With rains playing truant in catchment areas, Mumbai may have to face water cuts. But there is no need to panic yet, claim civic officials, saying they will review the situation at the end of the month.
At present, the water stock available in the seven lakes that supply water to the city is sufficient for 237 days compared to last year’s 327.
While two lakes had crossed their maximum storage capacity by August 10 in 2014, this year, not a single lake has reached its maximum supply level.
At present, the stock of water available is 8.9 lakh million litres. Last year, it was 12.2 lakh million litres as on August 10.
According to the data available with the Brihanmumbai Municipal Corporation (BMC), this is second-lowest water stock available by August 10 in the past five years, with the lowest being 7.42 lakh million litres in 2012.
Officials said low rainfall in catchment areas of lakes was worrying.
As a precautionary measure, civic officials have started planning steps to ensure year-long supply to the city.
“The catchment areas usually receive heavy rain by July-end and early August. This year, we will have to plan the supply carefully as the weather department has predicted less rainfall in the catchments for the next few weeks,” said a civic official.
The catchment areas received less than 10-12mm rain from Sunday morning to Monday morning.
Civic officials said they will wait for some time to take further steps.
The lakes need to have water stock for 304 days by October 1, they said. If the dry spell continues, the BMC may have to introduce water cuts.
“We have about 61% of stock available at present. We will review the situation again by the end of the month,” said Ashok Tawadia, chief engineer, hydraulic department, BMC.
