Why satellite leak detection has become part of the South Staffs Water’s leakage reduction plans.
In their five-year Asset Management Plan (AMP) the major UK utility company, South Staffs Water, incorporating Cambridge Water, committed to the reduction of water leakage. The target is to have a reduction of total leakage by a minimum of 15% from 2019/20 levels by 2024/25. This transformational reduction is to be achieved through a combination of prevention and active leakage control, identifying innovation in both areas to improve efficiency
The Leakage Strategy Manager from South Staffs Water turned to SUEZ for assistance and was introduced to Utilis’ satellite leak detection technology. To verify the new technology the water company conducted extensive trials and subsequently implemented the technology across two parts of their territory, a total of 6000km of distribution and trunk mains pipework. Several project parameters were measured and compared with regular leak detection without satellite aid.
The Utilis leak detection product uses satellite images that cover large areas of approximately 3,500 sq. km. They use satellites with L-band synthetic aperture radar (SAR) sensors onboard. This is because of SAR’s day/night, cloudy/clear, capability along with the L-band signal’s ability to penetrate the first few meters of earth. Using a patented algorithm, Utilis filters out the signature of drinking water and provides points of interest (POI) to the customer. The POIs are displayed in user-friendly GIS reports and direct the utility’s own field crew with the areas to search and pinpoint the previously undetected leak. This innovative technology has been adapted from the search for water on other planets, underscoring its high reliability and outstanding capability here on Earth.
Utilis offers a fresh approach that provides a non-invasive method to the problem of water network leakage. When compared with other leak detection methodologies, satellite-based leak detection has many benefits:
“We’ve carried out a very thorough analysis of Utilis/Suez’s satellite leak detection. We clearly understand the benefits it can bring in detecting leaks and we are confident in using it as part of our toolbox for reducing leakage through AMP7.” – James Curtis, Leakage Strategy Manager at South Staffs Water
South Staffs Water are looking to deploy satellite leak detection on an annual basis and ad-hoc runs for short, focussed campaigns in difficult district metered areas.
Water South Staffs Water supplies high-quality drinking water to approximately 1.3m people and approximately 35,000 commercial customers over 1,500 square km in the South Staffs region and to approximately 351,000 customers in the Cambridge region.
