Diagnosis and Solution of the Drinking Water Supply Network of the Municipality of Diembéring

Diembéring, a municipality in Ziguinchor region (with 21 villages) has a considerable deficit in drinking water supply to the population. And yet the sources of supply are not lacking. In this part of the region, the quality water supply rate remains very low. This article follows a process of collection, analysis and exploitation of data (hydrogeological, geomorphological, geological) obtained at the site level. Then, an evaluation of the population compared to the horizon of 2041 is carried out, which allows the estimation of the evolution of the necessary drinking water needs. The geographical and hydraulic criteria allowed us to subdivide the system into two very distinct networks: two multi-village adduction systems (SAEMV1 and SAEMV2) composed of two water towers of 200 m³ each for a HMT = 45 m, serving standpipes [1]. So, for [2]: ？ SAEMV1 (14 villages): the population is estimated at 10,400 inhabitants in 2041 and water needs are estimated at 365.849 m³/s; ？ SAEMV2 (07 villages): population is estimated at 38,354 inhabitants in 2041 and drinking water needs are estimated at 1,216.537 m³/s. As designed, this article is in line with the strategy that aims to promote access to drinking water as a means of reducing poverty [3].
