 Over 8,700 homes in Scott County rely on a septic system for their on-site wastewater treatment. A septic system is a large and important investment. It is vital that homeowners understand how their system works, and that they do what they can to extend the life of their Septic System. The positive benefits of a properly-functioning and long-lasting septic system are both financial and environmental.

Despite our abundance of lakes and rivers more than two-thirds of Minnesotans get their drinking water from ground water (i.e., wells).  Since septic systems discharge treated sewage into the ground, ultimately traveling to the ground water, they must be properly sited, designed, built and maintained to protect human health.

For information regarding the County's standards and criteria for Septic Systems, please review County Ordinance No. 4 (PDF)

On-site sewage system regulation is mandated by MN Rules Chapter 7080 (as recodified in 1990) and DNR rules Chapter 6120.3400 Subd. 3B., MN Chapter 145A.05, Metropolitan Council's Development Guide, and Scott County Ordinance No. 4 (See About Us / County Ordinances). The County's Ordinance is effective Countywide with coordination of enforcement and permitting in the larger cities.
