Project Overview

This $71.6 million project upgraded the facility to ensure the plant meets new nutrient reduction requirements and nitrogen limits in the Chesapeake Bay watershed. Improvements included a segregated treatment process, Moving Bed Biofilm Reactors technology, Dissolved Air Flotation, fine screens, three pump stations, aeration blowers, chlorine contact tanks, caustic and acid storage and feed, and polymer storage and feed. The facility received a complete electrical upgrade to 34.5kV high-voltage electrical system with power monitoring.

Extensive excavation and groundwater dewatering was required for the new structures. PC’s creative problem-solving saved $14 million in capital construction costs and will decrease ongoing operational costs by $500,000 annually.
