Metropolitan Sewer District Headquarters

Much of Saint Louis city is located within the combined sewer overflow (CSO) area, meaning that stormwater from the street is mixed with sanitary sewage. During large rain events, the system becomes overwhelmed, resulting in raw sewage being discharged into the Mississippi River. In 2011, Metropolitan Sewer District (MSD) entered a Consent Decree and will spend a minimum $4.7 billion over the next 23 years to address the issue of overflows and other sewer system improvements.

DTLS is currently in the process of conceptual design and visioning for potential improvements to the MSD headquarters at 2350 Market Street.  The proposed campus upgrades are targeted at showcasing MSD’s mission of reducing negative stormwater impacts, while supporting public education and enhancing accessibility.

We will achieve this goal by constructing a diverse stormwater management and landscape design plan that demonstrates the full variety of best management practices. These green infrastructure improvements will be part of a campus educational loop that is centered around an architectural pavilion for outdoor educational sessions and employee seating.
