Enabling sustainable Non-Revenue Water management in the Czech Republic

We developed a Non-Revenue Water (NRW) reduction methodology for the Czech Republic, the most important part of which was the implementation of our Leakage Monitor. The monitor has effectively helped to manage leakages in the water distribution networks and maintain them at stable and economically optimal levels.

Severočeské Water and Sewerage Company (SCVK a.s.) operates the largest regional water supply system and distribution network in nearly 400 settlements in the Czech Republic. However, many of the water distribution networks suffered from high leakage levels – to the tune of 20-40%.

In close cooperation with SCVK a.s., we developed a methodology which catered to their specific requirements. One of the most important parts of the NRW reduction strategy was the implementation of our Leakage Monitor. This implementation began in 2009 as a part of the Teplice WSS Master Plan and today covers the six most important cities in the region.

The Leakage Monitor is a software and implementation tool for complex data collection, leakage and NRW evaluation in District Metering Areas (DMAs). It’s used for daily optimisation of leakage management, pipe failure detection and network repair strategy developments.

The NRW reduction strategy resulted in significant savings with respect to water leakages as well as operational costs.
