Construction is complete and the ribbon is cut for the new Accotink Odor Control Facility at the Noman M. Cole, Jr., Pollution Control Plant in Lorton, Virginia.
The completed project modernizes key systems across the site, beginning with a new odor control system designed to significantly improve the quality of life for nearby residents. The system includes an inline pre-filter, a pre-engineered bio-trickling filter system, and an activated carbon adsorber. The system strengthens odor management and supports ongoing compliance – an important component for facility operators and the surrounding community.
Operational efficiency was further enhanced with the construction of a prefabricated waste manifest building. In addition, new electrical panels were installed within the existing control building and 1,200 linear feet of underground electrical duct bank was incorporated, delivering updated infrastructure to support the facility’s upgraded systems and future upgrades.
Significant mechanical improvements were completed throughout the site, including the replacement of instruments, valves, actuators, and electrical equipment within two 150-cubic-foot septage receiving tanks. These improvements increase reliability and safety while reducing long-term maintenance demands.
Environmental protection was a focus of the project. A new stormwater diversion swale was installed to better manage runoff and protect surrounding areas. Spill containment was also enhanced through the installation of a new trench drain system and piping designed to contain and control potential releases. Erosion and sediment control measures were implemented throughout construction to protect site conditions, including super silt fencing and tree and inlet protection.
The project concluded with finished sitework that restored and improved access throughout the facility.
We are grateful for our continued partnerships with Fairfax County and Hazen and Sawyer and are proud of our collective efforts to deliver improvements designed to support reliable operations, meet evolving environmental standards, and serve the community well into the future.
