Highland Hills went on Lake Michigan thru the York TWP water system  at midnight on 6/5/18


Hydrant Flushing was conducted overnight and throughout the morning.


We will be leaving Hydrant Flushing signs out on the streets for next few days as needed, as we address any water quality issues.


We will be routinely  flushing dead ends and whenever  water quality complaints are called into 630-964-7503.

Please review our links for flushing your water lines as required during this supply change.

DuPage County's Water Division owns and operates six water systems within unincorporated areas including:

  • Southeast Regional Water System, in Darien
  • Greene Road/Hobson Valley Water System, in Woodridge
  • Steeple Run Water System, in Lisle
  • Glen Ellyn Heights Water System, in Glen Ellyn
  • North Regional Water Facility, in Itasca
  • York Township Water System, in Lombard

Together a combined population of about 13,000 people are served , distributing close to 400 million gallons of water a year through approximately 65 miles of pipe.  With the exception of the North Regional Water Facility, all systems distribute Lake Michigan water.

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.

For unincorporated DuPage County communities we may be able to assist you with providing a safe drinking water supply based upon your location, nearby water sources, raw water characteristics and the availability of capital funding. Please contact our Regulatory Manager to discuss the possibilities of setting up a Special Service Area at 630-407-6679.
