Non revenue water reduction project applied to the “An Dien – An Phu”

MI was selected by the Water Company of Ho Chi Minh to carry out a diagnosis of non revenue water and implement immediate solutions in primary areas of the city (40% of non revenue water).

The pilot area included 40 km of network and more than 20,000 inhabitants. The percentage of non revenue water had increased over 20% during the previous 2 years without SAWACO could have clearly identified the causes.

The implementation of the non revenue water reduction program ensured an improvement of the effectiveness of SAWACO through training sessions and technology transfer.
