The Adil Shahis of Bijapur, well known for their able administration and love for music, were also recognised for the excellent water supply schemes that
they implemented. There is much historical evidence to show that they possessed deep knowledge about water harvesting. Infact they did not look upon water as a mere daily necessity, but also as a luxury commodity to indulge in water sports. The water was collected in the hills outside Bijapur and supplied to the inner parts of the city through tunnels to bavadis. Historians confirm that the density of population in Bijapur was so high during the reign of Ibrahim Adil Shah II and Mohammed Adil Shah that the city probably consumed double the quantity of water it needed.
Bavadis are another term for a well. There are a number of bavadis here such as Tajbavadi, Chand bavadi, Ibrahimpur bavadi, Nagar bavadi, Mas Bavadi, Alikhan bavadi, Langar bavadi, Ajgar bavadi, Daulat Koti bavadi, Basri bavadi, Sandal bavadi, Mukhari Masjid bavadi, and Sonar bavadi etc. In fact, the list is very, very long. Of these, the Taj bavadi and the Chand bavadi are the biggest and attract tourists due to their artistic excellence. While Taj bavadi, with its size and grandeur, occupies the first place, Chand bavadi and Ibrahim bavadi occupy the second and the third places respectively. People of the city still use the 30 bavadis that exist today.
