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

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.​
