Commercial & Residential Septic Services in Rochester, MN

When you purchase a new home or commercial property, one of the costliest parts of your investment is the septic system. It’s certainly not the most glamorous part of your residential or commercial property, but it’s one of the most critical! Without a properly functioning septic system, you can encounter some serious and costly problems.

DeCook can take care of all of your septic system needs, from installation to repair. We'll install your septic system right the first time, taking into consideration elements such as ensuring your septic system is matched for proper grading, design, and making sure we meet soil compliance. We offer septic tank installation and services in Rochester, MN, and surrounding areas. We’re licensed, bonded, and insured to do both residential and commercial septic work, including septic tank repairs.

To ensure a professional installation of your residential or commercial septic system, we take the following steps:

  • Complete a comprehensive septic site survey
  • Perform a pre-dig inspection
  • Soil testing
  • Determine the appropriate type of septic system based on the information we gather

Professional Septic System Installation You Can Trust

We start with a site survey which helps us determine the space available for the septic system. A pre-dig inspection helps us find out if there are any existing wells or septic tanks that need to be removed, and if there are, we secure the required permits and safely remove them.

A soil sample is then taken (called boring), and this is one of the most critical parts of helping us understand the structure of the soil and its capacity to drain. After wastewater is separated from solids in a septic tank, it flows out into a drainfield (sometimes called a leach field) where the liquid is absorbed into the earth. Making sure the soil can absorb this waste is essential to prevent overflow which can negatively affect the environment.
