Water utilities worldwide lose 20-40% of treated water through underground leaks — known as Non-Revenue Water (NRW). Your mission: deploy smart sensors to detect and repair hidden leaks before too much water is lost.
Your Tools
🔊
Acoustic Sensor — Listens for leak vibrations. Shows how many leaks are in the 8 surrounding cells. Like Minesweeper!
➡
Pressure Monitor — Detects pressure drops. Shows an arrow pointing toward the nearest leak.
📏
Flow Meter — Measures flow anomalies. Shows the exact distance (in cells) to the nearest leak.
🔧
Repair Crew — Send a crew to fix a leak. Costs money even if no leak is found, so be strategic!
Tips
Start with cheap Acoustic Sensors to narrow down areas
Use Pressure Monitors to find the direction of leaks
Flow Meters give precise distances — use them to pinpoint
Watch your budget and the water loss meter!
Fix all leaks before water loss reaches 100%

If you run out of budget or time, unfound leaks are revealed so you can learn
Why It Matters
Smart water networks use exactly these sensor technologies to find real leaks. Acoustic listening devices, pressure sensors, and flow meters help utilities save millions of gallons of water every day.
