Adduction à partir de la station de dessalement de Honaine w. Tlemcen pour le renforcement en AEP de 18 communes de la w.Sidi Belabes

Abstract

The memorandum entitled "Adduction from the Honaine desalination plant in Tlemcen province to reinforce the drinking water supply of 18 municipalities in Sidi Bel Abbès province" is a project that was carried out for the benefit of Sidi Bel Abbès province, which has been suffering from a water deficit for several years. The managers of the Honaine seawater desalination resource (Tlemcen province) have decided to allocate a quota of 100,000 m3/day to 18 municipalities in Sidi Bel Abbès province by means of a transfer (adduction) over a total length of (30 108) ml. We had the opportunity to study several options through a techno-economic study that highlighted an ideal and economical route. The route in question is divided into 3 sections: 2 gravity sections and 1 pumping section. The linear works include 2 reservoirs of 20,000 m3 each and a pumping station, where we had to dimension the adduction pipes, pumping station, reservoirs, balance chimney and carry out a study for protection against water hammer. In the end, a study of the project cost was necessary, which allowed us to estimate the price of a meter of water at 10.66 DA/m3, taking into account all investment and operating costs.
