Etude et dimensionnement du projet de renforcement du system d’alimentation en eau potable de la commune de TAMAZOURAH a partit du forage d’AGHBAL

Abstract

Drinking water is an essential resource for socio-economic development and improving living conditions. In this context, the municipality of Tamazourah faces a continuous increase in demand for drinking water, necessitating the strengthening of its supply system to guarantee reliable and sustainable distribution. This thesis focuses on the study and design of the project to strengthen the drinking water supply system for the municipality of Tamazourah, drawing from the Aghbal borehole. The main objective is to propose a technical and economic solution to meet the current and future needs of the population. The study assessed the municipality's water needs and determined the dimensions of the infrastructure required for transport and distribution. The project includes a 4,600 m long, 160 mm diameter delivery pipeline, ensuring the conveyance of water to a 2,000 m3 reservoir. The AGHBAL borehole has a depth of 140 m and an exploitable flow rate of 14 l/s. Hydraulic calculations indicated a pressure of 1.92 bar at the reservoir. The economic study estimated the overall cost of the project at 67,950,000 DA, confirming its feasibility despite the necessary investment. The results obtained demonstrate that the AGHBAL borehole is an optimal solution for strengthening the drinking water supply to the municipality. This project ensures greater water security, improves the quality of public service, and guarantees a sustainable supply of drinking water for the population of TAMAZOURAH.
