Diagnostic et réhabilitation du système d'alimentation en eau potable de la ville de chechar (w. Khenchela)

Abstract

Diagnosis of a drinking water network is a study that includes the hydraulic and physical analysis of the current network. Our work consists of conducting a rehabilitation study of the drinking water supply system for the city of Chechar in the Wilaya of Khenchela, which involves identifying the failures in the distribution system as well as the storage facilities (reservoirs) and verifying the capacity of the existing network to convey the necessary flows by the study horizon (2048). Since this system cannot meet the needs by the study horizon (2048), our objective is to our objective is to carry out a rehabilitation study of the system to improve the drinking water supply to the city. These include designing a network for areas that do not have one, renovating the distribution network (PVC conduits), and implementing a zoning system to meet the future water needs of our community in terms of flow and pressure. This also involves determining the location of accessories and measuring devices. Additionally, we have proposed the construction of a 3000 m3 reservoir to meet the demand. Finally, we have presented pipeline installation techniques and prepared a cost estimate for our project.
