Rehabilitation of Drinking Water System: Optimization by Phasing of Installation
- 26 Downloads
The rehabilitation of drinking water supply pipes is an unavoidable dilemma in the life of a drinking water system. Thus, rehabilitation is defined as the replacement of a section of drinking water pipe due its failure (breakage, leakage, clogging by the limestone or planting roots) or for reaching the end of its lifecycle. Network rehabilitation consists of the replacement of pipes with the same or larger diameter.
This case study highlights the phasing of the rehabilitation of drinking water distribution pipe in two localities Bouderbala and Souk Elgour (PROVINCE OF ELHAJEB, KINGDOM OF MOROCCO).
This study summarizes the result of a partial rehabilitation and its impact on the yield, distribution of drinking water and on the population since clean water in sufficient quantities becomes a more pressing problem. Intangible improvements have been observed. Indeed, before the total rehabilitation of the network, the hydraulic yield is resented unsatisfactory and below the inspirations of the operator, but a clear improvement as regards the yields by sector also the leaks are concentrated in the non-rehabilitated areas which facilitates the repair intervention and a satisfaction of population’s demand.
In conclusion, the total rehabilitation will be the ultimate solution to improve the yield and to satisfy population’s demand in clean water (quantity, quality, pressure).
