Etude de systeme d'alimentation en eau potable de la ville de Mahelma (w. Alger)

Abstract

The proposed théme is part of project of drinking water supply (DWS) approved by SEAAL on strengthening supply of complex hydraulic « SAHEL » this is to strengthen the existing supply network of commons MAHELMA and RAHMANIA. After presenting our study area and estimate water needs of the city by the year 2045, we calculate the resource gap to provide the necessary amount of water consumed. The chosen conduit is seen from a technical and economic point of view in parallel with the existing pipe by using the new approach of operating costs and investments to the size and the water are identified by the new pumping station to be built at the site of hydraulic complex « SAHEL », we study the pump and the dimensions required for this station. We will etablish the good management methodologies and operation of the pumping station, and the calculation of operating pressure in the distribution network by simulating the way of network operation during the day.
