Industrial Waste Survey (IWS)

Industrial Waste Survey (IWS)

The City of Sioux Falls is required by EPA 40 CFR 403.8 (f)(2) to identify and locate any industrial and commercial facility that may impact the Publicly Owned Treatment Works (POTW).

In support of this requirement, the Public Works Environmental Division uses an Industrial Waste Survey (IWS) to evaluate the potential for facilities within our service area to impact the POTW.

Information collected by the IWS is used in the determination if any industrial or commercial wastewater at the facility could:

  • interfere with daily POTW operations 
  • limit the usefulness of biosolids 
  • endanger the health or safety of wastewater collection system workers 
  • pass through the POTW’s treatment process, ultimately harming human health and/or the environment.

If your facility has received a survey, please complete it to the best of your ability. You may print or download a copy of the IWS survey forms below. For questions related to the IWS call the Environmental Division at 605-367-8276.
