With the underground water aquifer drying up, not even a deeper search or conservation methods will help the village of Oswego with possible implications for Yorkville and Montgomery which are joining forces for an alternative source.
Oswego Public Works Director Jennifer Hughes provided this information at Tuesday’s Oswego Village Board meeting.
Currently Lake Michigan with three options or the Fox River are the main future sources being considered. Oswego could be on Lake Michigan water from the DuPage Water Commission from a stub near southwest Naperville by 2025. Joining the Joliet draw of Lake Michigan could be ready by 2030.
A layer of shale rock is blocking rainwater from reaching the aquifer, which is like an underground storage tank. In addition, the demand for water has exceeded the recharge of the aquifer for over 100 years.
According to the Illinois State Water Survey or ISWS, seven of eight Oswego wells are in the range of decreasing ability to reach water and the risk of well interoperability.
Cecilia Cullen, of the ISWS, said there could be another problem looming.
By 2050, the population of Oswego is projected at 54,000 and over 143,000 residents for Yorkville, Montgomery, and Oswego combined. Currently, well capacity timelines are under review by Montgomery and Yorkville.
By 2025, a new well will be required for Oswego costing between $7-10 million and taking three years to plan and construct.
Going deeper with current wells can cost dollars for the process, bigger pumps, new motors, and equipment at an estimated half-million dollars per well.
Elgin and Aurora use the Fox River as a source, but there are concerns about low river levels, stormwater and wastewater entering the river upstream. A new regional surface water plant would be required.
But an expected decision from Oswego would be coming in December for joining the proposed Joliet pipeline off Lake Michigan. More than 6.6 million people in the Chicagoland region receive Lake Michigan water.
