ANALYSIS AND DESIGN OF WATER DISTRIBUTION NETWORK AND WASTEWATER COLLECTION SYSTEM FOR AL-SHOYOUKH TOWN

Abstract

There is no wastewater collection system at present in Al-Shoyoukh town. The sewage from residential and public buildings in the area is drained to cesspits. These have become clogged with time and require frequent emptying. The continued use of cesspits with the increase in population will cause environmental and health problem, and may create contamination of the underground water aquifer. Furthermore, emptying cesspools constitutes an offensive odor nuisance to the population. On the other hand, emptying the vacuum trunks in the nearly wadi causes negative impacts on the visual landscape. In reference to above description of the existing situation, there is a clear need of project in order to improve the sanitary level in Al-Shoyoukh town. The first step is serving the town with wastewater collection system, which is one of the main objectives of this project.

Al-Shoyoukh town also faces big problems in water supply and water services due to population growth. Hence, the water distribution network is not servicing all the areas in the town, and many pipes are old. The people in the town depend mainly on water coming through the network and on water tanking and constructed cisterns for water supply. In view of this bad condition, the need for water supply scheme that will supply the entire area of Al-Shoyoukh town with water requirements become pressing, and subsequently this work was conducted to study and evaluate the present situation and redesign of the existing water distribution network using water-cad software.

The present study considered the annual population growth, their water demand and wastewater quantity for the coming 25 years that will be the design period, along with the commercial and industrial development in the area. The hydraulic calculation needed for the design of water pipelines will be carried out using Water Cad software, and design of the main and sub-main wastewater links will be determined using Sewer Cad software.

By the end of this project, a complete design for water distribution network and waste water collection system for Al-Shoyoukh town will be ready along with bill of quantities, cost estimate, and the suggested phases of construction.
