The Bangalore Water Supply and Sewerage Board (BWSSB) has floated tenders for a project to provide tertiary treated water to the Peenya Industrial Area, said to be Asia’s largest.
BWSSB will provide 4 million liters per day (MLD) of treated water from Nagasandra Sewage Treatment Plant (STP) to the industrial area. While the effluent from the WWTP meets National Green Tribunal (NGT) standards, the BWSSB is set to set up another tertiary treatment plant to further treat the effluent from the WWTP before it is supplied to industries.
BWSSB chairman V. Ram Prasath Manohar said this would make it “ultra clean” and increase acceptability among users as well as its durability.
The Board has recently piloted a 70 KLD capacity tertiary treatment plant at Kadubeesanahalli STP and is deploying the same technology at Nagasandra STP. “The tertiary treatment plant will be run on Public Private Partnership mode for which we are looking for an ideal partner. Once we get that, it can be commissioned in three to four months,” Manohar said.
Meanwhile, BWSSB will spend an estimated ₹27 crore to lay a 27 km distribution pipeline between Nagasandra STP and industries in Peenya Industrial Area and construct a transfer pump house and 5,000 liter overhead tank. This will introduce a dual pipeline system to ensure that treated water is used for non-potable purposes and not mixed with potable water, a first-of-its-kind project in Bengaluru.
“We are working with the motto ‘Cauvery for households, ultra-pure treated water for industry’. We are willing to collaborate with other industrial centers to provide ultra-pure treated water,” said Mr. Manohar.
