About Lake St. Louis, Missouri (63367)

Lake St. Louis is a fast-growing, family-friendly city in western St. Charles County with a population of over 17,000 residents (as of 2025). Located just 40 minutes west of downtown St. Louis along Highway 40/64, the city is known for its two private lakes, top-rated schools in the Wentzville School District, beautiful parks, and thriving local businesses. Many homes and new developments in Lake St. Louis and nearby towns like O’Fallon, Wentzville, Dardenne Prairie, and Foristell rely on septic systems rather than municipal sewer – making professional septic installation and maintenance essential.
