Illinois Drought

Aurora

System Information

System Description

Aurora receives water from an intake on the Fox River and 17 wells. The Fox River supplies 40-60% of the system's water depending on water quality conditions. The amount of groundwater used increases during occasional periods when algae in the river water causes taste and odor problems.

1989 Study:

50-year drought yield sufficient at present level of water use.

USGS Gages:

Fox River at Algonquin (05550000)

Developments since 1989:

A permanent ordinance for outdoor watering (odd- and even-day restrictions) was passed in 2006 to reduce summer demand. Continued population growth could raise average daily demand to 24.1 mgd and peak demand to 39.3 mgd in 2030. The system plans to add more wells to augment its supply.
