Stop paying for water that never reaches anyone.

Non-revenue water is the gap between water that enters your building or property and water that's actually billed, used, or accounted for. In most commercial properties, a significant portion of that loss is recoverable — and most owners and facility managers have no structured data on where it's going.

What we do

  • Water loss identification using the IWA Water Balance methodology — separating apparent losses (meter errors, billing inaccuracies, unauthorised use) from real losses (physical leakage).
  • Pressure analysis to determine whether building operating pressure is driving leakage rates in irrigation, cooling, or distribution systems.
  • Minimum night flow testing to quantify active leakage during the lowest-demand period. This is one of the most reliable diagnostic tools available.
  • Leak detection coordination managing field investigation, plumber engagement, and verification.
  • Performance reporting with before-and-after loss quantification you can take to your ownership group, body corporate, or sustainability committee.

Who it's for

Commercial property managers, body corporates, facility managers, and sustainability teams with known or suspected water loss across their properties or portfolios.
