The over-extraction of groundwater in the Kathmandu Valley is a serious issue that can lead to high-range negative consequences. The depletion of natural recharge capacity can result of the lowering of the water table, which can cause wells to dry up and make it harder to extract water.The government, along with the public and private sectors, can work together to develop and implement effective policies and strategies to ensure the sustainable use of groundwater resources in the Kathmandu Valley. The amount of groundwater extraction In Kathmandu Valley is 21.56 MCM per year, which is more than its natural recharge in the range of 4.6–14.6 MCM/year.
The main objective of this study was to determine the amount of groundwater recharge by urban parks or the amount of groundwater recharge by rainwater of plant ecology by a natural process based on the literature review.
However, the possible techniques use well-shaped structures to infiltrate water into a deep aquifer. Besides recharging well, LMC has used surface runoff water to percolate through the natural infiltration media. Introducing green parks improves soil quality, increases the soil's infiltration capacity, and converts the impervious surface into the previous surface to recharge Groundwater. This method is more economical and ecological for urban human life and other local habitats.
