The document summarizes water supply and markets in Kathmandu Valley, Nepal. Water demand is increasing steadily but the main utility can only supply 105 MLD in the wet season and 75 MLD in the dry season. To meet additional demand, commercial water extraction and vending using water tankers has grown to supply over 25 MLD in the peak dry season. Water is extracted from over 40 locations in peri-urban areas. There is debate around how to regulate the growing groundwater market between supporting it as a supplement to utilities versus seeking to limit extraction and discourage the market.
