Design of Wastewater Collection System
of Tubas City
Prepared by: Hiba Hassoun & Zeinab Abu-Mohsen
Supervisor: Dr. Mohammad N. Almasri

2. Introduction There is many advantages from having a wastewater
Collection system …….. Conservation of environment, reduce pollution of groundwater
Tubas city dose not have infrastructure for the wastewater ………….. They get rid the wastewater by using cesspits
The solution is construction of wastewater collection network accompanied with wastewater treatment plant

3. Objectives
Understand the situation of the collection and disposal of wastewater in Tubas City.
Design a wastewater collection system for a portion of Tubas City using sewerCAD software.

4. Study Area
Location: Tubas City located northern part of the West Bank about 20 km northeast of Nablus ,24 km southeast of Jenin

5. Population:
the town of Tubas inhabited by about people in
Topography & Climate:
The height varies in tubas and change from 670m to 290m , its about 555m above mean sea level.
The climate of Tubas is moderate in summer and winter, the averge annual rainfall is about 414mm

6. Methodology:
Collect the data related to the study area…….contour map, population ,daily consumption of water , AutoCAD data.
Collect information through questionnaire icluding question about

12. Calculate the load of each manholes.
Design wastewater collection system using SewarCAD
Drawing manholes & connect it with sewers
Input data
constrain information

13. Manhole information

14. Sewer information

15. Outlet information

16. Run the network and get the results
Velocity

17. Cover

18. Conclusions 211 manholes 211 pipes 2 outlets
Total flow for manholes varies between 3553(l/d) to (l/d)
All pipes have the same diameter 200mm (8 inch )
Velocity varies between ( )m/s
