According to the civic body, of the total supply of 3,400 million litres of water, Mumbai loses around 700 million litres of water due to leakages.
In a bid to minimise water leakages from pipelines in the city, the Brihanmumbai Municipal Corporation (BMC) will carry out from October, a pilot project using high-end technology, aiming to fix the problem.
According to the civic body, of the total supply of 3,400 million litres of water, Mumbai loses around 700 million litres of water due to leakages.
"Water leakage is a major problem and we need to fix it. Through this project we will be able to identify and analyse whether the amount of water being supplied reaches the consumer without any losses (in terms of leakages). Leakages will now be determined by a detailed account of water that has finally reached the consumer," BMC's deputy municipal commissioner Dinesh Gondalia told PTI.
As water is directly supplied from the reservoir to the wards we do not have any data how much water is consumed by a particular ward. It will also help us in figuring out actual water pressure and complaints of unequal distribution of water, Gondalia said.
The local administration has awarded the project to Tata Consultancy Service (TCS) and Selcom Unity for over a period of one year. The cost of the project is Rs4.40 crore.
"The project will begin from October and would be carried out zone wise. We will see the results from the pilot project and then implement the measures in other parts of the city," he said.
According to BMC, the project will include detection of water leakage with high-end technology sensors, Ground Penetration Radars (GPRs) and mapping of underground pipelines with the aid of geographic information system (GIS).
"To detect water leakage sound sensors will be used that would send an alarm during the leakage. It will be installed at particular points in the pipeline. With the help of GPRs we will be able to detect water leakage in underground pipelines and the GIS will help map the underground utilities and complicated network of water pipelines," Gondalia explained.
With 5% and 30% water cuts for residential and commercial users respectively, the present water supply to Mumbai is 3,200 million litres a day (MLD) against the demand of 4,250 MLD.
