The Hussain Sagar Tank is only visible on the map. The Hussain Sagar Tank was constructed by the Ibrahim Qutub Shah, the fourth Qutub Shahi Sultan in 1562 A.D for the purpose of solving drinking water issue. Initially, its name was Ibrahim Sagar, but Since the construction was supervised by his son-in-law namely Hussain Shah Wali, who was then the superintendent of Public Works, people began to refer it as Hussain Sagar. It says that when Sultan came to know that Tank was popularly known as Hussain Sagar, immediately he constructed another tank known as Ibrahimpatnam Tank. Until 1925, the Hussain Sagar Tank served as the source of drinking water to the then suburbs Khariatabad and Saifabad. Since the Tank cover an area of 21 K.M, the Bund lies between Hyderabad and Secunderabad. Now the water body is no longer in use due to the pollution. The Tank fed by a canal runs about km in length diverted from the river Musi.
