Abstract
The main aim of this study was to assess the efficiency and performance of a drinking water supply (DWS) network for an urban cluster at Tlemcen Algeria. A three-stage quality management approach was employed to identify the strengths and weaknesses in the control of water service from an operational perspective. Specifically, quality indicators were measured and differences were quantified in assessing the state of the water supply network; managers in the organization as well as subscribers were surveyed; and finally corrective and preventive measures were then taken to ensure continuous operation and sustainability of the service. The results showed that the DWS in the urban group of Tlemcen was characterized by an insufficient production which could not cover the actual needs. Water was provided to the districts twice per week only for a few hours. Adding to this, there was a 50% water loss during transport as a consequence of steel pipeline corrosion, poor quality workmanship, and a lack of proper maintenance and renewal of the conduits.
