About 6.2 billion litres of untreated industrial wastewater is generated every day across India, said Mr Suman Bery, Vice Chairman, NITI Aayog, at the valedictory session of the 13th IWA International Conference on Water Reclamation and Reuse, hosted by FICCI. MrBery underlined the massive potential of the water and wastewater sector, with the market growing at about 15 to 20 per cent annually. He noted that urban wastewater management could be a crucial component in the circularity of water use.

"So far, there are no firm Indian standards stipulated for the use of treated water for various purposes, including irrigation. Perhaps we can use guidelines published by the ISO to use treated water for irrigation purposes", he said. In his special keynote, Thiru Shiv Das Meena, Additional Chief Secretary, Municipal Administration and Water Supply Department, Government of Tamil Nadu, underscored the need to classify the treated used water based on the usage and then fix the quality parameters for that water.Ms D Thara (I.A.S.), Additional Secretary (A&CV), Union Ministry of Housing and Urban Affairs, Dr Thomas Michael MOLLENKOPF, President, IWA, Dr Joseph Lahnsteiner, Chair, IWA Reuse Specialist Group, and Dr GSK Velu, Chairman, FICCI Tamil Nadu State Council, also spoke on occasion.
