A Flooded Tunnel Interceptor System for the Metropolitan St. Louis Sewer District

Abstract

Preliminary studies showed that a flooded tunnel interceptor system would be the most advantageous type for an area of St. Louis, Mo. Interceptors were designed to carry ultimate peak dry-weather flows only, since the city has many combined sewers. The interceptors will exclude backwater from the Mississippi River at low to moderately high river stages. A boring machine was used for parts of the tunneling during construction. Operation of the system will depend on river stage, rainfall, and the operation of an interconnected floor protection system. Drawdown of the wet well at the terminal pumping station will be necessary periodically to promote cleansing of the tunnels. The system is furnished with telemetering devices and central controls.
