Pretreatment Program

The City of Boise, and its citizens, love the Boise River. It enhances our quality of life, as a resource, a means of recreation, and a part of our culture. Since 1985, Boise City has regulated industrial and commercial wastewater discharges into the public sewer system through its EPA-approved Industrial Pretreatment Program. The Clean Water Act and the General Pretreatment Regulations (40 CFR Part 403) are the basis of this federal requirement.

The City of Boise’s public sewer system includes two wastewater treatment facilities and three contributing jurisdictions. The Pretreatment Program objectives are met by helping local businesses understand their responsibilities under the Boise City Code and the Federal Pretreatment Rules (pollution control requirements). Boise City's Pretreatment Program local legal authority is established by Title 8, Chapter 14 of the Boise City Code.

If you are an industrial or commercial business that discharges or plans to discharge wastewater to the Boise City sewer system, you should contact the Boise Pretreatment Program to determine which pretreatment requirements may apply to your wastewater discharge and if you need to apply for a permit.

As a resident of the City of Boise, there are also many things you can do to protect the City’s sewer system and, ultimately, the Boise River. Please see the Flushables and Residential FOG Program links for more information.
