On July 13, 2009, the environment department of state government framed new rules for conservation of state’s 20 notified rivers and gave a period of three years to all civic bodies to stop sewage from flowing into these rivers. Nagpur Municipal Corporation has done precisely nothing to implement these directives and the condition of Nag and Pili rivers in city has only worsened in this period.
The environment department framed the new policy for improving quality of water in notified rivers. The department classified the 20 rivers into four categories- A-I to A-IV. Nag river is one of the 20 and was classified as A-IV, the lowest among all categories probably due to it now almost entirely carrying city’s sewagfe.
Nag river basin is listed among state’s river basins that includes such major rivers as Krishna, Godavari, Tapi, and Wainganga etc. The name of Pili river is too mentioned in the list as a tributary of Nag river.
