A portion of Hussain Sagar Tank, south of it, state Mint Department and in between a railway track laid out horizontally are 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. It was in 1905 A.D, the State Mint moved to the Saifabad palace of Nizam by the then Finance Minister of Nizam govt namely Sir George Casson Walker, who credited in establishing an up-to-date mint and replaced previous hand-made coin and introduced newly machine-made coins. Initially, the department confined to the Mint, but since 1912 A.D the department has undertaken works from the other departments includes the manufacture of seal, badges, stamps, engraving, and die-making etc. Along with Mint and Finance, the palace occupied the Public Works and Political Department also. And a residential settlement is also visible to the left side of the Hussain Sagar Tank
