It is critical that UOSA knows what is being discharged into UOSA’s treatment plant from industrial and commercial activities to have an effective pretreatment program.
To gather this information, UOSA relies on Industrial User Surveys (IUS). IUSs are forms used to identify and gather information about industrial and commercial dischargers that may flow to UOSA’s sewer collection system. The UOSA sewer collection system (or Sewershed) serves the northern half of Prince William County, a western portion of Fairfax County, and the entirety of the Cities of Manassas and Manassas Park. Links to Fairfax County’s, Prince William County’s, City of Manassas’s, and City of Manassas Park’s respective Sewer Ordinances can be found in the tab to the right under “Ordinances.”
Identifying industrial and commercial discharges is required by federal and 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 industrial or commercial facility to fill out an Industrial User Survey.
You can find the Industrial User Survey pdf by clicking on the tab to the right labelled “Industrial User Survey.”
The form can be completed using the fillable pdf form and emailed 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.”
