EasyCalc mobile helps water utilities and consultants to establish an initial water balance and calculate water loss performance indicators.

For many years, Non-Revenue Water (NRW) practitioners have been using the free water balance software WB-EasyCalc (can be downloaded from www.liemberger.cc) for their detailed water balance and performance indicator calculations. For such an analysis a lot of information and data is required, but often not readily available.

The app EasyCalc mobile intends to bridge the gap between “no idea about the NRW situation" and a detailed water audit using WB-EasyCalc. The app will be most useful for example in initial discussions with a water utility manager when only most basic data are readily available and the app’s default values can be used to fill the blanks. Rough estimates of potential 95% confidence intervals (+/- error margins) are integrated so that potential error range of the results can be easily understood.
