For all these reasons, this study is conducted to design wastewater collection system for Idhna Town of the Hebron district.
The present study considered the annual population growth (3.5) and their water consumption for the coming 25 years 120 l/d that will be the design period, along with the commercial and industrial development in the area .The necessary hydraulic calculation need for the design of the main trunk was carried out by simple calculation.
The results of the present study show that the waste collection system for Idhna town will cover all the area of the town , the collection system consist of four line as main line and seven submain , nine line designed by gravity and two line must used pump because of its outfall setuation near the .
