Join WateReuse Ohio to learn about Upper Occoquan Service Authority’s water recycling history & journey.
Upper Occoquan Service Authority (UOSA) is a regional water recycling facility that protects public health and the environment as trusted stewards of our most precious resource – water. They have a long track record and will discuss their story along with how they are facing new challenges, such as emerging contaminants (PFAS), changes to influent load from water conservation, and changes to treatment targets.
UOSA was formed on March 3, 1971 by concurrent resolution of the governing bodies of Fairfax and Prince William Counties and the Towns (now Cities) of Manassas and Manassas Park. UOSA’s product water flows via Bull Run to the Occoquan Reservoir, one of two major water supply sources for Virginia residents served by Fairfax Water. Fairfax Water serves nearly two million people in Fairfax County, the City of Alexandria, and portions of Prince William County and Loudoun County.
