The BrihanMumbai Municipal Corporation’s (BMC) ambitious plan to monitor the distribution of all the water across the city is now in motion. The BMC’s pilot water audit project is now mapping the daily supply to three of Mumbai’s 24 administrative wards.
As of now, the daily amount of water supplied to wards B (Mandvi, Umerkhadi, Dongri), H West (Bandra, Khar, Santacruz) and T (Mulund) are being tracked by the civic body.
“Supply zones or district metering zones in these wards are clearly demarcated owing to a more systematic distribution system. Flow meters installed at the outlet of these zones give readings every hour, giving us the amount supplied to each zone and thereby the entire ward,” said Ashok Tawadia, deputy hydraulic engineer (planning and control), BMC.
The project to conduct a water audit in the city that began this year will determine the daily supply to each of the city’s administrative wards. This figure will be tallied with the daily consumption in the wards. The BMC can then determine the amount of water that is lost every day through its distribution system.
At present, civic body data shows that the island city receives 1,140 million litres, the eastern suburbs 890 million litres and the western suburbs 1,320 million litres of water every day.
“It is important that we get data on the amount of water that is supplied to each ward. We have already started compiling the daily consumption levels in the wards based on the collective monthly or quarterly bills that are sent to consumers,” said a civic official from the hydraulic engineer’s department.
The civic body, however, is still dividing the rest of the wards into zones at which the audit will be conducted and is also deciding on shifting some of its flow meters from their current locations.
“This is the trial and error stage of the project. We might have to make several changes in several areas as we go ahead. Results of the steps that we have taken will have to be checked and rectified along the way,” said the official.
