Abstract

The proposed theme is part of a 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 2044,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 investment to the size and the waters 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 establish methodologies of good management and operation of the pumping station, and means of protection against water hammer and corrosion of the discharge. We will finish our work by the methods of implementation, execution and site security.
