Motts Run Water Treatment Plant

The Motts Run Water Treatment Plant was constructed to meet the growing demand within the County and to replace the aging City of Fredericksburg’s Athur L. Cossey Water Treatment Plant. The Motts Run Treatment Plant was built in the late 1990s and went online as a 12 million gallons per day (MGD) water treatment plant with the potential for final build-out of 24 MGD. The Motts Run Water Treatment Plant has two main source waters, the Rappahannock River and Motts Run Reservoir. During low river flow or high demand, the Motts Run operations staff can supplement flows with releases from Hunting Run Reservoir into the Rapidan River, which flows to the Rappahannock River and is withdrawn at the Motts Run intake.
