Source Water means an untreated source of water used to supply drinking water to the general public. For example, source water is groundwater before it is pumped out by a well and surface water flowing to or in the Truckee River before it is diverted to one of Truckee Meadows Water Authority (TMWA) treatment plants. Source Water Protection Area represents an area where the community has established a precautionary boundary to safeguard the water quality of its drinking water sources.
