Fountains and gardens are nothing new to Hyderabad. Gulzar Houz, Katora Hauz, and Langar Houz are still the location markers in the city as are Amin Bagh, Bagh Lingampally, and Aam Bagh. Plants in these gardens were watered and the fountains operated all without electricity, as the garden planners used the magic of the undulating terrain of the Deccan Plateau to chisel out exquisite gardens.
A few kilometers away is the Hayatnagar Masjid which was built by Hayat Bakshi Begum. It shows the inner working of fountains and water channels. Just outside the masjid is the Hathi Bowli. “It is believed that elephants were used to draw water to fill the overhead tanks. There are clay pipes that carried the water to the tank in the northeast corner of the masjid. The water would be under sufficient pressure to rise to the ablution tank as well as power the fountain,” informs Mr. Shahid These engineering marvels are not limited to the Qutb Shahi and Asaf Jahi eras. The Bagh-e-Naya Qila inside the Naya Qila of the Golconda Fort incorporated Kakatiya-era water structures including platforms for leisure. Now, these can be spotted as grassy knolls in the lake of Hyderabad Golf Club. On the other side of the lake was the quadripartite (Chahar bagh) with a stream running in the middle. Remains of the pipelines that helped create the fountains exist on the left side near the garden pavilion.
