BWSSB’s nano filtration makes treated water almost safe for drinking!

In a first-of-its-kind move, BWSSB has introduced nano filtration for treated water in Bengaluru, making it pure enough for industrial, domestic, and gardening use.

Bengaluru’s Silicon City residents struggling with water shortages may soon have relief. The Bangalore Water Supply and Sewerage Board (BWSSB) has unveiled a major innovation,  nano filtration of treated water, making it significantly purer and suitable for a wide range of uses.

The project has already received validation from the Indian Institute of Science (IISc), adding credibility to BWSSB’s efforts. A pilot project in select parts of the city has been successful, showcasing how treated water, after nano filtration, can meet quality standards for multiple applications.

Multiple uses, but not yet for drinking

Though the technology makes treated water pure enough to be considered safe even for drinking, BWSSB is currently planning to supply it for other purposes due to public hesitation about consuming water sourced from sewage treatment plants (STPs).

Where it can be used

The nano-filtered treated water will soon be available for:
•    Gardening and landscaping
•    Industrial operations
•    Household cleaning
•    Dishwashing
•    Vehicle cleaning
•    Large-scale enterprises and factories

Deputy Chief Minister is expected to officially announce the initiative in the coming days, explaining its benefits and raising public awareness about the economic and environmental advantages.

Officials say the move will help ease Bengaluru’s water scarcity, reduce reliance on Cauvery water, and promote sustainable water management. For now, BWSSB is focusing on non-drinking uses, but this marks a huge step forward in the city’s fight against water shortage.
