The Bangalore Water Supply and Sewerage Board (BWSSB) is launching a project to supply tertiary-treated water to the Peenya Industrial Area, Asia’s largest industrial hub. The project involves treating water from the Nagasandra Sewage Treatment Plant (STP) to make it “ultra pure” for industrial use. This includes establishing a tertiary treatment plant in a Public-Private Partnership, laying a 27 km pipeline, and constructing a sump-cum-pump house and overhead tank. The project aims to reduce the reliance on Cauvery water for industrial purposes, reserving it primarily for residential use.

Bengaluru to Pioneer “Ultra Pure” Water for Industries, Prioritizing Cauvery for Homes
Bengaluru, January 2, 2026 – The Bangalore Water Supply and Sewerage Board (BWSSB) announced today a groundbreaking initiative to supply tertiary-treated water to the Peenya Industrial Area, aiming to revolutionize water usage and conservation in the city. This ambitious project will provide 4 million liters per day (MLD) of “ultra pure” treated water from the Nagasandra Sewage Treatment Plant (STP) to industries, reducing their reliance on the Cauvery River, which will be reserved for residential use.
The BWSSB plans to establish a tertiary treatment plant at the Nagasandra STP, employing a Public-Private Partnership model. The Chairman of BWSSB, V. Ram Prasath Manohar, anticipates the plant to be operational within three to four months of securing a partner. This advanced treatment will ensure the water surpasses National Green Tribunal (NGT) standards, making it highly suitable for industrial applications.
To facilitate the supply, the BWSSB will invest an estimated ₹27 crore in infrastructure, including a 27 km distribution pipeline, a sump-cum-pump house, and a 5 lakh liter capacity overhead tank. This will create a dual piping system to prevent treated water from mixing with potable water sources, marking a first-of-its-kind project in Bengaluru.
“We are working with the motto ‘Cauvery for Homes, Ultra Pure Treated Water for Industries’,” said Manohar. “We are willing to partner with other industrial hubs as well to provide ultra pure treated water.” This initiative signals a major step towards sustainable water management and a commitment to prioritizing resources for the city’s growing population.
