With groundwater supplies drying up, harvesting rainwater could help ease the water crisis in the Bangladeshi capital. Rainwater could potentially supply about 15% of the city's water requirements.
Dhaka is currently largely dependent on groundwater for its drinking water, but supplies are depleting rapidly. The city's Water and Sewerage Authority (WASA) has the capacity to produce up to 1800 million litres a day, while demand is in excess of 2000 million.
A study carried out by the Institute of Water Modelling (IWM) suggests that around 150,000 million litres of rainwater could be harvested during the annual monsoon. "The water that goes down the drain and causes waterlogging every year can serve a better purpose," says Mizanur Rahman, senior hydrogeologist at the IWM. He added that, apart from being used for drinking water, harvesting rainwater could also help to conserve groundwater and recharge the water table.
A pilot project will be implemented on the roofs of WASA buildings, in parks and open spaces, and on university campuses. Plan Bangladesh and Coca Cola have also initiated a pilot project to harvest rainwater at five schools in Dhaka and Barguna district.

Rain water harvesting is very good idea to reduce water shortage in big cities.
