The Bangalore (BWWSB) Council (BWWSSB) works to add 470 billion capacity to treat waste water in 26 new wastewater treatment plants (STP) by the end of 2025.
This would mean adding approximately 35% of waste water purity to the existing capacity of 1,348.5 billion in 34 STP and shifted the capacity of the city to 1,818.5 billion. The largest of all comes to Vrishabhavathi Valley, Mysuro Road, with a capacity of 150 billion, followed by STP in Hebal and Horamava with a capacity of 60 billion. It is important that 14 of these new STPs with a combined capacity of 124 billion come in 110 villages that acquire new water connections and underground drains (UGD).
“We are working to complete these ongoing projects until December 2025. Many of the STP in 110 villages will also be completed much earlier,” said V. RAM Pig Manohar, chairman of BWWSSB. “As soon as these STPs are entrusted, our ability to treat waste water will increase significantly. We also invest in tertiary processing of this water to ensure its use in the city for not writing and filling lakes. We will save a lot of water in this way,” he added.
However, there is no sufficient demand for treated water from the existing STP itself. Sources said the demand for treated water dropped compared to the summer of 2024, when there was a severe water crisis.
The gap in therapeutic capacity still remains
The city currently has an infrastructure to develop up to 2,220 waters from the Cauvera River, from which approximately 1,800 billion is drawn. This is expected to increase because more new connections are listed under the Cauver V phase. In addition, the use of Groundwateris, which is difficult to quantify, which means that only with these 26 new STPs (adding total treatment capacity of 1,818.5 billion) will still be a large gap in the capacity of the city.
The survey, which was ranked by the Board of Directors after 1,538 km long UGD and 14 STP building at the price of the CRORE 925 GBP in 110 villages, shows that these areas still need more than 400 km of UGD lines and another 9 STP, estimated at around 850 Crore. The Board of Directors expects these works to be interested in the Water Security and Resilience program, according to which the international agency provides a loan of 3,500 GBP Crore, and is expected to receive over 1,000 GBP Crore.
