Water Rates


Notice of Water Rate Increase

On November 10, 2015, the Village Board was presented a 5 year Water Rate Study that recommended annual increases of 10%, 10%, 7%, 7%, and 7% beginning in 2016. A copy of the Water Rate Study Report can be found here.  It cites three main reasons causing the need for the increase:
   

1.   There were significant increases by DuPage Water Commission and City of Chicago over the past 4 years.  In 2012, Chicago increased its rate for 4 years of 25%, 15%, 15%, and 15%.  Then DuPage Water Commission added an additional increase on top of that resulting in increases of 30%, 20%, 18%, and 17%.  The Village did not raise its rates high enough to keep up with these increases.

2.    There was a substantial increase in the non-revenue water in the last 5 years.  Non-Revenue water is referred to as loss and unaccounted for water.  Public Works will be working with our consultant to reduce this amount to obtain substantial savings.                            

  1.  The water system infrastructure is agingLarge portions of the system have reached their useful life.   A significant investment  is   needed  to avoid disruptions in water service due to failed equipment.
 

During 2018, the Village updated the original Water Rate Study.  The updated 2018 Water Rate Study Report can be found here.  The updated report provided the Village with multiple options to set rates for 2019-2023.  The Village Board adopted a 5% rate increase effective January 1, 2019 based on the results of this report. 

The new rates would go into effect January 1, 2019 and be reflected in water bills issued on March 1, 2019 for residents and non-residents.  For corporate customers, the new rate will be reflected in water bills issued on February 1, 2019.

Even after the water rate adjustments are made, water bills in Oak Brook will remain competitive when compared to the average DuPage County Municipalities.

Despite the increases in water rates, it is important to continue implementation of the 2018 Water Rate Study recommendations to ensure the on-going viability of Oak Brook's water system.
