  2. The Objective of the Project: • 1- The main objective of this project is to design the water • distribution network for Noorshams with the aid of WATERCAD. • 2- Solve the problem of quality of water.

  3. Study Area • Noorshams is located to the east of the city of Tulkarem. • Noorshams rises about 150 m above mean sea level. • - The area of Noorshams is about 250 dunums. • - Noorshams has a population of about 7063 inhabitants.

  4. Questionnaire Analysis:

  5. WaterCad WaterCAD is a powerful yet easy to use program that helps engineers design and analyze complex, pressurized piping systems. Advantages : 1- WaterCAD will help you to analyze multiple time-variable demands at any junction node. 2- WaterCAD provides solutions to model flow valves, pressure reducing valves, pressure sustaining valves, pressure breaking valves and throttle control valves.

  6. Equation Used in WaterCAD - Hazen-Williams. Hl = 162.5(Q/C)1.852D-4.87L - Darcy – weisbach. Hf = F(L/D)(V2/2g) - Manning. Hf = F(L/D)(V2/2g)

  7. Population : The population of  the Noorshams by the Central Statisticsin year 2012 is estimated 7063. To calculate the growth rate through the equation:-- Pf = 10095 Pp = 7063 i= 1.9%, 1.2%, 1% n = 10, 10, 5 From these information the population in 2037 is estimated 10095.

  8. Demand: • The consumption in year 2012 from quastionnaire 90 (L/C.d). • We increased the consumption in first ten years 4 (L/C.d), and 2 (L/C,d) for the second ten years, 1 (L/C,d) for the last years.

  9. Design Criteria: • Head pressure should be not more than 100 m, and not less than 10m. • Maximum velocity should not be greater than 3m/sec, and minimum velocity should not be less than 0.1m/sec.

  10. The Results: • The results is acceptable the design criteria, and these result as the following: • The Pressure: • All the pressure in the pipes is acceptable which range between (1 bar 5.5 bar). • The velocity: • Most of the velocities are within range, but some nodes in the end of the network are low(0.01m/s), but in general the velocity is acceptable.
