Dec. 2, 2021
Combined sewer overflows challenged capacity in Joliet, Illinois, so the city built a storm tunnel under the highway and Des Plaines River.

As Joliet, Illinois, battles a water scarcity issue for drinking water, it was also battling an abundance of stormwater stressing facility capacity. The Joliet Combined Sewer Overflow Tunnel and Wet Weather Treatment Facility aimed to make this issue a matter for the past.
