After heavy rainfall this month, the existing water supply is at 7.93 lakh million litres and the BMC has removed the 20 per cent water cut it had imposed in the city since last year. The decision was announced during the standing committee meeting on Wednesday.
Operations to restore normal water supply of 3750 MLD was initiated on Wednesday and will be effective from Thursday. The BMC’s current water stock is 64 per cent higher than the average water supply figures in the last 10 years.
The BMC needs 14.37 lakh MLD water by October 1. With two months of rainfall still to go, 54.79 per cent of the total capacity of the seven lakes has been filled. On July 20, the total useful content in the seven lakes was at 7,93,051 MLD which equals 167 days of water supply.
Additional Municipal Commissioner Sanjay Mukherjee said that July witnessed substantially heavier rainfall than the average rainfall in the past 10 years.
“Although the India Meteorological Department (IMD) had predicted above average rainfall this year, the rainfall last month in Tansa, Modak and Bhatsa, was only 50 per cent of the average of the rainfall in the past 10 years and 25 per cent in Upper Vaitarna and Middle Vaitarna. But the rainfall in catchment areas in July was heavy and 33 per cent more than the average,” he said.
Mukherjee added that the water cut was revoked with the hope that the rainfall would continue over the next couple of months. He said all orders related to water cuts, imposed by the municipal commissioner last year, was also revoked.
Officials in the hydraulic engineering department said that removing the water cut was preferable to wasting water after the lakes started overflowing. “Tulsi has started overflowing and Modak Sagar will soon too. Even Bhatsa is filling at a fast pace. Considering the current pace at which the lake levels are rising, we can utilise the excess water and remove the water cut. If required, we can bring the water cut back later,” said a senior civic official.
On July 20 last year, Bhatsa had a supply of 70,108 MLD and this year, the lake already has 3.98 lakh MLD of useful content.
