Sanitary Storage Tunnel & Tank Projects

Client: Various Engineering Firms
Owner: Metropolitan St. Louis Sewer District
Year: Ongoing

MSD Project Clear is a $6 Billion, 28-year-long initiative to improve water quality and reduce SSOs and CSOs throughout the District. To prevent overflows, MSD is building both above-ground storage tanks and deep underground tunnels to both store and transport wastewater during heavy rain events until treatment facilities can handle the volume.

M3 teamed with prominent engineering firms to calibrate watershed models, provide alternatives analyses, and pre-design in order to complete design plans for the District on the following sanitary Tunnel and Storage Tank Projects.
