# Bengaluru Treated Water Use Surges 80% But Trails Summer Peak Despite New Mandates

Monthly sales of treated water in Bengaluru reached 57.32 lakh litres in July following a ban on potable water for non-essential tasks. Despite this growth, volumes remain significantly below April levels, suggesting uneven compliance across the city's construction and residential sectors.

## Key takeaways

- Bengaluru saw an 80% month-on-month increase in treated water sales in July after a potable water ban.
- Enforcement fines reached 30 lakh rupees in July, significantly exceeding the revenue from water sales.
- Large construction firms are adopting treated water, while small projects still rely on borewells.
- Apartment residents are resisting the use of recycled water for swimming pools, leading to pool closures.

## Slow Transition to Recycled Water

Data from the Bangalore Water Supply and Sewerage Board (BWSSB) reveals a significant rise in treated water consumption following a July 5 mandate. Usage climbed from 31.68 lakh litres in June to 57.32 lakh litres in July, an 80% increase. This shift follows strict regulations prohibiting the use of potable water for non-drinking purposes due to a monsoon deficiency caused by the El Niño effect.

However, current consumption remains 42% lower than the 1.05 crore litres recorded in April. This gap suggests that the city has not yet matched the water conservation levels seen during the peak of summer, even as the BWSSB ramps up enforcement. The board collected approximately ₹30 lakh in fines during July, a figure that dwarfed the ₹2.23 lakh in revenue generated from actual treated water sales.

## Construction and Residential Challenges

The construction industry remains a primary consumer of treated water, but adoption is inconsistent. Large-scale developers have largely integrated recycled water, with some installing additional on-site treatment facilities to improve quality. In contrast, smaller projects continue to rely on private borewells. Industry leaders from CREDAI-Karnataka have called for the inclusion of treated water standards in the National Building Code of India to formalize these practices.

Residential communities face different hurdles, particularly regarding swimming pools. Under current rules, only pools for competitive athletes can use potable water. The Bangalore Apartments’ Federation (BAF) noted that many residents are reluctant to use treated water for swimming, leading some complexes to let their pools dry out rather than refill them. BAF has also requested a waiver on the 25% water bill surcharge for apartments that stop filling their pools.

## Why It Matters

The disparity between fines collected and water sold indicates that illegal use of potable water remains a significant issue. As groundwater levels face pressure from poor monsoons, the success of the BWSSB's treated water initiative is essential for Bengaluru's long-term water security. The board is currently attempting to map apartment-based Sewage Treatment Plants (STPs) to nearby industrial and construction users to facilitate a more efficient distribution network.

## Key Facts

- BWSSB sold 57.32 lakh litres of treated water in July at a rate of ₹10 per kilolitre.
- April recorded the highest volume of treated water sales this year at 1.05 crore litres.
- Authorities booked nearly 800 violations in July, resulting in ₹30 lakh in penalties.
- Treated water revenue for July totaled ₹2.23 lakh, up from ₹1 lakh in June.
- The July 5 mandate was triggered by El Niño-related water scarcity.

## What Happens Next

The BWSSB is developing an action plan to link surplus treated water from apartment STPs directly to construction sites and industrial hubs. While a pipeline proposal for this exchange was previously suggested, the board is now focusing on mapping proximate users to finalize the logistics of this distribution system. Meanwhile, enforcement against potable water misuse for gardening and construction is expected to continue.
