[ARCHIVED] MSD Project Clear Update – April 29, 2021

MSD Project Clear Update

Work anticipated in the next three weeks on Metropolitan St. Louis Sewer District’s Project Clear in Brentwood:

        • Deer Creek Sanitary Tunnel – The contractor will continue construction of the deaeration chamber at the site at the corner of Brazeau and Suburban Tracks. This structure is located underground at the tunnel elevation, but the workers, equipment, and materials used to construct the structure will be lowered into the tunnel from a crane at the surface. Within the next three weeks, the contractor will continue installing the riser pipes from the deaeration chamber until they reach the elevation of the approach channel, which is closer to the surface. Near the end of the three-week period they may begin drilling the existing rock surface to make it easier to excavate for the approach channel.  
        • Deer Creek Sanitary Tunnel – The contractor continues construction of the Diversion Structure within the sheet pile excavation support system previously installed at the site located near Manchester and Breckenridge Industrial. The contractor will complete installation of the riser pipes from the deaeration chamber and the tunnel shaft will be filled outside of the riser pipes. They will begin constructing the approach channel that connects the Diversion Structure to the pipes that drop flow into the tunnel.
