BACKGROUND
Non-revenue water (NRW) is always a challenge, but in a city like Aqaba, Jordan, which experiences a hot desert climate, it is particularly important to keep under control. In Aqaba this responsibility falls to Aqaba Water, the services company that provides water to over 250,000+ residents and visitors a year.
THE CHALLENGE
When investigating non-revenue water, Aqaba Water identified pipe bursts caused by minimum night flow pressure as a major source. On discovering these issues, Aqaba Water was unable to fix them manually, and so turned to HWM for help.
Since Aqaba Water was supplying more water into the system overnight than was being taken from it by residents, pipes were experiencing a build up of pressure that was causing them to burst.
THE SOLUTION
Aqaba Water installed 22 Pegasus 2 pressure management systems, helping them to control pressure at critical points throughout their network. With the capability to set target pressure by time, flow or a combination of both, HWM’s Pegasus solution delivers an advanced level of targeted control. All changes can be made remotely, making them immediately effective, which is especially beneficial in an emergency.
RESULTS
According to Aqaba Water, the Pegasus solution “is helping to reduce leakage, burst frequency and energy consumption. We have also found out that we can eliminate any by-passes that may compromise the integrityof the network, which can cause inaccurate measurements, unbalanced flows and pressure fluctuations.” They anticipate saving 200,000 m3 of water a year through pressure-related leak reduction, ensuring they meet customer demands and improve satisfaction.
