ABSTRACT
Dhaka, Bangladesh’s capital is one of the foremost inhabited megacities of the globe. Management and development of sustainable and safe water supply for the city dwellers are completely dependent on ground water and river water availability. The previous years, it has been reflected that Dhaka city experiences water shortage in some areas during the dry season Rainwater harvesting can be an efficient strategy for reducing the present water crisis and minimizing the findings of climate change on water supplies. This study uses rainfall data and the roof surfaces of both residential and business structures to show how rainwater harvesting in Dhaka City could provide a source of potable, clean water. Average rainfall varies from 157 mm to 311 mm in the rainy season. It is found that a maximum of 21% percent of the present water supply can be covered by rainwater harvesting during monsoon.
Keywords: Water crisis, Water supply, Scenario of rainwater, DWASA’S, and Rainwater harvesting.
