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 economical point of view. After that we tackle a system of protection against hammer water, it consists of air tank for the pumping pipe, its role is 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..
