Hunting Run Water Supply Project
Spotsylvania County, Virginia
Client: Spotsylvania County, Department of Utilities
Spotsylvania County, VA, has rapidly outgrown its water system due to a five percent annual population growth over the last two decades. The adjacent City of Fredericksburg also faced major upgrades to its water treatment plant. In cooperation with the City, Spotsylvania County assumed the role of primary regional purveyor, requiring a comprehensive system expansion and upgrade. Our firm provided engineering services for the design, bid, construction, testing, and monitoring phases of the projects.
The original project included a 6 mgd water treatment plant, dam and associated pipelines. To accommodate regional service, the revised program included the design and construction of the 12 mgd Motts Run Water Treatment Plant and Transmission Mains, Hunting Run Dam and Reservoir, two river intakes and pump stations, and modifications to Motts Run Dam to convert it to a pumped storage facility. These projects were constructed to provide additional treatment capacity and raw water supply and will allow Spotsylvania County and the City to support future growth without moratoria. The supply of safe, reliable drinking water will continue without rationing during drought periods.
- Actiflo® system, first of its kind in VA, used in the water treatment plant
- Redesigned plant to fit in with surroundings
- Plant Expandable up to 42 mg of water per day
- Improved existing spillway and embankment of the dam to prevent flooding
- New embankment blanket and toe drain systems control seepage through dam.
- Dam constructed using more than 142,000 cubic yards of roller compacted concrete and 500,000 cubic yards of earthfill with zoned earthfill embankments at each end
- IntelliGrout(TM) used for the dam - a revolutionary computer system initialized for real time electronic monitoring and recording of the production grouting
- Reservoir covers 420 acres, contains 3.1 billion gallons of water, and provides an additional eight mgd of water supply to Spotsylvania County.
