Living in North and East Bengaluru? Here are the 448 BWSSB 'High-Stress' Pockets you need to know

As Bengaluru enters a hotter-than-usual February, BWSSB has rolled out a Rs 10.1-crore summer preparedness plan and flagged 448 high-alert water-stressed pockets, aiming to avoid shortages through advance mapping, decentralised storage and faster tanker support across the city.

IMD expects Bengaluru’s day temperatures to stay near 29°-30° Celsius, with the city already touching 30° and areas around Kempegowda International Airport likely to get even warmer, raising concern over groundwater behaviour between March and May, especially in north and east Bengaluru, where many residents still rely on borewells.

Bengaluru water summer plan and high-alert pockets

BWSSB officials said the 448 high-alert locations are not full neighbourhoods but compact micro-pockets inside larger supply zones, mostly interior stretches that could face sharp stress if borewells fail, so this year the Board has moved away from complaint-driven emergency responses and instead mapped vulnerable clusters in advance where drinking water could become critical.

To support these pockets, BWSSB plans decentralised storage by placing 1,260 mini-water tanks across its four zones, each 5,000-litre Sintex tank acting as a local buffer for drinking water in stress-prone streets, while the overall strategy also focuses on quicker tanker turnaround so refills reach these clusters without long gaps.

Bengaluru water tankers and distribution network

On the transport side, 117 BWSSB tankers have been earmarked and 104 private tankers shortlisted as backup, with about 60 more tankers arranged in reserve as demand rises; each standard BWSSB tanker carries between 6,000 and 12,000 litres, and 91 additional Cauvery water filling points are planned along with filling support for 196 reverse osmosis plants across Bengaluru to strengthen last-mile distribution.

BWSSB is also pushing infrastructure upgrades, with 47 water supply works and 14 lake-filling projects currently under way to boost local availability during the peak months, while the Board says these efforts, combined with the decentralised storage and tanker network, should reduce pressure on fragile borewells in outer areas.

Bengaluru water Cauvery supply and village coverage

The early planning comes as February temperatures stay above normal and groundwater prospects remain uncertain, yet BWSSB chairman Ram Prasath Manohar V said the city’s position is stronger than in 2024, stating, "I don't see much summer difficulty for the city; we are well prepared this year," while pointing to higher Cauvery supply capacity.

Under the Cauvery Stage V augmentation, BWSSB’s total pumping capacity now stands at 773 million litres per day, of which about 400 MLD is currently drawn, and Manohar said, "We still have more than 40% additional pumping capacity available. Even in a worst-case scenario where groundwater levels fall more than expected, we can match the requirement with Cauvery water," outlining how river supply can cover a shortfall.

One major issue last year was that several newly added villages inside BWSSB’s expanded limits were not fully commissioned, but Manohar said most of those areas are now linked to the formal network, with only four villages in the east and four in the north still pending because of land disputes, adding, "Except those, all are fully commissioned," which, according to officials, reduces heavy dependence on borewells in the outer belt, while senior staff including chief engineers, assistant executive engineers and water inspectors have been instructed to carry out daily field visits to track supply conditions on the ground.

Bengaluru water usage rules and last year’s experience

Manohar has also cautioned residents against using Cauvery drinking water for non-essential activities such as washing cars, warning that such misuse will attract penalties, and officials said enforcement teams will tighten checks during summer to protect treated drinking water for essential household needs, especially in the mapped high-alert pockets.

Last year, several parts of east and north Bengaluru saw borewells dry up, queues for private tankers grow and tanker prices rise sharply, and BWSSB now hopes that advance identification of micro-pockets, additional Cauvery capacity, new filling points, village commissioning and expanded tanker logistics will help the city avoid a repeat as the peak summer period approaches over the next two months.
