Engineer I/II

Upper Occoquan Service Authority

About the organization

The Upper Occoquan Service Authority (UOSA) is a state-of-the-art water reclamation plant located in Centreville, VA. UOSA was created in 1971 to transform the Occoquan Watershed from a largely rural area to a predominantly urban/suburban region mandated by the Occoquan Policy.
In 1978, the UOSA Regional Water Reclamation Plant, commenced operations and replaced eleven small secondary treatment plants in the region. Since that time, water quality in the Occoquan Reservoir has steadily improved and the reliable, high-quality effluent produced by UOSA has increased the safe yield of the Reservoir.

UOSA’s product water flows by way of Bull Run to the Occoquan Reservoir, a major water supply source for over 1.3 million people within the areas, which include Prince William County, Fairfax City, City of Manassas and Manassas Park. We pump 54 million gallons of water per day and sit on 455 acres.
