Residents of Bengaluru are advised to prepare for a major Cauvery water supply disruption lasting up to 24 hours, starting early February 5, as the Bengaluru Water Supply and Sewerage Board (BWSSB) undertakes essential pipeline work on the city's main drinking water system.

The temporary shutdown will affect large parts of south and central Bengaluru, where households and commercial establishments depend heavily on Cauvery water. Officials have cautioned that several areas may receive no water at all or only minimal pressure during the shutdown period and have urged residents to make advance arrangements.

Bengaluru Water Cut On February 5 6 Cauvery Supply to Be Shut for 24 Hours In South and Central Areaa

Residents of Bengaluru are advised to prepare for a major water supply disruption lasting up to 24 hours, starting February 5, as the Bengaluru Water Supply and Sewerage Board (BWSSB) undertakes essential maintenance work on the Cauvery Water Supply System.

The temporary shutdown will affect large parts of south and central Bengaluru, where households and commercial establishments depend heavily on Cauvery water. BWSSB officials have cautioned that several areas may receive no water or very low pressure during this period and have urged residents to make advance arrangements.

Bengaluru Water Supply Cut for 24 Hours; Check Date and Time Area-wise

According to BWSSB, pumping stations under Stage I and Stage II of the Cauvery Water Supply Project will remain shut from 6 am on Thursday, February 5, to 6 am on Friday, February 6.

During this 24-hour window, Cauvery water supply will either be fully stopped or severely restricted across multiple neighbourhoods in south and central Bengaluru. Restoration will begin gradually once pumping operations resume after the completion of maintenance work.

Why Cauvery Water Supply Is Being Stopped In Bengaluru?

BWSSB chairperson V. Ram Prasath Manohar said the shutdown is required to carry out critical pipeline-linking work involving 1,200 mm and 700 mm diameter pipelines.

Officials explained that this work cannot be safely executed while the Cauvery system is operating at normal pressure. Temporarily halting pumping is therefore essential to ensure worker safety and to complete the project without risking damage to the network. The linking work is part of broader efforts to strengthen Bengaluru's water distribution system and improve long-term supply reliability.

BWSSB officials said the February shutdown is part of a planned infrastructure upgrade aimed at strengthening Bengaluru's Cauvery water supply network. Such temporary disruptions, they noted, are unavoidable during large-scale pipeline works but are necessary to ensure smoother and more reliable water distribution in the long run.

The board reiterated that the work has been scheduled with advance notice to minimise inconvenience and urged residents to plan accordingly.
