Design of Wastewater Collection System For Nahaleen Village

Abstract

The aim of this study is to design a wastewater collection system for Nahaleen Village , this Village are suffered from shortage of existing Infrastructure, such as wastewater collection system. Therefore; the dispose wastewater without any treatment, will cause danger to human health, unacceptable damage to the natural environment, and water resources (surface and underground water). To design Wastewater collection we do preliminary studies: first, Prepare Contour Map and Geotechnical Investigation (soil type) and detail Map of the area showing street. Second, known water supply and consumption studies and identification of the area. Third, collected all the information about the village such as the number of its residents, then after we divided the area and we named the streets and determined the areas covered by the network, and then we named all the data such as manholes, pipes ... etc., then the flow quantity for each pipe was calculated to design a sewage network. After finishing our project we expect to design a wastewater collection system , that provide a good sanitary environmental condition of Nahaleen protecting public health ,dispose the human excrete to a safe place by a safe and protective means , to dispose of all liquid waste from community to a proper place for preventing a favorable condition of mosquito breeding ,fly developing or bacteria growing , to transport liquid to wastewater treatment plant so as not danger or land to get of polluted where it is disposed off . The present study considered the annual population growth and their water consumption for the coming 25 years that will be the design period the necessary hydrulic calculation needed for the design of the main trunks was carried out by simple calculation.
