KATHMANDU, June 21: The Melamchi Water Supply Development Board (MWSDB) has decided not to immediately shut down the main source of the Melamchi Drinking Water Project located in Ambathan, Sindhupalchowk, despite earlier preparations to halt operations from today. This decision comes in response to the inadequate water flow in the Melamchi River starting today, prompting the committee to exercise caution in distributing water to the designated areas.
