About Saint Clair, Missouri

Saint Clair is a growing city in eastern Franklin County with a population of approximately 4,800 residents (2023 estimates). Located just 55 miles southwest of St. Louis along Interstate 44, Saint Clair offers small-town charm with easy access to metropolitan amenities. The city has seen steady growth as families and businesses move from the St. Louis metro area seeking affordable land and a quieter pace of life – which often means new homes and businesses needing properly designed septic systems instead of city sewer.

Because much of Saint Clair and the surrounding 63077 area sits on clay-heavy soils with seasonal high water tables, choosing an experienced local installer is critical to avoiding costly failures down the road.
