Stormwater Management to Host Elmhurst Quarry Tours on Sept. 30

In partnership with the Elmhurst History Museum, DuPage County Stormwater Management will offer a rare opportunity to take a public tour of its Elmhurst Quarry Flood Control Facility on Saturday, September 30. 

Stormwater Management Committee Chairman Jim Zay said DuPage County residents will have the opportunity to tour the Quarry to learn how the County uses it to manage floodwater, along with its history in the community. 

“The Elmhurst Quarry holds 2.7 billion gallons of stormwater and is by far the largest flood control facility of our 16 pump stations and reservoirs. However, not only is it one of our most important flood control facilities, it also has the most interesting history,” said Zay. “Because of its unique presence in the County, residents are always interested in visiting it, and this tour allows us to accommodate a large number of visitors.”

The Elmhurst Quarry is the largest of five mechanically operated flood control facilities in DuPage County. Using a predetermined operating plan, DuPage County Stormwater Management staff allows floodwater to enter the Elmhurst Quarry via a 400-foot tunnel, which runs under Illinois Route 83. The Quarry holds the floodwater until water elevations recede enough to pump the water back into Salt Creek. 

Tours will depart from the Elmhurst History Museum, located at 120 E. Park Avenue in Elmhurst, via bus every 30 minutes from 9 a.m. to 2:30 p.m. Each tour will last approximately 2 hours. Cost for the tour is $10 per person, payable to the Elmhurst History Museum. 

Following the quarry visit, participants can take a self-guided tour of the Elmhurst History Museum’s exhibit “By All Accounts: The Story of Elmhurst,” which includes more information about the quarry’s history. 

Quarry tour ticket sales will begin at 9 a.m. on Wednesday, September 6. Tickets can purchased online on the Elmhurst History Museum’s website at in the Special Events section. Children 10 and over are allowed, but must be accompanied by an adult. For more information, call the Elmhurst History Museum at (630) 833-1457.
