Septic and drainfields
Domestic Wastewater
Most homes in shoreland and rural areas rely on Subsurface Sewage Treatment Systems (SSTS), commonly known as the septic system. Your septic system, if designed, installed, and maintained properly, will effectively treat wastewater before it is returned to the environment to protect public health and prevent pollution of a nearby lake or river.

What Causes a Septic System to Fail?
Septic system failure is most commonly the result of:
• Improper maintenance;
• Overuse of water in the home; and/or
• Improper design or installation of the system.
​
When your system, or a neighbor’s system fails, untreated wastewater could come in contact with people, causing a public health hazard, or enter the groundwater and eventually the lake, adding pollution that can contribute to increased algae and plant growth.
If You Have A Problem:
• Contact Cass County Environmental Services for advice and/or
check their website for a list of licensed septic inspectors.
• If the drain field or household pipes are not clogged, have the system pumped for both solids and liquids as a temporary measure.
• If there is surface pooling of wastewater, fence off the area to prevent contact with humans or pets.
Low Interest Septic Loans Available
Low interest loans are available to Cass County Homeowners to repair or upgrade an existing septic system. 5 year loans, at a rate of 3%, are available for qualified property owners in Cass County. The goal of the program is to improve the environment by replacing non-compliant systems. For more information refer to the Cass County Environmental Services website.


Pump the Tank Regularly
Have a licensed professional pump the solids (floating
scum and sludge) that have accumulated from the
septic tank every one to three years—the more use, the
more often pumping is needed. Make sure they pump
through the manhole.
