Industrial Pretreatment

The industrial pretreatment program protects the city’s wastewater collection and treatment systems and the environment by preventing toxic and dangerous substances from discharging into the sanitary sewer system.

We work with businesses to ensure the sewer system remains free from toxic and dangerous substances, by:

  • Issuing Discharge Permits
  • Performing Site Inspections
  • Monitoring Discharges
  • Enforcing Pretreatment Standards and Requirements
     
Business Owner Responsibilities
Wastewater Questionnaires
As a business owner within the city, you may be required to fill out a wastewater questionnaire either at the time of business startup or at a later date.  This is the simplest way for the city to initially assess the nature of your wastewater. An additional questionnaire or inspection may be required based on the information provided.


Pretreatment Inspections
Some business practices are expected to be subject to the pretreatment program (metal finishers, dairies, chemical facilities, etc.).  In these cases, inspection of your premises will be forthcoming.  A wastewater questionnaire may trigger an on-site inspection.  The purpose of the inspection is to assess the quality, strength, and quantity of wastewater that your business generates.

Pretreatment Permits
If conditions warrant, the city may issue your business a discharge permit.  This permit will serve as a framework under which your business may discharge wastewater to the city's Wastewater Treatment Plant.

Certain “one time” disposal practices may warrant the issuance of temporary permits.  Please contact us if you would like to conduct a non-routine disposal procedure that you think may cause problems to the city's publicly-owned treatment works or may not be allowed under local code or national pretreatment standards.
