Serving more than 40,000 residents southwest of Dallas, the City of Duncanville faced growing water loss challenges across its aging water infrastructure. Non-revenue water had risen from 5–8% to as high as 30%, while rocky soil made many leaks difficult to detect because water often traveled through fissures and drained away without surfacing.
By partnering with ASTERRA and deploying satellite-based leak detection using L-Band Synthetic Aperture Radar (SAR), Duncanville was able to scan its 240-mile water distribution system and pinpoint underground potable water leaks that traditional methods could miss.
The Impact:
- 80 leaks identified in just 15 days
- 99% of leaks were non-surfacing
- 10 main line leaks found
- More than $350,000 in cost savings
- More than 102 million gallons of potable water saved
- Field crews shifted from reactive repairs to proactive, prioritized leak repair work
Through a proactive, data-driven approach, Duncanville improved its ability to identify hidden real water loss, optimize limited staff resources, reduce operational costs, and protect valuable water supplies.
