Project Description (Updated 10/25/2022)

The Service Authority’s award-winning H.L. Mooney Advanced Water Reclamation Facility (AWRF) in Woodbridge treats up to 24 million gallons of wastewater per day, meeting or exceeding federal and state standards. After treatment at Mooney AWRF, the reclaimed wastewater is released into Neabsco Creek, a tributary of the Potomac River.

This infrastructure project is designed to improve operational resiliency and levels of service, provide additional odor control and allow the plant to continue meeting regulatory requirements. Project elements will include enhancements to several areas of the Mooney facility: primary clarifier odor control upgrade; primary clarifier collection equipment upgrades; primary clarifier electrical improvements; equalization basin modifications; Return Activated Sludge Building pump modifications; additional Ultraviolet Building equipment; yard valves replacement; methanol storage addition; lime system upgrades; ferric system improvements; secondary clarifier improvements; plant structural protection and refurbishment; and polymer system replacement.
