Chennai industries to now use treated sewage water – India CHENNAI: IN ten more days, Chennai will become the first Indian city to recycle sewage and supply it for industrial purposes. A new treatment plant is being built in Kodungaiyur, which is likely to be completed by the first week of August. This plant will supply recycled sewage water to industries, thereby ensuring that fresh drinking water is reserved for residential use. The move, Metro Water Board officials say, will help city tide over water crisis. (LINK). HIWI042019-08-01T15:49:15+02:00
