Heba Abu Jaber

2. The importance of water distribution network
To facilitate the process of providing consumers with clean water.
Provide quantity that suit their needs and control the quality of this water because the presence of this network ensure unpolluted water and access to consumers with best quality.

3. Objectives Design a service reservoir for Misilyah village.
Design the water distribution network for the village of Misilyah using EPANET

4. Study area Geographical Location
Misilyah is a Palestinian village in the West Bank, located 14 km in the South-east of Jenin city in the north of the West bank. 

5. Geographical location

6. Climate : Hot and dry in summer and cool and rainy in winter
The temperature of the air is moderate
it has an average of 20.3 C

7. Rainfall
Rainfall = 52.8 mm

8. Methodology: 1- collecting information and reliable data.
2- Drawing network using AutoCAD.

9. Drawing the Network

10. 3- Convert the network into EPANET.
4- Calculations using both Excel & GIS

11. Population using Excel

12. Conversion
into
GIS

13. Thiessen Polygon Areas

14. 5- Make EPANET run.
6- Problems such : -ve pressures , having nodes pressure head which less than acceptable(20m).
7- Solving above problems & make successful run.

15. Design Constrains:
1- Velocities range (0.3 – 2) m/s.
2- Pressure head above 20m.

16. - ve pressure problem

17. Changing Nodes Diameters
Modified Dia 78
50.8
76.2 79
25.4

18. Final Shape

20. Results: 1- Pipes diameters such : 6`` & (1-4)``.
2- Velocities & pressures are both within the acceptable range.
