Expert installation of new septic systems for new construction, replacements, and property upgrades — with full permitting and soil testing
New Construction, Replacement, or Upgrade
Whether you're building a new home on the Old Mission Peninsula, replacing a failed system on a Leelanau County lakefront property, or upgrading an aging cesspool near Kingsley to a modern septic system, the installation process in Grand Traverse County is shaped by one overriding factor: the soil beneath your feet. And in this part of northern Michigan, that soil varies from plot to plot more than almost anywhere else in the state.
At Grand Traverse Septic, we've been installing septic systems across Grand Traverse County for over 30 years. We know the soil maps for every township — from the well-drained sandy loams along the Boardman River valley to the tighter, finer-textured soils on the peninsula and the variable glacial deposits south of Kingsley. We've permitted and installed systems on properties that three different installers said couldn't be developed. And we've replaced dozens of failed systems that were originally installed without considering the specific soil and site conditions that define Grand Traverse County.

Every septic system installation in Grand Traverse County starts with a soil test. This isn't optional — the Grand Traverse County Health Department requires a site evaluation before any new or replacement system can be permitted. Here's what that involves:
Soil Borings: We dig test pits or perform hand auger borings across your property to determine the soil profile. We're looking for the depth to the seasonal high water table, the depth to restrictive layers (bedrock, dense clay, or hardpan), and the soil texture classification. In Grand Traverse County, we typically see 4 to 6 feet of usable soil depth before encountering water table limitations, but it varies dramatically by location.
Percolation Testing (Perc Test): In some cases, the county requires a percolation test to measure how quickly water moves through your native soil. The standard for a conventional gravity system in Grand Traverse County is a percolation rate between 5 and 60 minutes per inch. If your soil perc rates faster than 5 min/inch (very rare in this region but possible in pure sand deposits), the effluent moves too quickly to be treated. If slower than 60 min/inch, the soil can't absorb effluent fast enough, and an alternative system type — like a mound system — is required.
Lot Size and Setback Verification: We verify that your property meets the minimum lot size requirements and that all proposed system locations comply with setback distances: 50 feet from wells, 25 feet from surface waters, 10 feet from property lines, and 10 feet from building foundations.
The type of system that's right for your property depends on your soil conditions, lot constraints, budget, and household needs. Here are the most common systems we install in Grand Traverse County:
The simplest and most cost-effective option — and the right choice when your soil has adequate depth and drainage. A conventional system uses a septic tank connected to a series of perforated pipes laid in gravel-filled trenches. Effluent flows by gravity through the pipes and into the surrounding soil for natural treatment.
Best for: Properties with deep, well-drained soils and adequate lot space. Common in the Kingsley area and newer subdivisions south of Traverse City where the soil profiles are favorable.
Cost range: $3,000-$7,000 depending on size and site conditions
Chamber systems use plastic arched units instead of gravel to create the absorption area. They require less excavation, have a smaller footprint, and perform better during high-water-table conditions because the chamber itself provides some storage volume. Chamber systems have become the standard for new construction in Grand Traverse County over the past decade.
Best for: Most residential properties in Traverse City and suburban Grand Traverse County. An excellent upgrade from gravel systems on moderately challenging sites.
Cost range: $5,000-$10,000
A mound system creates an elevated absorption field using imported sand fill. The system pumps effluent up into the mound, where it filters through the sand before entering the native soil below. Mound systems are the standard solution for Grand Traverse County properties with shallow soils, high water tables, or slow perc rates — which describes a significant portion of the lakefront properties on East Bay, West Bay, and the Leelanau shoreline.
Best for: Lakefront properties, lots with high water tables, and sites where conventional systems can't meet separation distance requirements. Common on the Old Mission Peninsula and Leelanau County shoreline.
Cost range: $8,000-$18,000
Aerobic systems use oxygen to break down waste more effectively than traditional anaerobic septic processes. They produce cleaner effluent and can be paired with smaller drain fields or spray irrigation systems. While less common in Grand Traverse County than in other parts of Michigan, they're becoming more popular for environmentally sensitive sites and properties with very restrictive lot sizes.
Best for: Small lots, environmentally sensitive areas near surface water, and properties where a conventional drain field isn't feasible.
Cost range: $10,000-$20,000
LPP systems use small-diameter pipes with precisely spaced orifices to distribute effluent evenly across the drain field. The small pump doses the field in controlled batches rather than allowing gravity to flood the entire system at once. This gives the soil time to rest and absorb between doses, making LPP systems excellent for variable soil conditions.
Best for: Sites with uneven terrain, variable soil types, or where you want the most even distribution possible to maximize drain field life.
Cost range: $7,000-$14,000
Grand Traverse County requires a septic permit before any installation work begins. We handle the entire permitting process — submitting the site evaluation results, system design, and site plan to the Environmental Health Division of the Grand Traverse County Health Department. Permit fees typically range from $250 to $500 and are included in our project management. The review process takes 1 to 3 weeks depending on county workload and the complexity of your site.
We stake out the system location, mark all utility lines (Miss Dig — 811), and clear the installation area. For replacement systems, we pump and remove the old tank and decommission the old drain field according to county requirements.
For a typical residential system, the excavation and installation takes 1 to 3 days. We excavate to the required depths — which in Grand Traverse County must provide a minimum 36 inches of separation between the bottom of the drain field trench and any limiting layer (seasonal high water table or bedrock). We install the tank, set the baffles, attach the outlet filter, lay the drain field piping or chambers, backfill carefully to avoid soil compaction, and restore the site.
A county health department inspector visits the site to verify that the installation matches the approved plan. We schedule the inspection at the point when the system is fully installed but not yet backfilled in the drain field area — the inspector needs to see the pipes or chambers and the separation distance before approving the final cover. Once approved, we complete the backfill and final grading.
Many of our installation projects in Grand Traverse County start with a time-of-transfer inspection. Here's the scenario: A home is under contract, the buyer's inspection reveals a failing or substandard septic system, and the county requires a replacement before the sale can close. These projects are time-sensitive — we've completed emergency replacements in as little as 48 hours when the sale timeline demanded it.
If you're buying or selling a home in Grand Traverse County, we strongly recommend having a proactive septic inspection before listing. Identifying a failed system before a buyer's inspection gives you time to get competitive bids and choose the right system — rather than making a rushed decision under a tight deadline.
