Combined sewers in older neighborhoods back up into basements during heavy rain. St. Louis's brick homes almost all have basements with floor drains connected to the sewer, which back up during heavy storms. The River des Peres, which carries both stormwater and sewage, overflows in heavy rain and floods nearby neighborhoods.

Brick homes with basements dominate, many with clay sewer laterals and floor drains connected to combined sewers. South City's brick homes and flats from the late 1800s to the 1930s have deep basements, original clay laterals and limestone or brick foundations that seep during heavy rain. Many are owner-occupied two-family flats, so leaks between floors are common.
