Distribution Network Maintenance

WASCO is committed to maintaining a reliable water distribution network by promptly repairing pipeline bursts and leaks reported by customers or identified through routine inspections.

In addition to reactive maintenance, WASCO employs specialised leak detection teams that regularly inspect the water network to identify hidden leaks and minimise water losses. To improve the efficiency of these efforts, the Company is progressively dividing the distribution network into hydraulically discrete zones known as District Metered Areas (DMAs).

Each DMA is designed to have a controlled water inflow, which is continuously measured and monitored. By comparing the volume of water entering a DMA with the volume of billed consumption, WASCO can accurately identify areas with high water losses and prioritise maintenance activities.

Benefits of District Metered Areas (DMAs)

• Reduce Non-Revenue Water (NRW) by accurately measuring water losses within each zone.
• Identify physical and commercial losses through continuous flow and pressure monitoring.
• Prioritise leak detection and pipeline maintenance in areas with the highest water losses.
• Detect new leaks and pipe bursts quickly, reducing response times from months to days—or even hours.
• Improve the detection of illegal connections and water theft, enabling timely corrective action.

Through proactive maintenance, advanced monitoring technologies, and continuous network improvements, WASCO is working to enhance service reliability, conserve water resources, and provide better service to its customers.
