As much as of waste wa­ter is gen­er­ated by Class I and Class II towns in In­dia and this is ex­pected to grow three to five times to Of this 38,000 mld of sewage, 28,000 can be reused by in­dus­try – at least 8,000 mld by ther­mal power sta­tions and 20,000 mld by other in­dus­tries Arun Lakhani, chair­man and man­ag­ing di­rec­tor, Vish­varaj In­fras­truc­ture Ltd, which ex­e­cuted the Nag­pur Orange City Wa­ter Project.

The aim of the project was to ad­dress prob­lems of wa­ter that was be­ing wasted and not get­ting billed. The city was sup­ply­ing 575 mil­lion litres per day (mld) of treated wa­ter of which only 175 mld was get­ting billed and paid for. Most me­ters were ei­ther non-ex­is­tent or non func­tional. Also, the city was re­ceiv­ing wa­ter sup­ply for eight to 10 hours or on al­ter­nate days. The tanker mafia added to the prob­lem. On the sewage side, the city was gen­er­at­ing 550 mld of sewage and had the ca­pac­ity to treat only 100 mld. The re­main­ing un­treated sewage was pol­lut­ing wa­ter bod­ies that sup­plied wa­ter to the city.

For this project, the pri­vate com­pany in­vested 30% of the es­ti­mated project cost, 70% grants came from the JNNURM scheme, shared by both the state and the Cen­tral gov­ern­ment. The project was ini­ti­ated by the Nag­pur Mu­nic­i­pal Cor­po­ra­tion. This project was show­cased as the model case study for other cities at the launch of Atal Mis­sion for Re­ju­ve­na­tion and Ur­ban Trans­for­ma­tion (AMRUT) and Smart City ini­tia­tive.

The com­pany also un­der­took a waste wa­ter re­use project for Nag­pur city un­der which N at i o n a l T h e r m a l Powe r Cor­po­ra­tion ( NTPC) will be reusing 200 mld of treated wa­ter f rom the STP for its Mauda plant. By do­ing so, the city will get an ad­di­tional 200 mil­lion litres per day of wa­ter,
