In a move that could save most of the 700 million litres of water that the city loses to leakages each day, the Brihanmumbai Municipal Corporation (BMC) will conduct a three-year water audit in the city.
Though it had conducted a pilot project of a similar kind, this is the first time the civic body will be conducting the audit citywide. The BMC has identified Mulund, Bhandup, Vikhroli, Ghatkopar and Kurla as areas where the project will take off this year. The rest of the city will be covered subsequently.
Currently, the civic body's water losses are based on a rough estimation. This audit will accurately identify and quantify the losses. Along with detection and repairs of water leaks, officials believe this audit will also help in equitable distribution of water to each area.
The civic body will divide the city into 27 district metering zones, the quantity of water supply to which will be measured by installing flow meters in each zone. These zones will then be sub-divided into district metering areas, with 4,000-5,000 connections each. Each of these connections will have a meter, which will then record how much water each household consumes.
After the final figures come in, the BMC will conduct leak detection checks in these areas.
