Duchesne Valley Water Treatment Plant

The Duchesne Valley Water Treatment Plant is located east of the Starvation Dam and distributes water to customers through over 50 miles of pipeline.

This plant serves Myton, Duchesne City, East Duchesne, and Johnson water. With a capacity of eight million gallons a day, this plant treats water form Starvation Reservoir.

Starvation Reservoir is the water source for the plant. Strawberry River is the major inflow to the reservoir, but water is diverted from the Duchesne River, at times through Knight Diversion. Water quality in both sources is very good with only seasonal exceedences of water quality criteria. The watershed is large with very remote areas.

A cooperative watershed management program was initiated in the early 1990's to assess possible future impacts on the reservoir. Impacts were largely due to recreation, sedimentation, and widespread grazing. The major tributary streams are monitored by the Utah Division of Water Quality.
