Abstract: Article describing Rochester, New York's solution to its problem of combined sewage overflows (CSOs) that were discharged into the Genesee River, Irondequoit Bay, and Lake Ontario. The solution consists of 34 miles of large-diameter, deep-rock tunnels; an upgraded treatment facility; and improvements to the existing sewer system. Now, during a storm, CSO discharges are diverted to overflow relief sites where they drop into storage and conveyance tunnels averaging 150 feet below the surface. On its way to the treatment plant, the massive flow is directed so the capacity of the treatment plant is not overloaded.
