Arkavathi river rejuvenation to proceed under expert panel and PPP model: BWSSB chairman

Bengaluru

In a significant move toward ecological restoration, the Bangalore Water Supply and Sewerage Board (BWSSB) has announced the formation of an expert committee and the adoption of a Public-Private Partnership (PPP) model to rejuvenate the Arkavathi River, once a key water source for Bengaluru.

BWSSB chairman Ram Prasath Manohar, addressing a stakeholders’ meeting on Tuesday at the Board’s central office, said, “The Arkavathi river rejuvenation process is underway. A comprehensive project report is being prepared in coordination with government departments, NGOs, and civic stakeholders.”

The Arkavathi River, originating from Nandi Hills, flows about 53 km through a basin of 1,400 sq km before merging into the TG Halli reservoir. The river once played a critical role in supplying water to the city. However, due to unchecked industrial growth, discharge of untreated effluents, and severe encroachments, the reservoir's water has turned unsafe for consumption.

“Earlier, water from the Arkavathi and its tributary Ettinahole would be blended and supplied to the city. Now, with the TG Halli reservoir contaminated, urgent measures are necessary,” said Manohar.

The Infrastructure Development Corporation (IDECK) has already conducted surveys across Hesaraghatta, Madanayakanahalli, and BBMP zones, and a detailed report is being finalized. Manohar noted, “Only 15% of the river’s stretch lies under BWSSB’s jurisdiction, which is why we are involving multiple stakeholders in planning.”

The expert panel will include members from:

• BBMP, BDA, KIADB, KSPCB, and DMA

• District administrations of Bengaluru Urban and Rural

• NGOs like Biome Trust, Paani Earth, and Art of Living

• Scientists from the Indian Institute of Science (IISc)
