Industrial Wastewater

The City is mandated to implement an Industrial Waste Program in order to reduce the amount of harmful pollutants discharged into the City sewer. The intent of the program is to:

  • To enable the City to comply with the National Pollutant Discharge Elimination System Permit.
  • Helps the City to produce quality effluent for reuse and recycling.
  • Protect the public, the environment, and City wastewater staff and facilities from harmful industrial discharges.


The program does this through the permitting of facilities with certain types of industrial discharges. The legal authority to implement the program can be found in Chapter 14.10, Sewer Use, of the City's Municipal Code. The programs included under Industrial Wastewater are:

  1. Industrial Waste Program
  2. Fats, Oils & Grease Program
  3. Small Winery & Small Brewery
  4. Hauled Waste - Dump Stations

Industrial Wastewater Discharge Permits are issued to facilities which fall under the requirements of Title 40, Code of Federal Regulations (CFR), Part 403 or discharge pollutants that may be harmful to the wastewater system. Permitted facilities may be required to monitor their discharge to ensure compliance with the local discharge limits listed in Section 14.10.070(B) of Sewer Use Ordinance.

Industrial Wastewater Survey 

New industrial facilities are required to complete and submit an Industrial Wastewater Survey to the Industrial Waste Manager. If it is determined that additional information is needed, an inspection and /or an Industrial Waste Discharge Application may be required to determine if a permit should be issued.
