Bengaluru: The Bengaluru Water Supply and Sewerage Board (BWSSB) has issued notices to 499 apartment owners in Bengaluru for releasing the sewage water into the Underground drainage (UGD) that carries rain water.

The BWSSB has warned these apartment owners that if the problem is not fixed, then the drinking water supply to them will be cut. It has said that strict action will be taken against the defaulters.

It has been made mandatory that every apartment that has more than 20 houses must have Sewage Treatment Plants (STPs). While constructing an apartment, it is a must that the owner needs to apply for the same and pay monthly maintenance charge for it.

Currently, apartments in Ayyappanagar, Hoodi, Kodigehalli, Mahadevapura, KR Puram, Bhattarahalli, Rajarajeshwari Nagar, Marathahalli, Pattandur Agrahara, KaViKa Layout, Kengeri, Bhyrasandra, Malleshpalya, Kalidasa Layout and surrounding areas have been identified and notices have been served to them in this regard.

Meanwhile, the Karnataka State Pollution Control Board (KSPCB) is also contemplating on training people to treat the sewage treatment plants. Installing STPs will cost anywhere between Rs 1 lakh and Rs 5 lakh. But the apartments will not have drinking water provided by the BWSSB if they fail to fix the STP problem.

The action was taken after there were complaints of people connecting the sewage pipeline to the underground drain and releasing water without treating it.

The KSPCB is planning to train youths interested in treating the STPs under Pradhan Mantri Kaushal Vikas Yojana. Reports state that the secretary of the department of skill development has accepted this request.
