Cub Run Sewer Project
The Upper Occoquan Service Authority (UOSA) is preparing to replace approximately 26,000 linear feet of sewer pipelines in the Cub Run Gravity Delivery System (CRGDS). The CRGDS serves Western Fairfax County, delivering raw sewage to the Cub Run Pump Station. Constructed in the 1970s, the CRGDS is located within Cub Run Stream Valley Park, part of the Fairfax County Park Authority (FCPA) system. The purpose of this site to inform residents of the affected community about the construction project and receive comments from the public.
WHY IS THIS PROJECT NECESSARY?
The reinforced concrete pipe originally used to construct the CRGDS is exhibiting signs of deterioration typical of unlined wastewater pipes over 30 years old. Additionally, as result of the population growth inWestern Fairfax County since the pipeline was constructed, the CRGDS does not have the capacity to adequately handle the peak flow of wastewater currently being generated. Combined, these two factors significantly increase the risk of wastewater overflow, potentially causing significant environmental problems and service interruptions.The new pipeline will be constructed to accommodate future population density under current zoning laws and high flows during storms. The improvements will extend from just north of Braddock Road (Rte. 620) to just north of I-66
|ALTERNATIVES Other pipeline location alternatives were examined; however, it has been determined that this “in-place” approach would minimize rock removal, limit disruption to the community, and limit impacts to the environment. It is not feasible to build this project in another location.|
