The growth of hyacinth has turned out to be a major health hazard for those staying along the Pavana, Indrayani and Mula rivers because of the mosquito menace. PCMC is likely to delay the work of removing water hyacinth from three rivers in Pimpri Chinchwad. Several areas along the Pavana river are densely populated. Increasing water hyacinth not only affects the environment but also human well – being. Sangvi is surrounded by rivers on three sides and there is rampant growth of water hyacinth in the rivers. Residents of Pimpale Gurav, located along the Pavana river also complained about the mosquito menace. The civic administration must start the work of water hyacinth removal to reduce the mosquito menace.
