The drinking water transfer is ensured by conduits from the stopping (El Agrêm ) towards th concerned zone (Taher wilaya of Jijel ), for this we have collected all data relating to the zone of study by taking account of all the methods of calculation of the requirements of water. wwill examine, after the presentation of our zone of study and the estimation of its needs in water, the conditions in which will have to be established our mixed adduction (gravitaryrepression) from both a technical and economic point of view, those two aspects being, in fact, bound together. In the repression pipe, waters are raised by pumping plants; we will study their conditions of establishment of retake plants of the adduction chain. We will tacklthereafter, a protection means of the repression pipes, in particular, against a transitory phenomenon called: the water hammer.
