Accotink Gravity Sewer Improvements Project

Project # WW-000032-027

Project Update: May 31, 2022

Fairfax County Department of Public Works and Environmental Services hosted an informational meeting about the Accotink Gravity Sewer Improvements Project on Tuesday May 24, 2022, at 7 p.m. 

The goal of this project is to increase the capacity of the sewer system to accommodate the planned growth in northern Fairfax County and to ensure the sewer system continues to provide continuous reliable service to all customers.

Project Background

The Fairfax County Department of Public Works and Environmental Services, which is responsible for wastewater collection and treatment in Fairfax County, is working on several wastewater infrastructure projects to collect and treat the additional wastewater that is anticipated to come from the northern parts of Fairfax County. The Accotink Gravity Sewer Improvements project is one of these projects. The goal of the project is to increase the capacity of the sewer system to accommodate the anticipated growth in the northern Fairfax County area and to ensure the system continues to provide continuous reliable service to all customers. Since it can take a considerable amount of time to effectively plan, design, construct, and bring these types of facilities online, the county is working on improvements now to stay ahead of these capacity needs.

Project Description

The county has been studying future flow projections for the northern Fairfax County area and has compared these projections to current available capacity. The studies show that facilities in the northern Fairfax County area have insufficient capacity to handle future flows. The studies concluded there is capacity to treat these flows at the county operated Noman Cole Pollution Control Plant, in Lorton VA. Capacity improvements in the sewer collection system are needed to modify and expand the capacity of the existing sewerage system to allow the flows to be transported to this plant for treatment.

Planning activities for this project have been completed and the selected plan will involve the construction of approximately 15,000 feet on new sewer pipe which will be integrated with the existing sewerage system to provide the capacity needed.

Project Phase

The project is in planning phase.

Timeline

Planning Summer 2021 - Summer 2022
Design Summer 2022 - Spring 2023
Construction Completes Spring 2025

What to Expect

Area residents, business owners, and other key stakeholders located near the selected pipeline route will have an opportunity to hear a presentation on our planning process and provide input on the selected route. The county will publish information from this presentation on the project website. The project will be transitioning into design related activities soon. During design, more specific information will be developed for the project and the county will continue with a public outreach program and will begin to target specific stakeholders who may be directly impacted by the project. Once the design has been finalized and the project begins to transition into construction, the public outreach program will continue to provide construction related information.

Project Cost and Funding Source

The estimated cost for this project is approximately $37 million. The project is being funded through Sewer Use fees and Availability Charges which are assessed when new connections are made to the system.

Presentations to the Community

A virtual public meeting to review the project and answer questions from the community was held May 24, 2022.
