Volume of sewage that is discharged into the Nag and Pili rivers each day (i.e. 430 MLD). Incidentally the river lends its name to the city of Nagpur and both the rivers run through the city's municipal limits. Pollutants spill over into the Kanhan and Wainganga rivers as well as the Gosikhurd dam.

Estimated cost of the project revised in Jul 2019 as against Rs. 1,476.96 crore estimated in Jun 2014. Nagpur Municipal Corporation (NMC) will provide 15% of the funding while the central govt. will provide the remaining funds by taking a soft loan from Japan International Cooperation Agency (JICA).

Number of small sewage treatment plants (STPs) will come up on Nag river (3) and Pili river (2).

Combined treatment capacity of 3 Sewage Treatment Plants (STPs) that are proposed to be set up near the Nag river. 5 MLD - at Shankar Nagar, 40 MLD near Sangam at Yashwant stadium and 3 MLD at St Xavier’s School. A 5 MLD STP has already been constructed at Mokshadham.

Proposed treatment capacity of 2 small STPs to be constructed on Pili river. 37 MLD at Martin Nagar and 6 MLD at Wanjra . They will be constructed by Nagpur Improvement Trust (NIT) apart from the one almost nearing completion at Mankapur.

Number of polluting streams that empty into the 2 rivers. These would be intercepted or flow diverted to the Bhandewadi sewage treatment plant for treatment.

Settlements along the river that have been identified as major contributors to the pollution. Besides solid waste being dumped from these settlements, waste water from toilets in the slums and other layouts, stormwater drains and sewage are also discharged directly into the river without prior treatment. An estimated Rs. 5.8 crore will be spent on non-sewerage works, including community toilet blocks, riverfront development, electric crematoria and cattle washing centre.

Length of sewage lines that will be laid in all as part of the comprehensive sewerage system.

The project was first approved on this day, but the administration took a long time to come up with a plan. High Court took suo motu cognisance of media reports in 2010 and directed NMC to mitigate pollution.

NRCD rejects NMC's plan and asks for Indian Institute of Technology (IIT), Roorkee, to help NMC prepare the plan. Upon finalization, the cost of the project was fixed at Rs. 1,476.96 crore.

NRCD approves the project. Japan International Cooperation Agency (JICA) approached for a soft loan for the project from which share of centre and state will come to NMC.

Likely start of the project will be middle of the year after completion of appraisal of the project by JICA.

Target year set by NMC by when the river would be made pollution free.

Project yet to kick off, however, inordinate delays have meant that the cost of the project has by now gone up by 65%. The project will now cost Rs. 2,434 crore as against the earlier estimation of Rs. 1,476.96 crore. NMC submits escalated costs to National River Conservation Directorate (NRCD) for approval.

NRCD approves escalation costs after city MP and Union Minister for Road Transport and Highways Nitin Gadkari holds meeting with officials of Nagpur Municipal Corporation (NMC), NRCD, Ministry of Jal Shakti, and Japan International Cooperation Agency (JICA).

Official Development Assistance (ODA) loan of 29,082 million Japanese Yen that JICA will provide based on an agreement signed on 01 Apr 2020 between the agency and the Government of India. Dr. C.S. Mohapatra, Additional Secretary, Department of Economic Affairs, Ministry of Finance and Mr. Katsuo Matsumoto, Chief Representative, JICA India were the respective representatives.
