Abstract :

In accordance with Sustainable Development “Goal Number 6 (SDG 6)”, the main objective of the Democratic Republic of Congo (DRC) is to ensure universal and equitable access to drinking water for all by 2030. The town of Kenge, like other towns in the DRC, is currently facing enormous difficulties in accessing drinking water due to a lack of energy. The aim of this study is to assess the supply of drinking water to the town of Kenge and the level of water service in relation to actual demand, based on the total installed power of REGIDESO S.A./Kenge’s generating sets and motor-driven pumps. This approach makes it possible to calculate daily production by considering the scenarios of the energy demand of the motor pump sets satisfied by the generating set. The results showed that, in a scenario where the genset operates at 60% of its energy demand, water production is 120 m³ per hour, giving an average of 960 m³ for the 8-hour operating time required by REGIDESO S.A./Kenge. These figures are halved during the rainy season, to 480 m³ in a scenario of low demand for water by the population. This production is well below the actual daily drinking water requirement of the population of the town of Kenge, which is estimated at 7076 m³ for a population of 353810. Furthermore, the drinking water supply rate is 14% and 7% respectively for the two operating scenarios (high and low water demand).
