(Apart from selected 16 dams for rehabilitation)

9.0 Planning & Designs Sub Department

9.1 Water Resources & Project Planning Branch

The following items of works had been carried out by the water resources & project planning (WR & PP) branch during the year 2009.

9.1.1. Pre-feasibility Study of Ellewewa Reservoir Project

Panamure anicut scheme is located across Kadigan Ara which is a tributary of Hulanda Oya in Walawe basin in the city of Embilipitiya. This scheme is depended on in-basin water resources from Kadigan Ara & the diverted water received from Kithalabokka anicut which is located across Eraporu Ganga, through a transbasin canal. Irrigable areas of Panamure scheme is scattered over the Kadigan Ara sub basin & irrigation water is provided from a cascade of 07 anicuts across Kadigan Ara.

During the drought periods, at the tail end of Yala season, Kadigan Ara flow goes dry & irrigation water supply get affected especially during the months of February & March. Reason for this water deficit is mainly due to increase in irrigable area owing to the encroachment by new settlers. At the beginning of Panamure scheme, about 215 Acs. of paddy lands were fed & presently it have been increased up to 1250 Acs. In addition to provide the irrigation water deficit, drinking water supply from a reliable water source is demanded by the people in Panamure area through irrigation engineer Ratnapura & local political authority.

Under the pre-feasibility study it is proposed to construct Ellewewa reservoir (2.4 MCM) across Kadigan Ara and to store water during rainy reason. During drought spell of the year water will be released to Kadigan Ara through the sluice and existing irrigation infrastructure will be used to provide irrigation water to the irrigable area. During the study it was revealed that the generation of hydropower also possible and a 0.7 MW hydropower plant will be established in right bank with 2.0 Gwh annual energy as an extra benefit by this project. A morning-glory spillway will be constructed at left bank in addition to a natural spillway (breach section at HFL) provided at right bank in case of higher flood larger than the design flood. Under this pre-feasibility study, hydrological analysis, flood study, operation study, design of morning-glory spillway, design of hydropower plant & related structures, economic analysis, preparation of cost estimate & relevant drawings were completed.

9.1.2. Kaluganga Multi-purpose Development Project

A special cabinet committee chaired by Hon. Prime minister requested the Irrigation Department to study on Kaluganga basin and submit a project proposal/concept paper to harness the Kaluganga water resources while reducing the flood menace, which has become a nuisance to the people living in the low lying areas of the basin. Under this concept paper preparation, previous study reports prepared by local & foreign consultants were studied and their recommendations were considered in order to propose the best option available for Kaluganga basin. In order to minimize flooding situation in down stream, it is compulsory to construct

35 reservoirs in up stream to arrest flood volume. Therefore as recommended in previous studies too, it is required to construct Malwala and upper Kukule reservoirs. However with these two reservoirs alone it will not be possible to minimize flooding in down stream. Hence flood bunds and gravity outlets too required in downstream for flood protection.

During this project proposal study, operation studies were carried out with updated hydrological data and other related parameters. From the operation study, to minimize flooding in Ratnapura, it is required to construct a reservoir with 250 MCM capacity for safeguarding a 20 yr return period flood. Evaluation of hydropower potential was based on the runoff records available for a period of 42 yrs and the optimum installed capacity was 13 MW with 61 Gwh of annual energy.

Upper Kukule reservoir was proposed across Kuda Oya, upstream of existing Kukule run-of the river diversion weir. Existing power house will not be affected due to proposed reservoir & power house as the down stream flow will be guaranteed. Evaluation of hydropower potential was based on the run-off records available for a period of 12 years at Kukule gauging station. Optimum installed capacity was 6 MW and 25 GWh of energy could be generated annually.

Preliminary designs of concrete faced rock fill dams, spillways, economic analysis and report was prepared during the year 2009.

9.1.3. Batuwita Ara Reservoir Project

This proposal had drawn the attention under the Nilwala Ganga Action Plan in 1990s. Initially this project was proposed under ‘Rectification of Nilwala Ganga Scheme’. Terms considered under the new action plan were broader thus incorporating flood control and supply of potable water in addition to the supply of water for irrigation. Initially the task was attributed with Nilwala Basin Project office and they had come up with three alternative solutions basically to address flood control for probabilistic floods of 2 years, 10 years and only for irrigation requirement to cater an irrigable area of 310 acres of paddy lands in both seasons. Later the task was under taken by this branch and hydrological analysis was carried out based on actual rainfall data and stream flow data for last twenty years. This study included a more detailed flood control analysis for last 20 years based on different reservoir scenarios.

In order to obtain the reservoir parameters and to analyze the behavior of the proposed reservoir against the objectives, the operation study was carried out based on the inflow time series. From the results of the operation study an optimum of 1030 ac.ft. of active storage capacity was selected. The maximum height of the earth bund was 57 feet at the river section.

Based on the geological conditions, location, economy and the scale of the project it was decided to provide a morning-glory spillway for this reservoir. In order to minimize the cost, the sluice is incorporated with the spillway structure.

9.1.4. Proposed Aparekka Ara Reservoir Project

Proposed Aparakka Ara reservoir is located in across Aparekka Ara Nilwala basin. This reservoir is aimed to irrigate about 600 Acres of paddy lands in both Yala / Maha seasons. It is further expected to mitigate down stream flood potential and to be used as a source for potable water supply.

An inflow series was generated for Aparekka Ara proposed location in order to carry out the operation study for a period of 20 years based on actual rainfall data obtained from the Meteorological Department (from 1989 to 2008). Based on that data a number of possible alternative reservoir scenarios were analyzed to obtain the optimum reservoir parameters. Flood analysis was carried out for 100 yr probable flood. Finalized a suitable bund section and fixing reservoir parameters are in progress.

36 9.1.5. Downstream Development under Uma Oya Project

Uma Oya is one of the major tributaries of Mahaweli Ganga which is the largest river in Sri Lanka. Uma Oya flows northeastward across the central highlands at about elevation of 1000 m msl & discharges in to Rantambe reservoir at Bembiya. Uma Oya multipurpose project envisaged to divert water from Uma Oya to Kirindi Oya after harnessing hydropower potential and to irrigate dry & less developed southeastern region of Sri Lanka. After generating hydropower, water conveys to Alikota Ara which is a tributary of Kirindi Oya. About 150 MCM of water will be diverted annually from Uma Oya to Kirindi Oya under the proposed development.

The proposed capacity of Alikota Ara reservoir is around 2 MCM. Since the low capacity of proposed Alikota Ara reservoir, it is required to transfer water to proposed Kuda Oya reservoir through Alikota Ara right bank main canal while releasing water to Kirindi Oya. The part of water picked up at Handapanagala anicut will be diverted to Handapanagala reservoir while the balance will be utilized for irrigated agriculture in minor tanks through proposed Handapanagala Anicut right bank canal. If excess water is available after storing in above major and minor tanks, it can be allowed to flow to Kirindi Oya reservoir to meet the enhanced drinking and industrial demands of the region.

Water released from the sluice of Alikota Ara reservoir to Kirindi Oya, will be picked up at existing Handapanagala Anicut. Handapanagala anicut consists of existing left bank & proposed right bank feeder canals. Handapanagala existing left bank feeder canal conveys water to Handapanagala reservoir. Proposed Handapanagala right bank feeder canal conveys water to ancient abandoned Yoda Ela & will feed existing & proposed new tanks & irrigable areas in Ethili wewa area. It is expected to increase the capacity of existing Handapanagala right bank main canal and to construct a new left bank main canal in order to irrigate more lands under Handapanagala reservoir. Also, it is expected to raise the bund in-order to increase the capacity of Handapanagala reservoir.

Proposed Kuda Oya reservoir is to be constructed across Kuda Oya which is also a tributary of Kirindi Oya in order to feed identified irrigable areas in Kuda Oya right bank side & identified irrigable areas in adjacent basins. Kuda Oya reservoir right bank canal is planned at a higher contour closer to the ridge of the Kuda Oya in order to feed identified irrigable areas in right bank side of Kuda Oya and Kahakurullanpellessa and Sinhalayagama tanks which are located in dry areas in the adjacent Mau Ara and Malala Oya basins respectively. In addition to Kuda Oya right bank area, it is expected to release water to Kuda Oya from the sluice of the proposed Kuda Oya reservoir in order to irrigate from Ussella anicut. Right bank canal of the Ussella anicut is much lower in elevation to Kuda Oya right bank main canal and planned to feed several minor tanks & irrigable areas in right bank of Kuda Oya and in Thanamalwila area.

Diverted Uma Oya water is planned to be utilized for irrigation demands of new irrigation areas in both Yala & Maha and irrigation demands of existing areas during Yala. Altogether, it is expected to develop about 5000 ha of lands in southern part of Sri Lanka.

9.1.6. Kumbukkan Oya Basin Development Project – (Nakkala Reservoir & Mandappan Oya Reservoir)

Presently within the Kumbukkan Oya basin there are no major storage tanks across the main Kumbukkan Oya and there are few anicut schemes. Kumbukkana anicut has about 2100 Acs. of paddy lands and the present cropping intensity is about 1.5. Proposed project envisaged to increase the cropping intensity of the scheme up to 2 and planned to irrigate new lands of 2,000 acs in Kumbukkan Oya basin. (500 Acs. under Yakurawa anicut, 750 Acs. under Therappahuwa anicut and 750 Acs. under Nugamandiya anicut). In addition to irrigated agriculture it is proposed to provide drinking water to Moneragala district.

Proposed project envisaged to construct two reservoirs. One is across Kumbukkan Oya at Horagolla, upstream of the Nakkala & the other is across the Mandappan Oya which is a tributary of Gal Oya at Karametiya.

Kumbukkan Oya is the major river in the Moneragala district. Average annual inflow to the proposed reservoir at Nakkala is about 201 MCM. There is no possibility of utilizing this water within the Kumbukkan Oya basin alone due to topography of the area.

37 Therefore part of this water has to be diverted to the adjacent Gal Oya basin through a tunnel to develop the lands in Moneragala district. It is proposed to irrigate about 5000 Acs. under the proposed Mandappan Oya reservoir.

Collecting of rainfall data, hydrological studies for proposed reservoirs were done during the year 2009 & reservoir sizing is in progress.

9.1.7. NCP canal Project

Under the original Mahaweli master plan of 1968, five major reservoirs were proposed. Out of five Kothmale, Victoria, Randenigala and Rantambe reservoirs have been completed. The fifth major reservoir Moragahakanda is now under construction and it is across Amban Ganga, a major tributary of Mahaweli Ganga.

The original master plan envisaged to convey Moragahakanda water to the North-central province through a ridge canal (NCP canal) and continues beyond Vavuniya district and enters into Kanagarayan Aru in Kilinochchi district to feed Iranamadu tank.

To justify the viability of the project it is necessary to assess the water availability in the Mahaweli system in order to transfer excess water to NCP canal. For this task water availability at Minipe Anicut and Polgolla-Amban Ganga complex was assessed based on the water issues data issued by MASL during the year 2009.

9.1.8. Kadukanna Reservoir Project This proposal was forwarded to action plan of Nilwala rehabilitation programme by the farmers of the area. The proposed Kadukanna reservoir is located in Nilwala river basin in Matara district. There is no reliable water source for the surrounding paddy lands. Although there are few anicuts across Kadukanna ara to irrigate the paddy lands, water in the stream is not sufficient to meet the demand during the dry spells of the year. On the other hand, these lands are inundated damaging crops during rainy seasons and this water drains to downstream lands resulting minor floods. Hence, some sort of regulation of the flow of the Kadukanna ara is quite necessary and hydrological studies, operation studies & preliminary designs of structures were completed during 2009. 9. 2 Designs Branch

9.2.1 Designs Branch - 1

The Design works carried out in the Design Branch 01 are as follows:

9.2.1.1. Deduru Oya Radial Gated Spillway The proposed Deduru Oya Reservoir will impound 75 MCM water at the Full Supply Level of 70.99 m MSL. The proposed spill way consists of 8 No 8.50 m(W) X 8.00 m(H) Radial Gates.

Originally the Energy Dissipation was proposed by providing a stilling Basin. But considering the amount of hard rock to be excavated and removed, later it was decided to do away with the stilling basin.

Accordingly the entire Design was redone and completed during the year 2009.

9.2.1.2. Rambukkkan Oya Blocking Out Plan

Rambukkan Oya Reservoir Project was proposed to irrigate 3500 Ac. of land. The Blocking Out was done on a 2.5 Ac lot basis. Due to the scarcity of irrigable land the Blocking Out Was redone keeping the individual lot size as 1.5 Ac.

The canal net work consists of 6.7 km long Main Canal, 8 No Distributory Canals and 56 No field Canals. The canal net work was laid so as to feed the existing tanks in the vicinity and creating possible new tanks en route the canal network. Accordingly one medium tank, six village tanks and three new village tanks will be fed by the Rambukkan Oya reservoir.

The Irrigable area consists a total of 2305 lots under 5 Tracts. The total area blocked out is 3457.5 Ac.

38 9.2.1.3. Proposed Branch Canal No2 in Kaudulla Reservoir Scheme.

The development of Branch Canal No2 was proposed to resettle farm families who are displaced by Moragahakanda Reservoir impounding.

In the development of irrigable area the concept of ”DUAL CANAL SYSTEM” is introduced. Under this system, separate canals are formed for paddy and Other Food Crops. Normal field canals feed the paddy area 24 hours a day as practiced at present. The canals feeding other Food Crops are named Upper Canals and operate during the day time only. At night these upper canals are closed. Upper canals are fed by newly formed “High” tanks or existing minor tanks. These tanks store water during night and feed the canal during day time. The Tracts 1,2,3 and 4 under Branch Canal No. 2 are initially selected for Blocking Out. Each block is 1.5 Ac in extent .The Land use survey Maps were used to identify suitable Lands for Paddy and Other Food Crops. While existing village tanks are proposed to be fed by the cannel net work new Low and High Tanks are proposed wherever possible.

Accordingly 1051 paddy lots and 685 Other Food Crop lots are blocked out totaling an extent of 2604 Ac.

10.2 Drainage Branch

10.2.1 Introduction

The Drainage Branch is an established under the sub department of Environment, Drainage and Flood Protection. The main objective of the Drainage and Flood Protection branch is to minimize the damages to the public and private properties (including crops) due to flood damages problems and salt water intrusion.

The main function of the drainage branch is maintenance of the drainage & flood protection and salt water execution schemes under the preview of the Irrigation Department.

At present the drainage branch is assisting the planning branch in formatting proposals on new flood protection, drainage and SWE projects. Since the coastal drainage & flood protection and SWE subjects are complex in nature, the experience gathered during the operation of existing schemes is essential in designing new projects. Therefore the drainage branch has to be fully developed to undertake planning of drainage, flood protection and SWE projects in future.

Most of the drainage & flood protection SWE scheme implemented in the past have been deteriorated due to

1. Increases in O & M cost and decreases amount of annual allocation. 2. Lack of interest in paddy farming due to less profit. 3. Invasive aquatic plants in the drainage canals. 4. Sea level rise and climate change and sand mining in rivers and coral mining in coastal regions. 5. Reduction of wet lands due to garbage filling and housing scheme and encroachments. 6. Water pollution due to urbanization.

45 Most of the pumps installed in old drainage & flood protection scheme have been removed due to energy crises. (high fuel and electricity priced)

New engin installed at Magalagoda pump house Nilwalaganga drainage and flood protection scheme

10.2.2 Work done under the Drainage & Flood Protection in 2009

(a) O & M of Drainage and Flood Protection works:- Rs. 34.0 Million was provided in 2009 under block votes for Major Drainage & Flood Protection Schemes in Ampara, Batticaloa, Colombo, Galle and Southern range.

(b) Funds were allocated to above schemes to protect of paddy cultivation land by maintenance over 186 km length of flood bunds.

(c) Provided Drainage facilities to cultivation lands by maintaining over 825 km length of drainage canals under the Drainage and Flood Protection.

(d) Funds were also allocated to operate & maintain over 70 no. of pumps of the drainage and flood protection schemes in Nilwala ganga, Gin ganga and Kelani ganga flood protection schemes to facilitate protection of more than 13,000 Ha of paddy lands.

(e) Replaced 04 Nos. of trash tracks at Ginganga Scheme

.(f) Repaired one of lighting protection tower and panel board at Ginganga Scheme.

(g) Priority is given to Nilwala Ganga flood protection scheme where owing to aging of existing diesel pumps in 3 pump houses; paddy cultivation were faced numerous flood threats. Therefore Repaired 04 Nos. of Diesel pumps at Tudawa pump house and replaced 2 diesel engines with new ones. Replaced one diesel engine at Magalagoda pump house; in 2009.

(h) Irrigation department was able to arrange to Purchase 02 Nos. of new diesel engines for Nilwala ganga scheme in 2009 for the worth of 21.4 Million rupees and arrangements have been made to purchase another five diesel engines for the value of 60 Million rupees in 2010. New Excavator was purchased in 2009 for the value of 7 Million rupees and handed over to Irrigation Engineer (Gin Ganga) to facilitate dredging of drainage canals.

The Gin Ganga and Nilwala Ganga flood protection schemes are the largest flood protection scheme in Sri Lanka. The total protected extent of land under scheme is around 25000 Acs. (each scheme protects 12500 Acs.) Although those 2 are called flood protection schemes, those schemes include flood protection drainage and salt water execution also.

There are similarities in these schemes. Component table is given below.

CONSTRAINTS ENCOUNTERED

The main constraints in this Region are shortage of staff and lack of good motorable vehicles for plying on rough track roads in outskirts. The available staff is inadequate for the heavy workload including project works that is being carried out in this Region in Vavuniya and Mannar Districts. The works are being done with dedication and commitment even on weekends to fulfill the expected Programs and targets, with a shortage of staff and frequently break down vehicles.
