KATHMANDU: Collection of rainwater on 300 square kilometers area alone would be enough to meet the water needs of Kathmandu for 525 days.
According to geologist Dr Suresh Das Shrestha, if the run-off water was to be collected in ponds or by constructing recharge wells without letting that drain off, it could go a long way in alleviating the acute water shortage in the capital.
Dr Shrestha said annually 30 million litres of water could be collected at the pond at Bhikhel, Swayambhu if only 15 percent of the rainwater in the Swayambhu area could be collected.
Currently rainwater is collected at a pond at Bhikhel on the east side of Swayambhu by constructing drains in a systematic way.
Two wells with a diameter of some 12 feet have been constructed for recharging the groundwater, Dr Shrestha said. He stressed that water will automatically start filling the wells at homes in the area once the aquifer is recharged.
He said a project to recharge Kathmandu's groundwater through rainwater harvesting is underway through the joint initiatives of UNDP and the Integrated Urban Development Centre.
