Vrishabhavathi STP functions below capacity

By Madhuvanthi Srinivasan

Bangalore, Sep 14, 2017: Bangalore’s oldest and second largest sewage treatment plant (STP) is functioning below capacity.

The Vrishabhavathi Valley Treatment Plant that can treat 60 million litres per day (MLD) only processes 15 MLD. And, the state government is planning to set up another plant with a 150 MLD capacity in the area soon.

The Vrishabhavathi Valley Treatment Plant was set up in 2003 to provide treated water to a proposed 1400 MW gas power plant in Bidadi. However, the Bidadi gas plant project has been delayed since 2012 due to litigation issues. Mr. B. Sudarshan, Public information officer, Karnataka Power Corporation Limited (KPCL) said, “There are some issues. It started quite long back. Tenders were invited twice or thrice. The case is still in the court”.

Mr. Bharath Kumar, Assistant Executive Engineer, Bangalore Water Supply and Sewage Board (BWSSB) said, “The Vrishabhavathi Valley Treatment Plant supplies treated water to nearby construction zones, effluent treatment plants and to its own jetting machines. There are plans to expand pipelines from the treatment plant. We have awarded work in four packages. Work will start in three months.” Arvind Mills on Mysore Road reuses 3 MLD of water from the Vrishabhavathi STP.

Bangalore generates 1,440 MLD of sewage. The 18 functioning STPs have a current treatment capacity of 846 MLD. Dr. T.V.Ramachandra, Centre for Ecological Sciences, Indian Institute of Science, Bangalore said, “The concept of sewage treatment plants will work in Bangalore when there is no lacuna in the management. It has been working in Jakkur Lake since 2010”.
The Karnataka government has proposed to build another STP with a capacity of 150 MLD in the Vrishabhavathi Valley. This is along with three other STPs proposed in other major valleys of Bangalore at a budget of Rs. 1202 crores. “But, I wonder whether the current bureaucracy understands ‘optimal utilization’. They want to run units inefficiently just to maximise their benefits” said Dr. T.V.Ramachandra.
