Bengaluru Water Crisis: Can 130-year-old Hesaraghatta lake save the city from running dry?

The Bangalore Water Supply and Sewerage Board (BWSSB) is looking into tapping water from Hesaraghatta lake, situated on the outskirts of Bengaluru, to address the city's water shortage. This historic lake, created nearly 130 years ago, was initially built in 1894 by the former Mysore state to fulfil Bengaluru's drinking water needs. Now a popular tourist destination, the lake holds significant potential as a water source amidst the current water scarcity situation in the city.

Plans are underway to kickstart the project in May to meet the rising demand for water.

Ramprasath Manohar V, Chairman of BWSSB, conducted an inspection of Hesaraghatta lake and reported that it currently holds 0.3 tmcft of water, with healthy groundwater levels in the vicinity. The chairman expressed confidence in the adequacy of this resource, stating that 10 MLD (Million Litres per Day) of water can be pumped from the lake. He highlighted the presence of a BWSSB pumping station at Hesaraghatta, which could facilitate the water supply to areas connected to the station.


Meanwhile, water shortages in other regions will be addressed through the deployment of water tankers. Chairman Manohar emphasised that water from Hesaraghatta lake will only be sourced if the shortage persists in May.

“Our aim is to make sure that there is no shortage of water in Bengaluru, even in May,” he said as reported by Deccan Herald.

He underscored the board's commitment to ensuring an uninterrupted water supply in Bengaluru, even during the peak summer months.

The rejuvenation of Hesaraghatta lake has become imperative due to continuous encroachment on its catchment areas and the subsequent reduction in water storage capacity. Chairman Manohar launched the 'Triple R' campaign, aimed at reclaiming, reviving, and rejuvenating the lake. This initiative seeks to address encroachments in the Arkavathi and Vrishabhavathi valleys and enhance water management efforts.

With a focus on revitalising the Arkavathi and Vrishabhavathi rivers, BWSSB authorities aim to replenish groundwater levels through rainwater harvesting and revive 185 lakes across the city. The 'Triple R' project aligns with the city's goal of achieving water surplus status by July 2026.
