Islamabad: The Capital Development Authority (CDA), in an effort to replenish groundwater supplies as the water table in the capital continues to decline by at least four feet per year, has planned to mandate that home owners build recharge wells to collect rainwater.
The construction of recharge wells at the home level will be implemented with the goal of recharging groundwater aquifers for a longer period of time and with good results, according to a proposal that has been submitted to the building control section of the CDA.
The owners of dwellings are already required under the current by-laws to build water tanks to store rainwater, however these by-laws are not enforced.
The Deputy Director General stated, “Groundwater is disappearing fast at an annual pace of four feet, so we will enforce implementation of these by-laws for the installation of water tanks and construction of recharge wells.
A CDA official claimed that at least 70 underground wells that have been built in various locations, notably parks, have contributed to raising the local subterranean water table.
No additional water sources have been investigated to supply the city’s water needs since the Khanpur Dam was built in the 1990s. Around 600,000 people called the city home at the time; today, that number is thought to be closer to three million.
