Industrial Pretreatment

The Industrial Pretreatment division is responsible for the control of pollutants from non- residential users of the City’s Sanitary Sewer System. Its intent is to protect the City’s sanitary sewer collection system, wastewater treatment facility, employees who maintain these systems, the environment, and to meet Federal, State and Local Regulations.

All businesses within the City of Kalispell’s and Evergreen’s service areas are required to meet the requirements of the City’s Industrial Pretreatment Program.
