Project

As part of a long-term effort to reduce basement backups and sewer overflows, MSD Project Clear is designing a project to replace approximately 9,200 feet of wastewater sewer and 4,200 feet of stormwater sewer in the cities of Richmond Heights and Clayton, Missouri. MSD Project Clear will also disconnect sources where stormwater and groundwater enter the wastewater sewers (known as inflow and infiltration) from approximately 65 private properties.
