loans. The project beneficiaries are not expected to provide reim- bursement of loans and or to pay for services provided by the project.
20. Management of foreign exchange. MAWR is not greatly experienced in managing foreign exchange risks. MOF needs to be consulted regarding this issue prior to the finalization of loan agreement.
E. Staffing
21. It is proposed that the PMO will be headed by a Project Manager appointed by MAWR and acceptable to ADB. The Project Manager will report to the Project Director. The Project Manager will be supported with national specialists for procurement, financial management, accounting, engineering, social and environmental safeguards, water management, and M&E along with administrative staff. PMO staff will be recruited by the EA using procedures acceptable to ADB. The PMO will be supported by international and national consultants recruited through the Project.
22. To ensure adequate financial and accounting capacity it is proposed to recruit a financial manager and an accountant for the PMO and accountants for the two PIUs who will serve for the duration of the project in the respective locations. In selecting the project financial personnel, special attention will be paid to the experience of the staff with IFIs. Project accounting and finance staff will be trained in ADB procedures. PMO personnel are usually employed on one-year contracts, which are renewed for the subsequent year subject to satisfactory performance of the staff member.
Lahmeyer International in association with InfoCapital Group page 6

Amu Bukhara Irrigation System Rehabilitation Appendix – Financial Management Assessment
23. Competent staff are available but it is difficult to retain staff as their period of employment comes to an end as the will leave to take up alternative employment. The cap on the salary rates that can be offered that is imposed by government does restrict the PMO in flexible recruitment and remuneration.
F. Accounting Policies and Procedures
24. MAWR through the PMO will be required to establish financial management and accounting systems for the Project in accordance with Financial Reporting and Auditing of Projects Financed by the ADB. The PMO will also be responsible to maintain project accounts and financial statements.
25. MAWR and its PMO use the accrual method of accounting in their regular and project operations. The accounting system of MAWR, as well as of all state and private legal entities in Uzbekistan, is based on the NAS and the national accounting guidelines of the MOF. As it is practiced in other ADB financed projects, the PMO will develop a project accounting manual in accordance with ADB and MOF requirements. The manual will be updated annually to include project accounting policy changes issued by the MOF. The PMO and PIU follow the procedures stipulated in ADB’s Handbook for Borrowers on the Financial Governance and Management of Investment Projects Financed by the ADB (2003). The Chart of Accounts based on NAS 21, in Attachment 5, will be applied by the PMO.
26. All reports and supporting documents on all transactions will be stored and retained by the project financial manager until documents are inspected by state controlling agencies (District Tax Inspection, MOF), after which documents will be stored in archives.
27. Clear segregation of duties will be implemented at PMO level. The Project Manager is authorized to execute the project transactions while the financial manager and the accountant handles recording of the transactions. Payments are approved and made by the project manager and the financial manager. In order to increase transparency and reduce potential misappropriation the double checking system (i.e. requiring the documents to be signed by two persons) for bank reconciliations has been found to be the best alternative in MAWR, since the number of PMO accounting personnel is limited in the case of non-revenue earning projects.
28. Budgeting System. The Ministry’s and the PMO’s budgeting systems will be separate and follow a clear process. The project’s budgets are to be prepared annually by the PMO manager together with the financial manager and other management staff as appropriate. The budget developed by the PMO sets annual physical and financial targets. The budget is presented to the MOE, which after approval, is submitted to MOF for final approval.
29. During project implementation the actual expenditures are compared with planned budgeted expenditures on a monthly and quarterly basis, and reports on an analysis of variations is prepared. Significant variations in budgeted expenditure need to be approved by the PSC prior to actual expenditure.
Lahmeyer International in association with InfoCapital Group page 7

Amu Bukhara Irrigation System Rehabilitation Appendix – Financial Management Assessment
30. Procurement. All ADB-financed procurement of goods, works, and consulting services will follow ADB’s Procurement Guidelines (2007, as amended from time to time). Civil works contracts costing more than $1 million and contracts for supply (and installation) of equipment and materials valued at more than $1 million, will be awarded under international competitive bidding (ICB) while those valued at $1 million or less will be awarded following national competitive bidding (NCB) procedures acceptable to ADB. Equipment and materials packages valued at less than $100,000 will be procured through the shopping mode. The relevant sections of ADB’s Policy on Anticorruption (1998, as amended to date) will be included in all bid documents issued during implementation of the Project.
31. Currently, there are ADB, World Bank and other donor-financed projects under the management and supervision of MAWR. The MAWR has improved its capacity in procurement by participating in these projects and by involving its staff. The Government has established a Tender Commission with an Evaluation Committee. The Evaluation Committee’s membership has several MAWR staff (of the five to seven members, two to three are from MAWR) who take part in decision making for the procurement evaluations. In the Tender Commission, MAWR also has staff participating. By participating in these tenders, MAWR staff have improved their skills in following guidelines for procurement and knowledge of bidding process for international donors. MAWR has established a library of reference materials related to procurement from the various donors.
32. Payments. All project payments are made with payrolls and bank transfers. In accordance with national accounting procedures, instead of invoices, the payroll is stamped (PAID) and assigned an accounting code. Payrolls prepared by the PMO’s accountant are to be checked by the financial manager and the project manager.
33. Cash and Bank. The PMO manager and the financial manager will be the duly authorized signatories to all project-bank transactions. Use of the accounting software “1S Buhgalteriya” (to be installed in the PMO) will allow maintaining the cashbook in a computerized electronic system. Bank reconciliations are to be undertaken at the end of each month, or at any time as necessary.
34. Safeguard over Assets. MAWR and its PMOs have procedures that assure sufficient controls are undertaken over project assets, and safeguards are in place to protect assets from fraud, waste and abuse. An annual physical inventory of all stocks and materials is carried out as required by NAS and the fixed assets inventory is required to be updated every two years. An inventory stock-take is also practiced when the chief accountant or office manager is changed.
G. Internal Audit
35. As it has been described in previous FMAs for MAWR, currently there are no internal audit units in any government ministry or entity in Uzbekistan. MAWR does not have a department for conducting internal audit of either the ministry’s or project operations. Although the PMOs of ongoing projects executed under MAWR prepare monthly, quarterly and annual financial statements to the financial and economic department of the ministry, these are not intended for internal audit purposes.
Lahmeyer International in association with InfoCapital Group page 8
InfoCapital Group
Amu Bukhara Irrigation System Rehabilitation Appendix – Financial Management Assessment
36. In Uzbekistan, the Control Revision Department (CRD) of the MOF is the equivalent of a Supreme Audit Institution. This department carries out an internal audit of MAWR, usually every year. However, CRD is mainly concerned with inspecting the compliance of the ministry with budget rules and regulations. CRD does not conduct a “value-for-money” analysis and the department is not involved in identifying gaps in internal control systems and making recommendation on strengthening them, features that are accepted as part and parcel of modern internal audit processes.
H. External Audit
37. Since the state agencies are not required to undergo external auditing, MAWR has not been audited. However, as part of ADB’s conditions PMOs under MAWR are subject to annual external audit. In other ADB financed projects external auditors are selected based on competitive bidding process in accordance with ADB requirements. For the ABIS Rehabilitation Project independent auditors acceptable to ADB will audit the accounts and records yearly to international standards on auditing and in accordance with the provisions of the Loan Agreement and as specified in ADB guidelines. Annual expenditure for an external auditor during project implementation are included in project costs with provision for loan proceeds to finance the services of private auditors and the translation of their reports into English. Terms of reference for external auditor, in accordance with ADB regulations, shall be prepared for the Project after establishment of the PMO.
38. The PMO will have to maintain separate accounts for the Project. Within 6 months of the close of the financial year, certified copies of the audit report, together with the auditor’s opinion, will be submitted by the PMO to the Government and ADB in English. The audit reports will include a management letter and a separate opinion on the use of the imprest accounts and statement of expenditures procedure. The Project is subject to central Government audit by MOF only at project completion, unless any major accountability issue is raised that would warrant carrying it out sooner.
39. The external audit undertaken of MAWR PMOs is carried out in a timely manner and issues and recommendations made by the auditions are implemented promptly where appropriate.
I. Reporting and Monitoring
40. MAWR financial reporting follows the NAS procedures and requirements. The Financial and Economic Department of the Ministry prepares reports on budget execution and internal financial activities. These reports are prepared using the computerized accounting software and spreadsheets following existing templates where necessary. The types of reports prepared and their frequency is presented in Table 2 below.

41. Project financial statements are prepared using a computerized accounting system and submitted to MAWR, MOE, MOF and ADB on a monthly, quarterly and annual basis. The quarterly project progress reports highlights the physical accom- plishments and financial progress and follow ADB formats. Spreadsheet analysis and reports are prepared to adapt to special and supplementary reporting requirements. Based on previous project implementation experience, MAWR has well established financial management reporting responsibilities that specify the type and requirements for reports to be prepared. MAWR through the PMO will establish financial management and accounting systems for the Project in accordance with Financial Reporting and Auditing of Projects Financed by the ADB. PMO will also be responsible to maintain project accounts and financial statements.
42. MAWR, through the PMO, will submit quarterly and annual reports to ADB. The reports will indicate progress made, problems encountered, steps taken to remedy the problems, and a program of activities along with expected progress during the remainder of the implementation period. The reports will also incorporate project performance monitoring data and all relevant financial data. The reporting system will focus on outcomes, efficiency, and quality and will be consistent with international and local reporting standards, as well as with the design and monitoring framework. MAWR will also provide other reports and information relating to the Project as ADB may reasonably request. Within 6 months of project completion, MAWR will submit a project completion report to ADB that includes information on project implementation, use of both the ADF and OCR loan proceeds, and accomplishments in relation to the Project’s outcome and impact.
43. In general ADB requires the reports listed in the following Table 3 to be prepared by the PMO:

J. Information System
44. MAWR uses 1S Buhgalteriya accounting software package that is integrated with the Internet for exchange of information. For complimentary reasons, the PMO should use a similar computerized financial accounting and management system. The system should enable the PMO to: (i) respond to operational and project-related queries pertaining to specific accounts, and (ii) prepare financial reports on the transactions that occurred in the reporting period. The accounting system should be capable of generating financial reports for both external and internal use. For some types of reports PMOs use spreadsheets.
45. The PMO will establish a Project Performance and Monitoring System to monitor the Project’s progress in achieving the planned outputs, outcome, and impact within 6 months of loan effectiveness. An M&E unit will be established in the PMO to measure results and report findings to the Government and ADB. During project inception, a matrix of indicators will be confirmed and baseline data for the agreed indicators will be gathered. The indicator data will be updated every 6 months and reported to stakeholders and the public. During loan review missions, the indicators will be validated and may be modified to reflect Project performance and results more accurately.
K. Conclusions
46. Overall, the FMA rated the performance and capacity of the financial management, reporting and monitoring systems of MAWR as satisfactory in serving as an EA for the Project. However it is noted that MAWR should ensure that the PMO is adequately staffed with efficient and experienced personnel, and that MAWR pays special attention to train project staff in procedural and reporting requirements of ADB as a means to enhance staff professional capacity.
Lahmeyer International in association with InfoCapital Group page 11

Amu Bukhara Irrigation System Rehabilitation Appendix – Financial Management Assessment
47. Accounting and financial reporting practices of the PMO under MAWR are found to be reliable. The accounting policy and procedures of the PMO is required to be established following both national and ADB regulations, which can be easily accommodated as they are not contradictory. As the ABIS Rehabilitation Project executed by MAWR is a non-revenue earning project, the number of accounting and financial personnel assigned to PMOs is limited as they are only accounting for expenditure, not receipts. However, the reliability of the accounting documentation will be ensured by the current system of authentication that requires double signatures (i.e. signing by two persons) for the most of the accounting documents. As it is practiced by other PMOs, ABIS Rehabilitation Project financial reporting will be computerized, and it will not necessitate any changes in MAWR’s financial reporting system.
48. It is noted that there is no department within the structure of MAWR responsible for internal audit and that the Ministry has not been audited by external independent auditor, apart from the procedural audits that are required to conduct by MOF. This means that is very important that for projects being implemented under MAWR an external annual audit is carried out in a through and timely way in line with the external donor requirements, as will be the case for the ABIS Rehabilitation Project.
