Sewage treatment plants to come up  in four City lakes

The Bangalore Water Supply and Sewerage Board will set up sewage treatment plants in four lakes in the City, under the Atal Mission for Rejuvenation and Urban Transformation (AMRUT) scheme. The move would help in releasing treated water into the lakes.

The four lakes are located in Sarakki, Chikka Begur, Hulimavu and Agara, where the BWSSB proposes to set up the STPs to treat at least 5.5 MLD (millions of litres per day) of sewage water.

A BWSSB official said dirty water accumulated in the four lakes were connected to Bellandur lake. The frothy Sarakki lake indicates high contamination of water. By setting up the STPs, the board plans to reduce the amount of dirty water entering the 800-acre Bellandur lake, he said.

The Lake Development Authority, in response to the water board’s letter, has agreed to provide three acres of land in Sarakki, five acres each in Begur and Hulimavu, and eight acres in Agara to set up STPs, the official said.

Of the Rs 173 crore alloted under the AMRUT scheme, Rs 165 crore will be used for the construction of STPs and the rest for water supply, he said.

He said the board was expecting a letter from the Urban Development Ministry confirming the amount granted for the STPs. On obtaining the letter, a detailed project report will be prepared and, subsequently, construction of the STPs will be taken up in a month or two, he said.

About 1,300 MLD of sewage water is generated in Bengaluru. But the board is able to treat only 720 MLD of water through 14 STPs and work is in progress to construct STPs with a capacity of 369 MLD at different places.
