Owning a lake home in Mille Lacs County means enjoying one of Minnesota’s most popular waterfront regions. From Mille Lacs Lake to smaller lakes and rivers throughout the county, many homes rely on private septic systems rather than municipal sewer service. For these properties, wastewater is treated through a Subsurface Sewage Treatment System (SSTS) commonly called a septic system. These systems safely treat wastewater from homes and cabins while protecting the lakes and groundwater that make Mille Lacs County such a desirable place to own waterfront property. Many Mille Lacs County lake homes fall within designated shoreland areas, which are lands located near lakes and rivers. Because of their proximity to water, septic systems in shoreland areas must follow stricter guidelines designed to protect water quality, such as: required setback distances from lakes, rivers, and wells, properly designed drainfields or mound systems, soil treatment areas sized for the home, professional design and inspection and upgrades when systems become non-compliant. Lake homes with compliant septic systems are easier to sell and finance. Buyers and lenders often want confirmation that the septic system meets local standards.
