ANALYTICAL STUDY OF THE WATER QUALITY FOR THE DRINKING WATER NETWORKS IN BECHAR CITY

The study carried out involves an evaluation of the physico-chemical parameters of drinking water networks in Bechar city (Algeria). In this work we have characterized the quality of drinking water, investigated the main sources of water pollution and proposed solutions to this problem. Today, the water consumer in Bechar city enjoys an aftertaste in drinking water, despite its treatment upstream of the dam. The installation of the dam began in October in 968, the drinking water supply system of the town of Bechar was carried out between 1978 and 1980, and the dam was inaugurated in May 1981. This work was initiated to better understand the quality of drinking water. The quality of drinking water must be checked upstream (sources of water) until downstream (consumer), it can also be degraded during its storage and passage through the distribution of drinking water networks. Contamination can come from the network itself. The results found show that almost all of the parameters analyzed comply with both national and international drinking water regulations. To this end, we have concluded that the supply of drinking water to the city of Bechar is subject to several constraints such as the degradation of drinking water supply networks and the aging of reservoirs.
