PM USA operates the Park 500 tobacco processing facility on the James River, Virginia. The facility has a design capacity of 11 ML/d (2.9 mgd) of secondary treated wastewater to the river, but current daily flows average 4.3 ML/d (1.14 mgd). In 2005, PM USA elected to implement a constructed natural treatment system to reduce nitrogen and phosphorus loads into the river. After an initial feasibility assessment, a 15-ha (42-ac) free water surface wetland was designed, constructed, and brought into service in July 2008. After 2 years in operation, this system has yielded measurable reductions in nitrogen and phosphorus loads into the James River while creating a productive wetland habitat. The design-build delivery method of the project provided an effective and expeditious approach to project implementation and has made this project a significant milestone in the application and acceptance of natural treatment systems in Virginia and worldwide.
