Bengaluru Water Authority Plans to Build 17 New Sewage Treatment Plants

06 Jan 2025 CW Team

The Bangalore Water Supply and Sewerage Board (BWSSB) has announced plans to construct 17 new sewage treatment plants (STPs) with a total capacity of 583 million litres per day (MLD), aiming to enhance wastewater treatment and reuse across Bengaluru. This initiative is designed to address the city’s increasing wastewater burden and build a pipeline network to deliver treated water to industrial areas.

Currently, BWSSB operates an extensive network of 12,000 km of pipelines, supplying 2,250 MLD of water daily from the Cauvery River, located 100 km away. Around 85-90% of this water is returned as wastewater from households. The new STPs are expected to bridge the treatment gap, with the total wastewater generation in the city now exceeding 2,000 MLD.

BWSSB's existing 33 STPs treat about 1,200 MLD of wastewater, but another 800 MLD still requires treatment. To address this, BWSSB plans to invest ?2,200-2,400 crore in the new plants, according to utility chairman Ram Prasath Manohar.

Of the 1,200 MLD treated wastewater, 750 MLD is already being reused by institutions such as the Indian Air Force, ITC, BEL, Bengaluru International Airport, and various parks. Further plans are in place to extend the use of treated water to industrial areas through a dedicated pipeline network.

Additionally, BWSSB is working on the Koramangala-Challaghatta Valley project, which aims to release treated wastewater into 145 lakes in surrounding districts. Currently, 265 MLD is being pumped, with the remaining 135 MLD expected to be supplied once the new STPs are constructed.
