Economic impacts resulting from reduction of leaks—i.e. the decrease in Non-Revenue Water. Savings have been estimated by the water utility as a percentage of the water saved.
For every validation trial the leakage reduction was estimated, which can be considered as a reduction in Non-Revenue Water. The KPI was calculated basing on the cost of pumping the energy expended (kWh/m3 pumped) and water treatment cost for the water saved.
