Welcome to UOSA’s Pretreatment Program information page
UOSA’s pretreatment program aims to be at the forefront for achieving UOSA’s goals in protecting public health, the environment, and UOSA by researching, capturing, evaluating, and where necessary, regulating industrial and commercial wastewater flow, at the source. This program also ensures UOSA is adhering to public interests and meeting and exceeding all State and Federal regulations.
Part of this process is the use of Industrial User Surveys. Industrial User Surveys are forms used to identify and gather information about industrial and commercial dischargers that may be flowing into UOSA’s sewer collection systems. UOSA’s collection system serves select areas in the Counties of Prince William and Fairfax and the cities of Manassas, and Manassas Park. Links to Prince William’s, City of Manassas, and City of Manassas Park’s respective Sewer Ordinances can be found in the tab to the right under “Ordinances.”
Identifying industrial and commercial users of a sewer system by an entity like UOSA is required by federal and VA state law. As such, if you have been brought to this page by a QR code, link, search, or other means, it is likely UOSA has requested your business or commercial facility or industry to fill out an Industrial User Survey.
You can find the pdf link to the Industrial User Survey on the tab to the right, under “Industrial User Survey.”
The form can be completed using the fillable pdf form and emailing it to RegulatoryAffairs@uosa.org. You can also print, complete, sign, scan, and email the form to RegulatoryAffairs@uosa.org. Alternatively, you can mail the completed form to UOSA using the information under “Mailing Address.”
For questions, comments, and contact information, refer to the “Contact Us” tab on the right side. This information can be used to submit any Industrial User Surveys directly to UOSA, as well.
