WaterBalanceCalc
A free implementation of the IWA standard water balance with uncertainty, performance indicators, cost of losses and carbon. Methodology after the IWA Water Loss Specialist Group and the WB/WCB-EasyCalc lineage by Roland Liemberger and friends.
Free to use, always. Results are only as good as the data entered — verify real losses with field measurements before acting on them.
