Our Installation Process

A new septic system is a big investment, and you deserve to know exactly what happens at each stage. Here is how we approach every installation in the Columbia area.

  1. Site Evaluation Every installation starts with a thorough look at your property. We assess the lot size, slope, soil composition, and proximity to wells, waterways, and property lines. This tells us what type of system will work best and where it should go. In Boone County, soil conditions can vary significantly even within the same neighborhood, so this step is essential.
  2. System Design Based on the site evaluation and soil percolation test results, we design a system tailored to your property and household size. We factor in bedrooms, anticipated water usage, and future needs. Whether you need a conventional gravity system or something more specialized, the design is engineered to meet Missouri Department of Health regulations.
  3. Permitting Boone County requires permits for all new septic installations, and we handle the paperwork for you. We submit the system design, soil test results, and site plans to the county health department. Permit approval typically takes two to four weeks, and we keep you informed throughout.
  4. Excavation Once permits are approved, our crew brings in equipment to excavate the tank pit and drain field trenches. We use designated access paths and tarps to protect your lawn. The size and depth of the excavation depend on your system design and local soil conditions.
  5. Tank & Pipe Installation The septic tank is carefully set in place, leveled, and connected to your home's plumbing via inlet piping. We use heavy-duty concrete or poly tanks rated for residential use. All connections are sealed and tested before we move on to the next phase.
  6. Drain Field Construction The drain field (also called a leach field) is where treated wastewater disperses into the soil. We install distribution pipes, gravel beds or chamber units, and filter fabric according to the engineered design. Proper drain field construction is what makes the difference between a system that lasts 25 years and one that fails early.
  7. Backfill & Grading After everything is installed and connected, we backfill the excavated areas with clean fill dirt. We grade the surface to ensure proper drainage away from the tank and components. Your yard is prepared for seeding or sodding so it can recover quickly.
  8. Final Inspection Before we consider the job complete, a Boone County inspector visits the site to verify the installation meets all code requirements. We schedule this inspection and are on-site to answer any questions. Once it passes, we walk you through your new system and provide maintenance guidelines to keep it running smoothly for decades.

Types of Septic Systems We Install

Not every property in the Columbia area can support the same type of septic system. Soil conditions, lot size, slope, and water table depth all play a role. We install four main types and will recommend the right fit for your situation.

Conventional Gravity Systems

The most common type of residential septic system in Boone County. Wastewater flows by gravity from the tank to a drain field made of gravel-filled trenches. These systems work well on properties with adequate soil drainage and enough space for the leach field. They are reliable, low-maintenance, and have a long track record.

Aerobic Treatment Systems

Aerobic systems use oxygen to break down waste more efficiently than conventional designs. They produce cleaner effluent, which means they can work on properties with tighter soils or smaller lots where a traditional drain field would not be practical. These systems include a mechanical component that requires periodic maintenance, but they open up options on challenging sites.

Mound Systems

When the water table is too high or bedrock is too close to the surface, a mound system raises the drain field above the natural grade. A pump moves effluent from the tank up into a constructed sand mound where treatment occurs before the water reaches the soil below. Mound systems are common in parts of mid-Missouri where terrain and groundwater make standard installations impractical.

Chamber Systems

Chamber systems replace traditional gravel drain fields with lightweight plastic chambers that create void space for effluent distribution. They are easier to install (especially in areas where gravel is expensive to haul in), and they perform well in a variety of soil types. Many homeowners around Columbia choose chamber systems for their durability and simpler maintenance.

Septic Installation FAQs

Common questions from homeowners in the Columbia area who are getting a new septic system.

A full septic installation begins with a site evaluation and soil testing, followed by system design, permitting through Boone County, excavation, tank and pipe installation, drain field construction, backfill and grading, and a final county inspection. We manage every step so you do not have to coordinate between different contractors or agencies.

Each installation is different depending on your property's soil, slope, and size. Call us at (573) 488-5277 to discuss your specific situation.

Most residential septic installations in the Columbia, MO area take between 3 to 7 days of on-site work, depending on the system type and soil conditions. Before work begins, the permitting process with Boone County typically adds 2 to 4 weeks. We keep you updated at every stage so there are no surprises.

If you are on a tight timeline — for example, building a new home — get in touch early so we can start the permitting process while other construction is underway.

Yes. Boone County and the Missouri Department of Health and Senior Services require permits for all new septic system installations. The permit process includes submitting a soil percolation test, a site plan, and an engineered system design for review.

We handle all of the permitting paperwork for you. It is included as part of every installation project — you will not need to visit county offices or figure out the requirements on your own.

During installation, you will see heavy equipment (excavators and trucks) on your property. We use designated paths and tarps to protect as much of your yard as possible. There will be noise during working hours, and a portion of your yard will be excavated and temporarily disrupted.

Our crew communicates daily about progress and what is happening next. If you have concerns about access, landscaping, or scheduling, we address those before work begins. Call or text (573) 488-5277 with any questions.

Yes. After installation, we backfill all excavated areas, grade the soil for proper drainage, and prepare the surface for seeding or sodding. We clean up debris, remove equipment tracks, and leave the site as close to its original condition as possible.

Most yards recover fully within one growing season. We take pride in leaving properties looking better than we found them — your neighbors should not be able to tell where the work was done once the grass fills in.
