  1. An-Najah National University Faculty of Engineering Civil Engineering Department Design of Wastewater Collection System of Tubas City Prepared by: HibaHassoun & 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 18000 people in 2007. 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 icludingquestion about

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

  8. Manhole information

  9. Sewer information

  10. Outlet information

  11. Run the network and get the results Velocity

  12. Cover

  13. Conclusions • 211 manholes • 211 pipes • 2 outlets • Total flow for manholes varies between 3553(l/d) to 926680(l/d) • All pipes have the same diameter 200mm (8 inch) • Velocity varies between (.5-3.74)m/s

  14. Thank you
