The purpose of a water distribution system is to provide an adequate and reliable supply of safe drinking water to its users. Operation and maintenance are those activities needed to continuously fulfil this goal.
For this purpose, the closer analysis of the performance indicators of a water supply service is fundamental for a well-managed network, as well as the water resources it requires. Today, it is the most efficient way to identify failures within a network and then neutralize them.
This article aims to analyze the Performance Indicators of the Dar Bouazza’s Water Supply System, associated to pressure stage 115, located about 20 km west of Casablanca.
The work focused on the analyse of the following performance indicators the minimum night flow, the yield, the Percentage losses, the linear leakage index, Leaks per sector, the linear leaks index, the linear consumption index and the age of water pipes. A multi-criteria analysis was achieved to determine the pressure sector’s risk levels and propose solutions to neutralize its failures.
In its current state, the water network requires the implementation of an action plan which aims to reduce the volume of water losses. Here are the modifications that have been proposed for the concerned area:
Leak detection and repair;
Finer sectorization of the network;
Water metering improvement;
Partial system renewal.
Developing an action plan to reduce the water hammer’s effects.
Regular update of the network plans following its renewal and extension.
