Protecting our water starts with well‑designed and well‑maintained septic systems. One‑third of Minnesotans rely on these systems—also known as subsurface sewage treatment systems (SSTS)—to safely treat their wastewater. By using the natural filtering power of soil, septic systems remove pathogens and other contaminants so treated water can safely re‑enter the water cycle.
Septic systems aren’t one‑size‑fits‑all. From simple gravity trenches to more complex mound systems, designing the right system for a property requires careful evaluation and planning.
