Hussain Sagar, the picturesque lake in the heart of Hyderabad was built during 1562 by Hazarath Hussain Sha Wali of the Qutub Shahi dynasty with a basin area of 240 Sq.Km to fulfil the drinking water requirements of the people. The water in the lake was reasonably good till 1976.
Over the years, Hussain Sagar Lake has become polluted through entry of untreated sewage and industrial effluents through the nalas that flow into the lake. As a result, nutrient rich sediments accumulated in the lake bed which in turn acted as an internal source for supply of nutrients to the Lake water. Other sources of pollution included cattle washing, vehicle washing, dumping of domestic solid waste along the shore line as well as the immersion of large numbers of Ganesh and Durga Idols during festivals containing paints, clay, gypsum and plaster of Paris, flowers and garlands.
Issues affecting the Hussain Sagar Lake:
There are four major Nalas through which domestic sewage, industrial effluents and other debris enter the lake.
