South Fork Rivanna Reservoir (SFRR) to Ragged Mountain Reservoir (RMR) Pipeline, Pump Station, and Intake Construction Project.

The South Fork Rivanna Reservoir to Ragged Mountain Reservoir Pipeline, Pump Station, and Intake Construction Project will hydraulically connect two local reservoirs. The project marks the final component of the 2012 Community Water Supply Plan, a ten-year planning effort that was initiated after the region experienced a drought of record in 2002. The plan, approved in 2012, called for a significant investment in our community’s drinking water infrastructure to include increasing the storage capacities of the Ragged Mountain Reservoir, replacing the existing raw water pipelines and pump stations connecting the Ragged Mountain Reservoir and Observatory Water Treatment Plant, constructing a new raw water pipeline, intake, and pump station to connect the South Fork Rivanna and Ragged Mountain Reservoirs, and renovating the South Rivanna and Observatory Water Treatment Plants. The plan was crafted regionally in collaboration with the Charlottesville City Council and the Albemarle County Board of Supervisors, with input from many community groups.

The South Fork Rivanna Reservoir to Ragged Mountain Reservoir Pipeline, Pump Station, and Intake Construction Project includes 6.5 miles of 36″ raw water pipe that will be installed from the South Fork Rivanna Reservoir to the Birdwood Golf Course. The pipeline’s path will follow along Woodburn Road, Rio Road W, Hydraulic Road, Lambs Road, Colthurst Drive, and Old Garth Road. The new raw water intake and pump station will be built near the South Rivanna Dam and when complete, will have the capacity to pump 41 million gallons of water per day. Supporting water infrastructure allows for the potential to transfer 25 million gallons of water per day from the South Fork Rivanna Reservoir to the Ragged Mountain Reservoir, including up to 10 million gallons of water per day from the South Fork Rivanna Reservoir to the Observatory Water Treatment Plant, and 16 million gallons of water per day to the South Rivanna Water Treatment Plant.

Benefits

• 

  Two of RWSA’s urban water treatment facilities will be able to draw water from either reservoir, providing an additional layer of redundancy.

• The new water line allows raw water to be transferred between reservoirs. This infrastructure upgrade enables RWSA to fully utilize South Fork Rivanna Reservoir’s 259 square mile watershed and Ragged Mountain Reservoir’s 2.1* billion gallon water storage capacity.
• The project will allow RWSA to retire a 100-year-old raw water pipe that currently connects the Sugar Hollow Reservoir to the Ragged Mountain Reservoir. This 18″ water pipe has a maximum transfer rate of 3 million gallons of water per day, which is significantly less than the 25 million gallons of water per day that the new SFRR to RMR water pipe will be able to handle. Once decommissioned, water stored in the Sugar Hollow Reservoir may be released into the Moormans River and Mechums River during drier months to maintain the South Fork Rivanna Reservoir’s reserves. The open method of transfer can help raise river water levels downstream of Sugar Hollow during drought periods.
• A new water boom will be installed across the reservoir to improve recreational watercraft safety above the dam. The boom provides a physical barrier that prevents reservoir users from getting too close to the dam.

Project Schedule

A tentative schedule is currently being worked on. Updated information will be published here when available.

Working Hours

To minimize traffic impacts, VDOT requires that construction along Rio Road E, Hydraulic Road, and Ivy Road occur at night. Outside these areas, general work hours will be Monday through Friday from 7:00 AM to 6:00 PM. Weekend and night work may occur if approved in advance by RWSA.

Construction Activities

Construction sites are active environments where many tasks occur. A passerby may notice workers, equipment, materials, and changing conditions as the project moves forward. Each visible element plays a role in the overall process, and together they show how planning, coordination, and skilled effort turn designs into functional infrastructure.

Paint markings and flags are used early on to identify existing utilities and future work areas, helping crews visualize the work before excavation begins. Surface pavement is then saw cut using large, powered equipment to create clean, controlled openings that minimize disruption and allow access to the underlying soil. Test pits, or small exploratory holes, are dug ahead of major excavation to confirm the precise location of existing utilities. As progress continues, a mobile convoy of excavators and dump trucks works along the pipeline alignment to install pipe. When permissible, steel plates are placed over open areas during non-working hours to protect the public. When steel plates are not allowed, open pits are backfilled. Temporary pavement restoration occurs after the mobile convoy has advanced. Final milling and paving will occur periodically throughout the project to restore roadways to their preconstruction condition.

Temporary Trail Impacts

Temporary trail closures are expected around Albemarle High School, Journey Middle School, Greer Elementary School, and UVA Foundation’s Westover Property. These closures are meant to protect individuals from construction activities. Trail signage will provide advance notice prior to the closures. This project will be closely coordinated with Albemarle County Public Schools and UVA Foundation to complete the work and restore access to the trails as quickly as possible.
