Meadow Creek Interceptor Project
What is the Meadow Creek Interceptor
The existing Meadow Creek Interceptor is approximately 22,800 linear feet of pipe and was built in the 1950s by the City of Charlottesville. Its purpose was to transport wastewater from sewer lines serving land within the Meadow Creek watershed to the old Meadow Creek Wastewater Treatment Plant located near Penn Park Lane.
The City of Charlottesville conveyed the Meadow Creek Interceptor to the Rivanna Water & Sewer Authority (RWSA) in 1973 when RWSA was created through a four-party agreement. Later when the construction of the Rivanna Interceptor was completed by RWSA, the Meadow Creek Interceptor was connected to the new Rivanna Interceptor to transport flows to the expanded Moores Creek Wastewater Treatment Plant. The City's Meadow Creek Wastewater Treatment Plant was then decommissioned. Today the Meadow Creek Interceptor transports an average of 4-5 million gallons per day of wastewater.
The existing Interceptor Sewer Pipe consists of 21" to 36" diameter of clay pipe, clay tile lined concrete pipe and ductile iron pipe stream crossings.
About the Project
Rivanna Water & Sewer Authority, partnering with the City of Charlottesville and the Albemarle County Service Authority, is preparing to upgrade the Meadow Creek Interceptor, a large-diameter sewer pipe serving the eastern part of the City of Charlottesville and the urban ring of Albemarle County. Through working together, the parties have established realistic goals to meet the environmental needs of the community, while upgrading the aging infrastructure that is crucial to reliable, uninterrupted sewer services.
In a consolidated strategy by the Authority, City, and County, the main goals for the Meadow Creek Interceptor upgrade are environmental ones, in both preserving and elevating the quality of the area's water resources, and working alongside the City's project to restore Meadow Creek back to its natural pattern.
The existing Meadow Creek system is more susceptible to breakage due to its age and undersized capacity, which in turn necessitates costly repairs. Due to the urbanization of the areas surrounding Meadow Creek, the character of the stream has changed, which causes erosion around the pipes and unsightly conditions to residents. Additionally, there has been increasing storm water infiltration, which stresses already maxed-out pipes, and creates the need to chemically and physically treat rainwater the same as sewage, adding to costs, use of chemicals, and additional nutrient discharge back into the environment. This project is being coordinated with efforts by the City and the Albemarle County Service Authority to aggressively reduce stormwater infiltration, and the size of the pipeline was selected to facilitate short-term environmental remediation and long-term economics.
