PC Construction and HDR Constructors recently joined Virginia Governor Terry McAuliffe and officials from Hopewell Regional WWTF Alternative 4A-1 Light Phase 2 Nitrogen Removal Improvements project to break ground for a $76 million Alternative 4A-1 Light Phase 2 Nitrogen Removal Improvements project.

The design-build project will increase treatment capacity from 27 mgd to 46 mgd while simultaneously reducing nitrogen contained in its discharge released into the James River, a primary tributary to the Chesapeake Bay.

According to an announcement on the PC Construction website:

... Speaking about the enhanced facility, Governor McAuliffe said, “This project is a fantastic example of how Virginia businesses and industries can work in partnership with localities to improve the quality of our water. Hopewell has been able to attract industrial growth and expansion because of this regional facility, and this new project will ensure a tremendous impact on the local and regional economy.”

Others participating in the groundbreaking ceremony included Secretary of Natural Resources Molly Ward, Secretary of Commerce and Trade Maurice Jones, Hopewell City Manager Mark Haley, and Plant Superintendent Jeanie Grandstaff.

The joint venture team of PC Construction and HDR Constructors began preliminary work on this design-build project late last year. The scope of the project will increase treatment capacity from 27 mgd to 46 mgd and reduce nitrogen contained in its discharge – which is released into the James River, a primary tributary to the Chesapeake Bay – to meet permit limitations for total nitrogen loading and ammonia concentrations. The joint venture team will incorporate the Moving Bed Biofilm Reactors (MBBR) technology to provide the most reliable level of treatment for the unique and unbalanced influent flow characteristics processed by the facility. The efforts will help preserve water quality and provide a clean habitat for sea life and waterfowl in the largest estuary in the United States.

Completion of construction is scheduled for early 2017.
