Chennai Metropolitan Water Supply and Sewerage Board has started work to convey 350 million cubic feet of water from Sikkarayapuram quarries to Chembarambakkam treatment plant. The 3.5-km pipeline will help supply 30 million litres of water daily. Minister K.N. recommended the project to store rainwater in quarries and mitigate inundation. The Water Resources Department will also carry out improvement works at a cost of ₹45 crore. 1,034.11 mld of water is currently supplied to domestic consumers.
The Chennai Metropolitan Water Supply and Sewerage Board had started work on Saturday, September 9, 2023, to convey water stored in abandoned quarries at Sikkarayapuram near Mangadu to Chembarambakkam treatment plant for drinking water supply to the city.
The water would be pumped through three high powered motors and two diesel generators and conveyed through a 3.5-km long pipeline from the quarries to the treatment plant.
Nearly 350 million cubic feet of water (mcft) is stored in about 5 quarriers.
It may be recalled that the water from these quarries were initially used during the 2019 drought and they remain as buffer sources for Chennai to offset gap between demand and supply.
Work is in progress to create infrastructure using ductile iron and high density polyethylene pipes to transmit water.
A press release said the work is being carried out following the recommendations of Minister for Municipal Administration K.N. during a recent review meeting.
The network would help convey about 30 million litres of water daily (mld) to the plant to be treated and distributed to various parts falling under Greater Chennai Corporation.
The Opposition Congress demanded that the government open the Gandhi Vatika Museum, depicting Mahatma Gandhi’s legacy and freedom struggle, built at a cost of ₹85 crore in Jaipur’s Central Park last year, during the Congress-led regime in Rajasthan. The museum has not been opened to the public, reportedly because of the administration’s engagements with the State Assembly and Lok Sabha elections.

Pakistan coach Gary Kirsten stated that “not so great decision making” contributed to his side’s defeat to India in the Group-A T20 World Cup clash here on Sunday. The batting unit came apart in the chase, after being well placed at 72 for two. With 48 runs needed from eight overs, Pakistan found a way to panic and lose. “Maybe not so great decision making,” Kirsten said at the post-match press conference, when asked to explain the loss.
