Setting the Standard in Septic Systems in Southern Minnesota

Our Septic treatment systems are designed to meet the needs of your home or commercial site. Residential systems are based on the number of bedrooms in the home and commercial systems are based on the number of employees. Every building site is unique.  

To determine the type and size of a septic system; Seppmann & Sons will evaluate the soils and site to determine how to best meet your site specifications.

The basic septic treatment systems are an in-ground gravity septic system, a mound or pressure distribution system, or advanced systems including aerobic treatment. An in-ground gravity system works by allowing gravity drain the effluent waste from the septic tank into trenches installed under the surface. This requires that the septic system treatment area be below the outlet pipe in the septic tank. 

A mound or pressure distribution system includes a lift station with a pump. The effluent waste water is pumped through a pipe to the septic treatment area. This system is installed to meet soil separation requirements.

Advanced treatment systems including aerobic treatment systems come in a wide variety of options. Special treatment systems are used when shallow soils exist on the site or space limitations do not allow for a standard in-ground or mound system. 

Seppmann & Sons will work with you to design and install the best solution for your site. 


Customer Review:

“We live in the Minnesota river valley near Henderson on a "very challenging" site (as we were told by several contractors). I was given Jadd Seppmann & Sons name from a coworker who recently had work done by them and was very happy.
Drew Seppmann came out, surveyed our lot and designed a septic system that fit our property and was not crazy expensive like the quote we got from a system designer based in Le Sueur.
Drew and his crew worked fast, left the site clean between visits and did an excellent job on the final grade of the site upon completion. I felt like Drew went above and beyond to help us get our septic system replaced. Peggy also provided great guidance throughout the process and was very communicative every step of the way.
I've come to believe this family-owned business does indeed go above and beyond customers expectations as their normal standard of service. I highly recommend Jadd Seppmann & Sons and wish to publicly thank them for everything they did for us.”
