The Mula-Mutha is a river in India, formed by the confluence of the Mula and Mutha rivers in the city of Pune, which later meets the Bhima River. The river flows through the village of Kavadi in the Solapur district, which witnesses a lot of migratory birds.
However, increase in pollution in the recent years has resulted in a reduction in the number of birds. Pollution from effluents released into the river at Pune has been found to cause high levels of pollution in the Bhima River and the reservoir of Ujani dam, resulting in a lot of water borne ailments.
Due to high levels of pollution, including 125 MLD of untreated sewerage water being discharged into the river by the Pune Municipal Corporation, the Maharashtra Pollution Control Board has classified the water quality to be of Class-IV. The Pune Municipal Corporation announced plans to clean up and restore the river by pumping in oxygen on the lines of restoration efforts undertaken in Mumbai for the Mithi River.
