Bangalore Water ​Supply and ​Sewage Report

With the polluted lakes no longer supplying it its water, the Bengaluru draws 1350 MLD from the Cauvery river, the lifeline of the city and other districts, for its needs and lets out almost 80 per cent of it as sewage later.

Although it generates 1,000 MLD of sewage on an average on any given day, sadly it's not able to treat all of it.

The Bangalore Water Supply and Sewerage Board ( BWSSB) admits it treats only 843 MLD at its 14 Sewage Treatment Plants (STPs) across the city. In fact, until recently it only treated 721 MLD before it increased its capacity earlier this year.

How much water is supplied to Bengaluru every day?

 As many as 324 of 657 apartments  around Bellandur Lake do not have Sewage Treatment Plants

 Forty four  apartments are building STPs

The KPSCB has issued 170 notices  to the apartments around Bellandur Lake for failure to treat their sewage

Upcoming STPs across Bengaluru

But going by sources even this claim is not true. With power issues and lack of maintenance dogging its STPs, the BWSSB barely manages to treat 500 MLD,  they say.

Ask the BWSSB about its failure to treat all of the city's sewage and a senior officer admits that with its area of operation increasing over the years it is not able to fully do its job. "The water board was only tasked with taking care of water supply and the sewage in the core areas spread over 245 sq. kms when first set up.

But with the addition of areas under the city and town municipal councils, its jurisdiction increased by 330 sq.kms. Also with the addition of 110 villages it is now required to take care of another 225 sq. kms, which has made its job almost unmanageable," he contends.

  1. Bangalore is not unlike any other developing city, new development is going ahead without the necessary infrastructure in place.  People get the nice new apartments and a growing economy but to the detriment of the surrounding environment.  This conflict cannot continue as it will reach a turning point where if the local environment is so polluted (and lets face it the lakes are toxic dumps), that living there will be a the challenge in itself.  Either the City starts implementing better treatment and subsequent support infrastructure, or the people living there implement their own solution.  No matter what everyone will still have to pay more.

    Keeping the environment clean or even cleaner than it currently is costs money, but what that does generate is opportunity.  Where there are opportunities there is potential for more economic development.  Keeping the city clean of sewage pollution is the opportunity providing more wealth and employment.  With the two working hand in hand this will lead to sustainable development, something sadly lacking here.

    What will it take for all sides to reach agreement?  There needs to be momentum to reach this point.  Somebody or organisation needs to throw in an olive branch as this cannot continue as it stands. 

  2.  STPs are technically unable to treat sewage as they cant remove nutrients or heavy metals. Most of them are dogged by maintenance. The By pass valves at pumping stations that are pumping untreated sewage to the STPs help them a lot, they just divert the untreated sewage into the public water rivers, streams, drains or lakes.  The first step would be for the public to ask for locking up the  By -pass valves. Then the STPs will become worse than the drains and the workers may just run away due to toxic levels of H2S gas.
