The Deer Creek Tunnel is a key element of the Metropolitan St. Louis Sewer District’s (MSD) “Project Clear” initiative to eliminate sewer overflows during heavy storms due to the limits of older wastewater collection and treatment systems. This half-mile long, 28-feet wide tunnel lies 175 feet below St. Louis’ riverfront. During a period of extreme precipitation, the tunnel fills up, then a pump station moves the stored contents to the Bissell Point Wastewater Treatment Plant before being discharged into the Mississippi River.
Penetron’s antimicrobial admixture was used to treat over 17,050 yds3 of concrete used to line the Deer Creek Tunnel.
