DESIGN OF WASTEWATER COLLECTION SYSTEM FOR HALHOUL CITY

Abstract

Currently,there are no public wastewater collection and treatment facilities servicing city .Wastewater from individual residential houses is discharged directly into cesspits,allowing the wastewater to seep into the surrounding soil and percolate into the undelying aquifer .In many areas,these subsurface cesspits require frequent cleaning and replacement at a considerable cost. The municipilty of Halhoul is planning to built sewer network and wastewater treatment facilities . In this study ,an attempt is made to investigate and evaluate wastewater cololection system along with conceptual design that are suitable for Halhoul community ,cost effective and easy to operate and maintain .The design were made for the main trunk making into consideration the population growth for Halhoul City and the future water consumption for the coming 25 years that is the design period for the project . The analysis and calculation shows that the proposed wastewater collection system can serve most of the area in Halhoul city with agravity system except for two areas where pumping station is required
