Alexandria Nutrient Management Facility to Improve Health of Local Waterways

ALEXANDRIA, Va.– Alexandria Renew Enterprises, which operates water reclamation facilities serving 350,000 residents in Northern Virginia, selected Clark Civil and joint venture partner Ulliman Schutte Construction (Clark/US, LLC) to oversee construction of a Nutrient Management Facility (NMF). The 100,000 square-foot NMF is a key part of Alexandria Renew's State-of-the-Art-Nitrogen-Upgrade Program and will help reduce the amount of nitrogen from wastewater destined for the Potomac River and Chesapeake Bay.

Under a Construction-Management-at-Risk contract, Clark/US, LLC, will construct the NMF, which will provide additional storage tanks totaling 18-million gallons and extending 30 feet below grade. In addition, the team will connect the NMF to the adjacent, existing wastewater treatment facility; install a pump station, odor control system, and the electrical facilities to power the new equipment; and relocate existing overhead, high-voltage electrical distribution lines below ground to facilitate construction of a new bridge and roadway over an adjacent stream crossing. Once the NMF work is complete, the Clark/US team will construct a regulation, artificial athletic turf soccer field above it and install other related amenities for public use.

Construction will commence in March 2013 and completion in scheduled for early 2015.

CH2M Hill, Washington, D.C., is the lead engineer.
