Industrial User Survey

The City of Warrenton Public Works is conducting a survey of non-residential users connected to its sanitary sewer system to determine the presence of any industrial users discharging wastewater subject to pretreatment. The City of Warrenton Public Works rely on your answers to help achieve our commitment of providing a Municipality that meets the requirements of the Environmental Protection Agency’s mandated Industrial Pretreatment Program. A survey has been mailed out to metered commercial, and industrial sanitary sewer users that need to be filled out and returned back to the City of Warrenton: Public Works Department by November 1st 2022. 

This project is part of the Warrenton Industrial Pretreatment Program which is responsible for preventing harmful pollutants from entering its sanitary sewer system that could:

 • Impair the sewerage and treatment systems or its operations.

 • Pass through the sewer treatment plant and contaminate the Columbia River.

• Impair the quality of municipal digested sludge (biosolids) or reclaimed effluent.

If you have received a survey in the mail, and have any questions regarding the form or any part of this program, you can reach out to the City of Warrenton Public Works Department at:
