ABSTRACT
The purpose of this work is to contribute to the improvement of the district's drinking water supply system in order to guarantee sufficient quantities of water by 2051. We presented the study area, made a diagnosis of the drinking water network before making a proposal for a solution. The diagnosis of the network was made by calculating the current water needs of the population using Excel software and by simulating the operation of the network on Epanet. The latter showed that the populations of the Mbour 2 district face enormous problems of access to drinking water. And these problems are due to the reduction in diameters caused by the deposition of pie in the pipes. The needs assessment allowed us to estimate future consumption at 1.098 m3/s in 2051 while drilling production is at 3.064 m3/s. From there we see the drilling can feed Mbour 2 if there is not a possible problem So it is imperative to make a limestone treatment to protect the pipes and have good drinking water. Faced with this situation. we have created a network network of Mbour 2 with the new castle R7 bis which receive fresh water from Lake Guiers in order to have a perfect dilution and also propose a renewal of the clogged pipes by choosing larger diameters. The results of the simulation with the use of the PICCOLO software showed pressure values greater than 2 bar in the Mbour 2 network which translate into a continuous availability of water without pressure drop.
