||The report discusses feasibility studies for the initial stage (Calumet Area) of the Deep Tunnel Plan for flood and pollution control in the Chicagoland Area. Basically, the Plan would utilize existing lateral and main sewers, with additional main sewers to relieve laterals at their high ends. Both the existing and new main sewers would be intercepted at appropriate locations by vertical shafts connecting to a tunnel system 600 feet or more below the ground surface. These tunnels, or galleries, would both temporarily store storm water overflows and drain these waters to a reversible pump-turbine plant location near the Calument Sewage Treatment Works.
