Water Sources & Facilities

The Town of Erie's primary water source is the Colorado-Big Thompson Project (C-BT), which originates on the western slope and is delivered via pipeline from Carter Lake in Berthoud to our Lynn R. Morgan Water Treatment Facility in Erie. C-BT water is also delivered via pipeline to our reservoirs for storage in Erie. Windy Gap is a secondary water source which is delivered to Erie from the Northern Colorado Water Conservancy District (NCWCD) via a pipeline to the Water Treatment Facility.

We also fill our reservoirs via the South Boulder Canyon Ditch which originates from Gross Reservoir in Boulder. There are pipelines that carry water from our reservoirs directly to our Water Treatment Facility. Potable water is distributed from the water treatment facility to customers.

Lafayette Water and Lefthand Water are constant connections that are only used in emergency situations.
