Our Industrial Pretreatment Program controls the release of toxic substances into the wastewater system by monitoring the discharge of significant industrial users (SIU).
All non-domestic users in the Grand Rapids Water System complete a survey to collect detailed information on their use. Facilities deemed SIUs must then apply for a permit to specify discharge standards and conditions.
Send permit applications via mail or fax to 616-456-4423.
