Respected Sir,

With reference to the above cited subject and references mentioned above, we are submitting IIT approved DPR with tentative revised contract value details for your necessary review at the earliest. Please note that any variation in demand, population, quantity variation, design parameters, EMI specification from vendors or other parameter can affect the RCV. As of now land handing over process of the structures is not completed even after completion of 6 months of the valuable project time, changes in location of the structure will also affect the RCV.

Thanking you and assuring of our best services at all times.

Yours faithfully, For Larsen & Toubro Limited

(D) SIMPLE GRAPHICAL METHOD: -

In this method, the population curve of the city (i.e., the population vs. past decades) is smoothly extended for obtaining values for the future. The line of best fit has been obtained by the method of least squares. Based on this comparison, a graph of populations versus decades is plotted and extrapolated;

(E) SEMI-LOG GRAPHICAL METHOD: It is useful for data with exponential relationships, or where one variable covers a large range of values. This is a line with slope and vertical intercept. This method gives increased values compared to the figures obtained by the arithmetical increase method with increase in duration. Following table shows the projected population for future years by this method;

SUMMARY OF PROJECTED POPULATION: - The population has been projected by various methods and has been summarized in the Table below: -

Projected ARITHMETICAL Geometric Incremental Semi Log Simple Year INCREASE Mean Increase Graph Graph METHOD: Method method Method Method 2023 176664 230206 188827 296975 181335 2038 220898 423816 266924 598620 228250 2053 265133 780258 365753 1206655 275170

The computation of projected population worked out by the Geometrical increase and Semi- log Graph method are on higher side. The results obtained by the Arithmetical Increase method and Simple Graph method are lower side, results obtained by the Incremental Increase method are closer to, and in accordance with the pattern of growth of population in the villages. Out of the above population growth arrived at by Incremental Increase method appear to be more reasonable/realistic and conform to the pattern of Growth of Population.

Among above villages, certain portion of Kuldomari & Auri is already considered under Jal Jeevan Mission. For reduced villages population projected as follows:

Sensitivity: LNT Construction General Business “Construction of Parasi and Belawadh Group of Villages Water Supply Scheme, District- Sonbhadra (Based on Surface Water) and relevant works including Commissioning and Operation & Maintenance for 10 Years” NIT No. 113/W-17/BID/2020

3. Design Basis:

The water supply projects are designed to meet the requirements over a 30-year period.

• Base year - 2023 • Intermediate design year - 2038 • Ultimate design year - 2053

In this project, various facilities of water supply works are designed to meet the requirement of the following design periods.

Table 5: Design period of various facilities in water supply system Design Period Sr. No. Facilities in Water Supply Works (Years) 1 Intake Arrangement 30 2 Pumping a. Pump House 30 b. Electrical Motors and Pumps 15 3 Water Treatment Unit 30 4 Pipes for Raw Water and Clear Water Mains 30 5 Overhead Tanks 30 6 CWR at WTP and other 6 locations 30 7 Distribution System 30

3.1. Operating Hours

The operating hours of various systems such as Raw Water Pumping system, Water Treatment Plant, Clear Water Pumping system and Distribution system have been designed based on the guidelines provided in the agreement by client. The same has been considered in all our designs and it is shown in the Table 6 below.

Table 6: Designed operation hours of various systems

Operating System Hours / day

Raw water transmission 16 Water Treatment Plant 16 Clear water transmission 16 Distribution system 24

LARSEN & TOUBROIMITED 18

3.2. Residual Head and Peak Factor

The distribution system will be designed for a minimum residual pressure of 10 m wherever the road network is more than 25 km; 7 m minimum pressure will be assured wherever it is less than 25 km and difficult to maintain 10 m. As the water supply project is designed for rural areas. Peak factor of 3 is considered for the design as the distribution system is designed for only 24 hours of supply a day.

For all transmission designs residual pressure of 3 m is maintained at the end nodes.

3.3. Design Criteria for Head Loss or Pressure Drop

Friction Head Loss per Meter of pipe are computed by using Hazen William Formula given below:

Q= [1.292 * 10^-5 * C * (d^2.63) * (S^0.54)]

Where, C - Hazen William coefficient d - Pipe Diameter in mm Q - Discharge in cubic meter per hour S - Friction Slope The maximum Headloss Gradient considered in pipe line is 4 m/km Note: Station Loss of 2 m is considered at every pumping station.

3.4. Hazen William Co-efficient

A factor or value used to indicate the smoothness of the interior of a pipe. The higher the C Factor, the smoother the pipe, the greater the carrying capacity, and the smaller the friction or energy losses from water flowing in the pipe. It is used in calculating the relative roughness of a pipe against the size of its diameter.

In this case, following C values for DI and GI pipes are taken:

▪ DI pipes, C = 140 ▪ GI pipes, C = 100 for 80 mm &65mm diameter and 55 for 50 mm diameter.

3.5. Pipe Material

The pipe material used for raw water rising main, clear water pumping mains till OHTs is Ductile Iron of class K9. MS Pipes of required thickness are proposed at all River/ stream/ canal crossings, Railway crossings & NH crossings. Ductile Iron pipes and Galvanized Iron Pipes have been considered for distribution. DI pipes have been considered as per IS 8329:2000. Internal

LARSEN & TOUBROIMITED 19

cement mortar lining as per Appendix B of IS 8329. External bitumen coating as per Appendix C of IS 8329. Finished Internal Diameter of DI pipes is considered same as nominal diameter for hydraulic calculations. Threaded GI pipes have been considered as per IS 1239:2000. Thrust block will be provided in DI pipe line at bend. Design pressure of thrust block will 1.5 times of working pressure for given stretch.
