Etude des transferts d'eau par raccordement au système MAO pour l'alimentation en eau potable de Sept agglomerations de la Wilaya de Mostaganem

Abstract

Through this study, we intend to design a system to transfer water from a reservoir which is supplied by MAO system, for providing drinking water to seven agglomerations of the region of Mostaganem, for the 2040 projection. It is analysed. After the presentation of our study area and the estimation of its needs in water, we examine the conditions in which our combined pipe(pumping – heady gravitational ) has to be established from both a technical and economic point of view. After we tackle two systems of protection against hammer water, the first one consists in air tank for the pumping pipe, and the second one is to project a valve with slow closing to attenuate the phenomenon of water hammer. Finally, we study the cost of the project by evaluating all the works necessary to achieve our project: trenching, excavation, laying and protection of pipes and the accessories used, recovery etc..
