Aerators stop odors in Chicago
Article Abstract:
Stormwater runoff into the combined sewer network which serves Chicago, IL, and its surrounding 51 communities frequently exceeded network capacity. As a result, excess rainwater flows mixed with raw sewage would cause flooding and severe pollution of the waterways in the metropolis. City officials therefore opted to construct four tunnel systems and three reservoirs. The Chicago Underflow Plan O'Hare Reservoir is the first of the three reservoirs to be completed. Its nine surface aspirating aerators have prevented wastewater odors while keeping wastewater from becoming septic.
