- BWSSB announced 60-hour water supply disruption in Bengaluru.
- Maintenance work on Cauvery Water Supply System from Sept 15-17.

Bengaluru Water Cut: The Bangalore Water Supply and Sewerage Board (BWSSB) has announced a major disruption to water supply in Bengaluru for up to 60 hours, beginning September 15 and continuing until September 17. The interruption is due to essential maintenance work on the Cauvery Water Supply System.
Residents in areas dependent on Cauvery water have been advised to store adequate water in advance and use it sparingly during the maintenance period. The shutdown is expected to affect large parts of the city, although the impact may vary across localities depending on their water source and available storage capacity.
The BWSSB has temporarily shut down operations at the Cauvery Stage V pumping station to carry out critical maintenance work. Additional maintenance is being conducted at Phase 1 and Phase 2 pumping stations under Cauvery Stages I, II, III and IV. These works are scheduled to continue until 6 am on Thursday, September 17.
The maintenance programme includes pipeline upgrades, electrical and mechanical inspections, and other measures aimed at improving the efficiency and reliability of the city's water supply infrastructure. Work is also being carried out at water treatment plants and key pipeline junctions across the main supply network.
Which areas of Bengaluru will be affected?
The disruption will primarily affect areas supplied through the Cauvery Water Supply Project, covering networks under Cauvery Stages I, II, III, IV and V.
Affected areas: Large parts of Bengaluru that depend on the Cauvery water supply network.
The duration and severity of the disruption may differ from one locality to another based on local storage facilities and the availability of alternative water sources.
Bengaluru's water supply system
Bengaluru's drinking water is sourced from the Cauvery river system, with the water travelling around 90 km to reach the city. The source is also approximately 350 metres below Bengaluru's elevation, requiring substantial energy to pump the water uphill.
The pumping process costs nearly Rs 3 crore in electricity every day, while the Cauvery system meets only about 50 per cent of the city's overall water demand.
