A multiple-use water system (MUS) is a combined water facility that has proven useful as a means of providing drinking water and water for irrigation for smallholder farmers in the hilly areas of Nepal. Water is collected by gravity from a highland source into a holding tank and is shared by means of distribution lines, domestic tap stands, and irrigation off-take lines. It can also support application of micro-irrigation technologies (MIT) such as drip and micro sprinkler irrigation systems.
