ASSESSMENT OF HYDRAULIC PERFORMANCE AND INEQUALITIES IN ACCESS TO THE YOPOUGON-KOWEIT DRINKING WATER SUPPLY NETWORK (ABIDJAN, COTE DIVOIRE)

The drinking water supply in the Yopougon-Koweït neighborhood faces challenges in terms of accessibility and performance of the drinking water supply network. This study aims to evaluate the hydraulic performance of the drinking water supply network in the Yopougon-Koweït neighborhood in Abidjan. The methodological approach is based on data relating to water production and water demand from the population, collected by SODECI in 2010, 2015, and 2022. The results reveal a significant but incomplete improvement in access to drinking water. The access rate rose from 39% to 68% between 2015 and 2022. Analysis of the state of the network highlights its aging and poor hydraulic performance, despite progress. The network's efficiency improved from 32% to 62%. Linear losses have been reduced from 88 to 28 m³/day/km. However, the network has a very heterogeneous and fluctuating pressure profile, ranging from -1.25 to 32.1 mWC. This situation creates inequalities in access between sub-neighborhoods.
