Treated water may quench parched parks in City

The Bangalore Water Supply and Sewerage Board (BWSSB) has proposed to the BBMP to use secondary and tertiary treated water for gardening and maintenance of parks in the City.

The BWSSB has also written to government departments like the Horticulture department, Bangalore Development Authority (BDA), Bangalore Metro Rail Corporation Limited (BMRCL) and big builders.

According to the Bruhat Bengaluru Mahanagra Palike (BBMP) website, there are 1,288 parks within its limits, spread across eight zones. 

A senior BWSSB official said none of the BBMP parks is utilising treated water and depends on borewells. 

“We have set up a waste-water treatment plant of one MLD capacity at Kempambudhi Lake Park in Hanumanthnagar. But the treated water is not being used for gardening,” the official said.

Rudregowda, BWSSB marketing officer (Treated waste water), said treated water is being used only at Cubbon Park and Lalbagh Botanical Garden. 

He said: “We sell secondary treated waste water at Rs 10 per 1,000 litres to organisations with their own transportation and tertiary treated water at Rs 15 per 1,000 litres. If the Palike arranges its own transportaion, we can easily supply water.”

While the secondary treated water is available at secondary waste water treatment plants at Vrishabhavathi Valley, Mylasandra, Nagasandra, Hebbal, Jakkur, Krishnarajapuram, Kadubeesanahalli and K&C Valley; tertiary treated water is available at tertiary plants located at Vrishabhavathi Valley, Yelahanka, Cubbon Park, Lalbagh and Kempambudhi Lake.

Cost-effective“The municipal corporation will be spending less if it switches to treated water. As the waste water goes through various stages of treatment, it is odourless and is fit for gardening, washing and cleaning. We are willing to sell treated water to even apartments provided the treatment plants are close by,” added Rudregowda.

Treated water is also being supplied to Kempegowda International Airport, Bharat Electronics Limited (BEL) and Rail Wheel Factory at Yelahanka among others. 

While BBMP Commissioner G Kumar Naik was unavailable for comment, Mayor B N Manjunatha Reddy admitted that borewells are a costly affair. 

The mayor added that he will look into treated-water after discussions with higher officials.
