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,
