Water Rates

Notice of Water Rate Increase

On November 10, 2015 the Village Board approved a 10% increase in water rates and  $2.67 per month, or 36% increase in the fixed service charge based on the recommendation of the Water Rate Study Report.   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.

The Village’s Water Fund is projected to decline in year 2017/2018 where maintenance and replacement projects are being deferred due to lack of funding. The purpose of the Water Fund is to ensure that the water supply and distribution system will have the capacity to serve its residents without taking on any debt.

The new rates would go into effect January 1, 2018 and be reflected in water bills issued on March 1, 2018 for residents and non-residents.  For corporate customers, the new rate will be reflected in water bills issued on February 1, 2018.

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 substantial increases in water rates, it is important to continue implementation of the 2015 Water Rate Study recommendations to ensure the on-going viability of Oak Brook's water system.
