Gutermann water loss detection — acoustic sensor installation on distribution network

Water Loss Detection

WATER PLATFORM

Global water losses reached 126 billion cubic meters in 2019 — approximately 40 billion USD in financial impact. Cities lose between 5% and 80% of their distributed volume. Non-revenue water is not a minor inefficiency — it is a systemic failure that Klarwin addresses with proven, scalable technology.

Through an exclusive partnership with Gutermann — world leader in acoustic leak detection — Klarwin delivers integrated NRW solutions for water distribution operators: permanent monitoring, precise localization, and real-time network intelligence.

Litres of drinking water lost through a single average crack.

The estimate is calculated for a 3 cm × 1.5 mm crack on a DN160 municipal water pipe at a service pressure of ≈4 bar, using the classical orifice discharge equation (Cd ≈ 0.62). The resulting loss is approximately 2,850 litres/hour.

In a single day, the loss can reach 68 m³ of water. In a year, a single undetected leak can mean approximately 24.9 million litres of drinking water lost.

Through Klarwin detection and monitoring technologies, hidden losses can be identified quickly, before their impact becomes major.
