Project Description

The Service Authority’s award-winning H.L. Mooney Advanced Water Reclamation Facility (AWRF) in Woodbridge treats up to 24 million gallons of wastewater daily, 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 service levels, provide additional odor control, and allow the plant to continue meeting regulatory requirements. Project elements include enhancements to several areas of the Mooney facility: primary clarifier odor control upgrade; primary clarifier collection system improvements; primary clarifier electrical improvements; equalization basin modifications; Return Activated Sludge Building pump modifications; additional Ultraviolet equipment; yard valves replacement; supplemental carbon system improvements; alkalinity system upgrades; ferric system improvements; secondary clarifier improvements; plant structural protection and refurbishment.

The H.L. Mooney Advanced Water Reclamation Facility Wide Improvements Project groundbreaking ceremony was held on December 6, 2023.
