The North Regional Water Facility processes well water through a nanofiltration treatment system employing selective membrane based cross-flow filtration for the removal of contaminants responsible for water hardness and discoloration. Customers receive
a purified water with a hardness value of three to five grains per gallon.
All County Water Division systems comply with Illinois Environmental Protection Agency (IEPA) regulatory policies including regular bacteriological and contaminant testing of standby wells and distribution points in accordance with IEPA guidelines.
It is the goal of the DuPage County Water Division to constantly improve customer water quality and service. If you have questions, concerns or would like further information about any of our water systems, please contact us at 630-964-7503.

Cross-Connection Control Program
To protect the integrity of our drinking water supply and for your health and safety, a Cross-Connection Control Program (CCCP) is included in the DuPage County Water Supply, Distribution and Wastewater Treatment Ordinance and provides
- Authority to require certain backflow prevention devices within any residential or commercial property that is connected to the County water supply;
- Promotion of compliance with public water supply safety regulations in the Federal Safe Drinking Water Act, the Illinois Environmental Protection Agency’s Regulation Title 35, and the Illinois Plumbing Code, and;
- Protection of the public drinking water supply from backflow contamination through cross-connections.
A cross-connection is any piping arrangement (actual or potential) between the drinking water supply and any other water source, which under certain conditions, may result in backflow contamination into the drinking water supply. Examples of cross-connection
hazards include underground sprinkler irrigation systems, fire protection systems, pools and hot tubs, and industrial ice machines, among others.
The Illinois Environmental Protection Agency (IEPA) requires that we conduct a biannual All Drinking Water System Connection Survey. This survey is an integral part of the program, in which we rely on our water customers to provide accurate information
regarding the hazards present at the property. As a result, a survey has been prepared to assess risk and compile backflow prevention device data for properties serviced by DuPage County Public Works. Customers have the choice of filling out the electronic
survey (E-Survey) or filling out the PDF and submitting the survey to our department manually. This program is intended to protect all drinking water customers, and your active participation is required.
If you have any questions, or require additional information, please contact the CCCP manager directly at (630) 407-6808.
