There was a time when the water was clean and the people used to use it for household purposes. In Mumbai, during the festival of Ganesh Chaturthi, the statue of the Lord Ganapati (Hindu Religion), was drowned in this river too. Nowadays, it is not done, since the river is dirty.
In 2006 during the major flood in Mumbai, Poisar river had flooded, and water had overflown the banks into a building compound, contaminating a Water Tank. Those living in the surroundings had undergone great distress following an outbreak of various waterborne diseases.
