Starting point

Non-revenue water sat above the operator's target with no reliable way to rank zones. Leak crews were dispatched on customer complaints, and pressure transients went unrecorded.

We stopped searching zones and started searching streets.
Head of Network Operations

What we deployed

  • Battery-powered flow and pressure loggers with NB-IoT backhaul
  • Minimum night flow analytics with per-DMA leakage ranking
  • Transient detection to flag valve and pump operations damaging the network
  • Work-order integration so the top-ranked DMAs drive the weekly crew plan

What changed

  • Weekly leak programme built from ranked night-flow data
  • Pressure management reduced burst frequency on ageing mains
  • Regulatory reporting drawn from one validated dataset
