Water Sources & Facilities
Erie's existing water supply consists of ditch, reservoir, Colorado Big-Thompson (CBT)2, and Windy Gap3 surface water supplies. Raw CBT and Windy Gap water are delivered to Erie from the Northern Colorado Water Conservancy District (NCWCD) via a pipeline to the potable water treatment facility in the southwest portion of the service area. Erie's storage reservoirs (Erie, Prince, and Thomas Reservoirs) are also in the southwest portion of the service area.  Raw water pipelines convey this water to the potable water treatment facility and to/from Thomas Reservoir. Potable water is distributed from the water treatment facility to customers.
