Design of Wastewater Collection System
of Tubas City
Prepared by: Hiba Hassoun & Zeinab Abu-Mohsen
Supervisor: Dr. Mohammad N. Almasri
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
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.
Study Area Location: Tubas City located northern part of the West Bank about 20 km northeast of Nablus ,24 km southeast of Jenin
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
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
Calculate the load of each manholes.
Design wastewater collection system using SewarCADDrawing manholes & connect it with sewersInput data• constrain information
Manhole information
Sewer information
Outlet information
Run the network and get the results
