Industrial Pretreatment
Glenbard Wastewater Authority (GWA) is required by an EPA mandated program, The Clean Water Act (40 CFR 403) to regulate industrial and other non-domestic wastewater sources that discharge to GWA’s wastewater treatment system.

The purpose of the program is to:
- Protect the collection system and treatment plant infrastructure from physical damage from non-domestic pollutants.
- Protect treatment plant processes from harmful pollutants that could interfere with those processes.
- Protect the DuPage River from non-domestic pollutants that could pass through the plant untreated.
- Ensure that the GWA’s biosolids comply with land application requirements.
- Protect GWA employees from potentially harmful chemicals.
A permit to discharge may be required for industries in GWA’s service area discharging non-domestic wastes. New industrial and commercial facilities must submit an Industrial Wastewater Discharge Survey. For more information on discharge permits, local limits, and pretreatment forms, click a link below.
