Mutha River

 
The Mutha River is a river in western Maharashtra, India. It arises in the Western Ghats and flows eastward until it merges with the Mula River in the city of Pune. It has been dammed twice, first at the Panshet Dam (on the Ambi River), used as a source of drinking water for Pune city and irrigation. The water released here is dammed again at Khadakwasla and is an important source of drinking water for Pune. One more dam has been built later on the Mutha river at Temghar.
After merging with the Mula River in Pune, it flows on as the Mula-Mutha River to join the Bhima River.
In 2014, the Government of Maharashtra announced that the Pune Municipal Corporation would build new Sewage treatment plants to ensure that no sewage would be dumped into the river.

The National Green Tribunal of India has the power to hear all cases relating to issues of the river under the Water (Prevention and Control of Pollution) Act, 1974 and the Water (Prevention and Control of Pollution) Cess Act, 1977. 
Considering the serious nature of encroachments on the Mutha river, the NGT in its latest order on 23 July 2019 ordered a committee to be formed to look into these issues.
