Hussain Sagar lake
Andhra Pradesh

Hussain Sagar Lake is one of the largest man made lake situated at the confluence of Hyderabad, Secunderabad and Begumpet. It is a sprawling artificial lake that holds water perennially. Its uniqueness lies in the fact that it connects the twin cities of Hyderabad and Secunderabad. The lake was built in the year 1575 by Sultan Ibrahim Kutb Shah at a cost of about Rs. 2.5 lakhs. The lake was originally constructed to supply drinking water but it is not used as a drinking water source since 1930. The lake also protected the citizens staying in the low lying areas around the lake from floods.

The main threat to the lake is encroachment by both private and public agencies. In the past 30 years, the lake has shrunk about 40 % of its original size (550 ha to 349 ha). In addition to the encroachment the lake also faces the problem of pollution due to the continuous discharge of untreated domestic sewage and toxic industrial chemicals for several years. Although several Central Effluent Treatment Plant and Sewage Treatment plant have grown up to restrict the pollution yet a considerable amount of sewage flows into the lake.


To save the lake, the Forum filed several PILs in the High Court of Andhra Pradesh (AP) since 2001. The last PIL was filed in 2004 in the High Court and the judgment is still pending. PIL was also filed under Special leave petition in Supreme Court by another environmentalist Dr. Haragopal in the year 2005. Environmentalist Radha Bai also filed a fresh PIL in the year 2006 to stop pollution in the lake. Crores of rupees have been sanctioned for the revival of the lake but the lake is still in a very poor state. HUDA promises to make the lake pollution free by 2010.


Several PILs have been filed to save the Hussain Sagar Lake. All the PILs are under the consideration of the HC of Andhra Pradesh and SC of India. The followings are some of the highlights:
