Kathmandu's perennial drinking water shortage has erupted as a major crisis this year, the driest in recent times with only one-third of the current demand of 180 million liter per day being met. According to G B Amatya, the manager at the Nepal Water Supply Corporation (NWSC), the corporation is supplying only 55 to 60 mld. Even during the monsoon, the corporation has the capacity to meet only 90-95 per cent of the demand.
