The Oak Park outlet sewer in Chicago Avenue was built by tunnel. Miners on December 13, 1921, used the only method available, manual labor, to excavate the tunnel. Timber sheathing and posts supported the soil. Screw jacks were used to force timbers into place and for additional support. The outlet sewer initially discharged to the Des Plaines River at Chicago Avenue. (MWRD photo 8702)
