The philosophy of Liemberger & Partners to provide the best possible NRW advice and NRW management services has not changed and therefore the much acclaimed multi-lingual water balance and water loss performance indicator software WB-EasyCalc is still freely available.

The first version of WB-EasyCalc was designed in 2006 to help water utilities and consultants properly apply the IWA Water Loss Specialist Group Methodology. During the last 10 years it has become the preferred NRW analysis tool for water utilities around the world.

To celebrate its 10th anniversary, version 5 has been released in August 2016 and after correction of a few bugs it was re-named to version 6 in 2019. Please download the latest version (6.17, August 2021) of WB-EasyCalc.
