MSD Project Clear Update – May 13, 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 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 the contractor will excavate to the top of the rock surface for installation of the approach channel. They will then begin drilling the existing rock surface to make it easier to excavate and then use a hydraulic breaker to excavate the rock.    
          • 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 continue constructing the approach channel that connects the Diversion Structure to the pipes that drop flow into the tunnel.
