ASTERRA Recover uses satellite imagery to cover large areas and quickly narrow down the regions that contain probable leaks. How do we do this? Specifically, L-band synthetic aperture radar (SAR) sensors are used for their day/night, cloudy/clear capabilities along with the ability to penetrate the first few meters of earth. Using a patented algorithm, Recover can filter out the signature of drinking water and provide these zones to the customer. They are then displayed in user-friendly GIS reports and direct the utility’s preferred field crew to search within the zones to pinpoint the exact leak location. This technology has been adapted from the search for water on other planets, underscoring its innovative and outstanding capability here on Earth. Recover offers a fresh approach and non-invasive method to the problem of urban water leakage. When compared with other leak detection methodologies, satellite-based leak detection identifies more leaks per day, saving you water, time, money, and energy. Utilis developed the ASTERRA products to use satellite-based synthetic aperture radar (SAR) to locate and analyze moisture accumulating underground. Our products include MasterPlan for pipe deficiency assessment; Recover for leak detection; and EarthWorks for ground infrastructure assessment. ASTERRA pierces clouds, forests, and even pavement to assess entire systems quickly and efficiently. Our first commercial use was in 2016. Since then, 36,000 leaks have been verified, saving 9,200 million gallons of drinkable water and 21,800 MWH of energy every year, savings that continually grow.
