The DNR standards are primarily a prescriptive code giving design criteria for each alternative type of secondary treatment system permitted.
Counties have the authority to allow alternative or innovative performance based systems.
They’re most common in rural areas, where public sewer access is not readily available.
Several types of septic systems are used across the country, but the most common is the septic tank/absorption field system.
The rules and regulations for a private system are outlined in Iowa Administrative Code, Chapter 69.
Septic systems are usually a permanent solution to wastewater treatment and disposal.Therefore, they must be properly used, operated, and maintained by the homeowner to assure the long-term performance of these systems.Even when used as a temporary wastewater treatment solution until sewer lines are extended to a community, special care and maintenance are needed for septic systems so that they don’t pose a risk to public health or the environment.Please note that Stearns County has recently upgraded its website to be responsive.As such, we cannot best support older browsers, such as Internet Explorer 8 and below.The DNR also licenses all commercial pumpers of septic tanks.
