The Bangalore Water Supply and Sewerage Board (BWSSB) has imposed strict restrictions on the use of drinking water across Bengaluru after declining groundwater levels and a weak southwest monsoon raised concerns over the city’s water security.
Invoking Sections 33 and 34 of the Bangalore Water Supply and Sewerage Act, 1964, the Board has banned the use of potable water for filling swimming pools, washing vehicles, construction work, road cleaning, decorative fountains, and several other non-essential activities.
Swimming pools used for training athletes preparing for state and national-level competitions are exempt, subject to prior approval.
BWSSB has also made it mandatory for apartments, hotels, restaurants, commercial establishments, government buildings and public places to install flow restrictors or aerators by 31 July to reduce water consumption.
Explaining the move, BWSSB Chairperson Manjula N said the restrictions were necessitated by poor rainfall and falling reservoir levels, with combined storage at just 203 TMC out of 895.6 TMC, or about 23 per cent of capacity, compared with the same period last year.
An India Meteorological Department (IMD) official also pointed to an estimated 40 per cent rainfall deficit, attributed largely to El Niño conditions, warning that the chances of significant improvement later in the monsoon remain low.
While many residents have welcomed the preventive measures in light of last year’s severe water crisis, others have called for stronger long-term investments in rainwater harvesting, lake restoration and urban planning alongside conservation efforts.
Preventive Curbs to Save Every Drop
The latest directives represent one of Bengaluru’s most comprehensive attempts yet to reduce unnecessary consumption of treated drinking water before supplies become critically strained.
Besides prohibiting potable water for recreational and non-essential uses, BWSSB has instructed residential complexes, shopping malls, hotels, restaurants, government offices, religious institutions and other public establishments to install aerators or flow restrictors on taps and water outlets used for cleaning.
These simple devices can reduce water consumption by an estimated 30 to 50 per cent without significantly affecting water pressure, making them an effective conservation measure in a city where every litre counts. Officials have also advised that treated wastewater or other non-potable sources should be used wherever possible for activities such as construction and cleaning.
Highlighting the urgency, BWSSB Chairperson Manjula N said the restrictions were introduced because rainfall has remained well below expectations and reservoir storage has fallen sharply.
The Cauvery basin, Bengaluru’s principal drinking water source, currently holds only 36 TMC against its capacity of 114.5 TMC, while the city’s overall reservoir storage remains substantially below last year’s levels.
BWSSB estimates that Bengaluru’s effective population, including permanent and floating residents, is now close to 1.4 crore, making equitable distribution and responsible use of drinking water essential.
Authorities have warned that violations could attract a ₹5,000 fine, additional daily penalties for continued non-compliance, possible reduction in water supply and further action under the BWSSB Act, signalling that enforcement will accompany public awareness efforts.
Lessons from a City Living on Borrowed Water
The restrictions come barely a year after Bengaluru witnessed one of its most severe water shortages, when thousands of borewells ran dry, tanker prices surged dramatically and many neighbourhoods struggled to access reliable drinking water.
The crisis exposed the city’s growing dependence on groundwater as urban expansion continues to outpace water infrastructure. Although Cauvery water remains Bengaluru’s primary source of drinking water, large sections of the city including apartment complexes, industries and peripheral layouts—continue to rely heavily on groundwater extracted through borewells.
Reduced rainfall has only intensified this dependence, causing groundwater tables in several areas to decline further. Earlier studies by researchers and water experts had already warned that many wards in northern and western Bengaluru were witnessing alarming groundwater depletion, prompting BWSSB to strengthen monitoring and prepare contingency measures.
Experts increasingly argue that Bengaluru’s water challenges are no longer seasonal but structural, driven by rapid urbanisation, shrinking lakes and wetlands, paved surfaces that prevent groundwater recharge, and sustained over-extraction of aquifers.
Meteorological officials have added to these concerns by reporting a 40 per cent rainfall deficit this monsoon, attributing it largely to El Niño conditions while indicating that the prospects for a substantial recovery in rainfall remain limited.
The latest measures therefore represent not merely an emergency response but an attempt to prevent another full-blown urban water crisis through early intervention rather than reactive restrictions after supplies begin to fail.
The Logical Indian’s Perspective
Bengaluru’s latest water conservation measures underline an uncomfortable reality confronting many rapidly growing Indian cities: water security cannot depend solely on good monsoons or emergency restrictions. Conserving drinking water during periods of scarcity is both necessary and responsible, particularly when millions of people depend on shared public resources.
At the same time, lasting solutions require governments, institutions, businesses and citizens to work together on restoring lakes, protecting wetlands, strengthening rainwater harvesting, expanding wastewater recycling and planning urban growth with ecological sustainability at its core. Public participation will be just as important as regulatory enforcement, because every household and establishment has a role in reducing unnecessary consumption.
