The Kathmandu Valley Water Supply Management Board received countless reports of water shortages and the drying up of wells, borewells, and tube wells.
FREMONT, CA: The Valley's groundwater is being reduced for a variety of causes, including uncontrolled groundwater, shrinking open spaces, months without rain, black-topping, and the capacity to enclose roads and open spaces near residences.
The last of three deep borewells at the Tribhuvan University Teaching Hospital in Maharajgunj dried out five months ago. One of the other two went offline nearly seven months ago, and the other approximately eighteen months ago. All three borewells were more than 300 feet deep. One of them was drilled when the Japanese built the hospital forty years ago. Its water supply has now been withdrawn. Borewells and tube wells are drying up in the Kathmandu Valley. Over-pumping of groundwater, shrinking open spaces, months of little rain, black-topping, and concretisation of roads and open spaces near buildings, according to experts, are among the causes of groundwater depletion in the Valley.

The Kathmandu Valley Water Supply Management Board received multiple reports of wells, borewells, and tube wells drying up and groundwater depletion. Many locals have also expressed concerns about physical damage to their homes as a result of extensive groundwater extraction by nearby manufacturing and businesses. The drying up of deep borewells on the hospital grounds during the monsoon, according to experts, is concerning because aquifers recharge during the rainy season. The Tribhuvan University Teaching Hospital updated the water pumps and cleaned the borewells, however, these steps did not improve water pumping. Once the deep borewells dried up, two smaller borewells were erected on the hospital grounds, but only one of them could be accessed by submersible pumps.
Patients do not drink muddy water, and it is equally unreasonable to expect them to drink whatever water flows from hospital faucets. The wastewater also damaged medical equipment. Dialysis membranes must be changed frequently due to the unclean water.
The Kathmandu Upatyaka Khanepani Limited has linked a three-inch pipeline to the hospital at the request of the hospital, which treats thousands of patients every day, but the problem is that the utility does not supply water on a regular basis.
As reported by the Kathmandu Valley Water Supply Management Board, dry wells, tube wells, and borewells have harmed several institutions and the general public. A prior investigation by the hydrogeologist revealed that groundwater in Kathmandu Valley was decreasing. The northern half of the valley, comprising the Budhanilkantha and Tokha districts, has fewer problems, but depletion is severe in the valley's centre.
