In one monsoon season, over 33 lakh litres of water was collected in the baoli, which now also holds a large fish population. This resulted in the mapping of water flow within the Qutb Shahi Heritage Park, regarding earth where required and providing underground drains where required. A collection chamber created to the west of the baoli was drained into the baoli from beneath the arcade in order to ensure rainwater does not exert stress on the masonry. The collected water will be used for irrigation and conservation works for the duration of the year.
To ensure water does not drown the newly reconstructed water, pumps were used to shift collected water to another baoli after the 33 lakh litres holding capacity was exhausted. Teracotta pipes discovered during archaeological investigations have revealed that a similar system was in place in the 16th century when the various baolis in the complex were interconnected.
