Bangalore to Quench the Non-potable Water Needs of Residential Homes with Treated Lake Water

The Bengaluru Water Supply and Sewerage Board (BWSSB) is looking into new methods to deal with the water crisis that city is currently facing.

Water Treatment Plant (WTP) is the next step after consolidating Sewage Treatment Plants (STP). BWSSB is planning to construct a WTP as their pilot project of employing treated lake water for certain purposes near the Yele Mallappa Chetty lake on Old Madras Road. With Krishna Raja Puram as their focus, they plan to direct the treated lake water to residential homes for non-potable use.

Capable of treating 15 million litres per day, the STP at the Yele Mallappa Chetty lake receives a low volume of sewage refuse which ensures proper and complete treatment of the water. The new WTP is supposed to be built downstream.

Long Term Planning is the need of the hour

BWSSB believes that this project will have takers for at least non-potable use. Also, this happens to fit into BWSSB 2050 Vision document for long-term plans with respect to the water crisis. Currently, the Karnataka Government is supplying treated water for irrigation to Kolar, Anekal and Chikballapura. There were some issues that did surface which claimed that the treated water at Kolar had turned black and also instances of foaming was brought up.

Nevertheless, the government went ahead with the project. New Delhi and Chennai also seem to have gotten similar plans to battle the water problem.

Veena Srinivasan from the Ashoka Trust for Research in Ecology and Environment (ATREE) cautioned that if we let the treated water be, it will overflow and could cause a deluge where incoming rainwater does not help our case.

All the more reasons to set up a Water Treatment Plant and direct it to homes for non-potable use!

When such steps are taken, we, as responsible citizens, need to understand the gravity of the matter and offer our encouragement and participation.
