About Saint Mary, Missouri (Population ~350)

Nestled along the Mississippi River just 12 miles south of Ste. Genevieve, the historic village of Saint Mary, MO is one of Missouri’s oldest communities. Founded in 1799, this quiet river town offers small-town charm with easy access to larger cities like Festus, Farmington, and Perryville. With a population of around 350 residents, Saint Mary is known for its beautiful bluffs, rich Catholic heritage, and peaceful rural lifestyle – making properly functioning septic systems absolutely essential for homes and businesses here.

Because much of the area is not connected to municipal sewer systems, a dependable septic system is critical to protecting both your property and the local groundwater that feeds into the Mississippi River.
