A leak was detected in a 24-inch water main from Tansa lake in the early hours of Sunday near Aarey Colony Gate 5 in Goregaon. The leak led to loss of a large quantity of water.
According to officials, the leak, which was detected two days ago, deteriorated in that time and resulted in a large quantity of water seeping out.
“It is a 15-year-old pipeline. A lot of water was wasted because the supply to Aarey Colony can not be cut off, and repair work will only start tomorrow [Monday] morning as the ward office is closed today,” said a civic official from the Vile Parle control room.
Officials also said water supply could be affected in areas between Andheri and Goregaon due to the leak and the delay in repairing it. The extent of damage and the time required for repair are yet to be ascertained.
According to civic records, in the past 15 months, there have been pipeline bursts at more than 200 places, resulting in the loss of millions of litres of potable water.
The city is currently facing a 15 per cent water cut, with the prospect of more cuts as the summer approaches.
The western suburbs and the island city will be worst hit, as only 171 days of water stocks are available in the lakes supplying water to those areas.
Most of those 200 pipeline bursts were due to the age of the pipes, as well as trenching and excavation carried out by various agencies, as well as negligence on the part of civic authorities.
The BMC supplies 3,400 million litres of water every day to Mumbai. Of this, 700 million litres is wasted due to leakage and theft — that’s the equivalent of the entire water needs of smaller cities like Pune and Nashik.
