UOSA Water Reclamation Facility Improvements

Fairfax County, Virginia

RDA has provided civil engineering services and permitting assistance to UOSA for over 2 decades.  Most recently, RDA has been assisting a prime consultant in site/civil design and permitting for a new Ozone Biofiltration (OBF) system improvement project.  To prepare for the OBF improvements, a separate project to demolish buildings and infrastructure for the existing Ammonia Removal and Recovery Process (ARRP) onsite was required.  RDA prepared a rough grading plan and obtained all related site permits/approvals through Fairfax County to allow for the demolition of the ARRP infrastructure.  A separate site plan was then prepared and permitted through Fairfax County for the OBF improvements.  Removal of the ARRP infrastructure was completed in 2021 and construction for the OBF improvements is currently anticipated to begin in Summer 2024.
