DESIGN OF WASTEWATER COLLECTION SYSTEM FOR TAFFOUH TOWN

Abstract

The disposal of raw wastewater without treatment creates major potential health and environmental problems. In the Hebron rural areas, the sewage facilities do not exist. People disposal sanitary waste in cesspits, latrines and open drains. The wastewater has been seeping into the ground through the overflows of the deteriorated cesspits and latrines causing serious environmental and health problems.

Taffouh like other towns in Hebron district has no wastewater collection system. People are using cesspits, latrines and septic tanks. These latrines and cesspits are deteriorating and they are in very bad condition, adding to this the increasing in water consumption and consequently increasing in wastewater production, resulting in over flows from the cesspits and excessive recharges of ground water in Taffouh town. For all these reasons, this study is conducted to design wastewater collection system for Taffouh town of the Hebron district.

The present study considered the annual population growth and their water consumption for the coming 25 years that will be the design period, along with the commercial and industrial development in the area. The necessary hydraulic calculation needed for the design of the main trunks was carried out by simple calculation.

The study shows numbers of important conclusions. Wastewater disposal in Taffouh town causes problems to people; subsequently there is a big need for design and construction of wastewater collection system. Gravity flow sanitary sewer was proposed for Taffouh to minimize the cost of construction and excavations. The proposed wastewater collection system for Taffouh town covers most of the areas of Taffouh.
