Industrial Pretreatment
Bensenville’s Wastewater Treatment Plant operates under a permit issued by the Illinois Environmental Protection Agency. The treatment of municipal wastewater is regulated by the Clean Water Act and the provisions of the National Pretreatment Program.
Industrial Pretreatment
Bensenville’s Industrial Pretreatment Program is a mandated program through the U.S. Environmental Protection Agency (USEPA). The Clean Water Act (40 CFR 403) regulates industrial and other non-domestic wastewater sources that discharge to the wastewater treatment plant.
The purpose of the Industrial Pretreatment 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 Addison Creek from non-domestic pollutants that could pass through the plant untreated.
- Ensure that the wastewater treatment plant’s biosolids comply with land application requirements.
- Protect employees from potentially harmful chemicals.
A wastewater discharge permit may be required for industries to discharge to Bensenville’s wastewater treatment plant. A wastewater user survey is required for new businesses that are discharging wastewater to the treatment plant.
How do I know if my business will be included in the pretreatment program?
Industrial Users are regulated by their Federal Categorical Pretreatment standards and by Bensenville’s Sewers and Wastewater Treatment Ordinance. To determine what Categorical Pretreatment Regulations or Surcharge limits might apply to your business, contact the Pretreatment Coordinator in the Public Works Department at 630-350-3435.
What is a Wastewater User Survey?
The Wastewater User Survey is a requirement of Bensenville’s industrial pretreatment program through USEPA. Collecting information on businesses and the wastewater discharged from their facilities helps Bensenville to include applicable businesses in the program and better protect the environment. This survey is mandated by USEPA Federal Regulation 40 CFR 403.8 (f)(2(i).
If you have received a Wastewater User Survey, your business is within a commercial or industrial zoned area that discharges to Bensenville’s wastewater treatment plant. The list was developed based on water usage records, manufacturing and service directories, and business license documentation. Please take a few minutes to complete the survey at tinyurl.com/bensenvillewastewater using the User ID provided in the letter.
Questions regarding the survey should be directed to the Pretreatment Coordinator at 630-350-3435. All recipients of this letter who do not return the survey by the deadline will be subject to an unscheduled on-site interview or inspection to obtain the survey information, per Village Ordinance Section 8-6-4-1.
