Got a soggy yard in Mason, MI, or the greater Lansing area? If your property’s clay-heavy soils or high water table (hello, Grand River floods!) rule out a standard septic system, a mound type septic system might just save the day.

What Is a Mound Type Septic System? 💧
A mound type septic system is a raised wastewater solution built for properties where traditional septic systems can’t cut it. Think of it as a smart workaround for Mason’s tricky soils.
Here’s the deal:
Septic Tank: Collects your home’s wastewater, letting solids settle.
Dose Tank: Sends liquid effluent to the mound with a low-pressure pump.
The Mound: A layered pile of sand, gravel, and soil filters the effluent, letting nature’s bacteria do the cleanup before it hits groundwater.
In Mid-Michigan’s wet conditions—where water tables can creep right up to the surface in spring—mounds shine by keeping wastewater safely above groundwater. But strict Michigan Department of Environment, Great Lakes, and Energy (EGLE) rules mean mounds need up to 4 feet of isolation, which can make them taller and pricier, requiring hundreds of tons of soil to build them. Don’t worry—we’ll show you how Michigan Septic shrinks those costs (and mound heights!).
Why Choose a Mound Septic System in Mid-Michigan? 🌊
Ingham, Eaton, Jackson, and Clinton County’s clay soils and proximity to the Grand River and Red Cedar River make mound type septic systems a go-to for homes in Mason, Dimondale, Eaton Rapids, or Stockbridge. Just like the challenging sites we tackle daily, these systems handle high water tables like champs, ensuring EGLE compliance without flood risks.
Here’s why they’re a fit:
Soggy Soil Savior: Perfect for low-lying lots near Holt or Okemos where water pools.
Eco-Friendly: Protects local waterways from nutrient pollution—think cleaner rivers for our community.
Built to Last: With routine septic tank pumping every 3-5 years, mounds can serve for 30 years or more.
The catch? Our area’s tight water table isolation rules (thanks, spring thaws!) can mean taller mounds, eating up yard space and boosting the cost for mound septic system. But with smarter designs, we can cut that height and keep your lawn looking sharp—more on that below.
What Drives Mound Septic System Cost in Michigan? 💰
The cost for mound septic system varies based on your property’s specifics. Here’s a breakdown of what impacts the price for a typical Mason home:
Got unusual terrain or trees blocking access? Add 10-20% for extra labor. Fences, lakes, streams, small yards, and many other factors may quickly compound costs due to logistics.
Curious if a repair could dodge the mound entirely? Our team’s modern tech can sometimes fix existing systems for a fraction of the mound septic system cost.

Shrinking Mound Heights with Alternative Designs 🌱
The biggest downside to mound type septic systems? Those bulky mounds, driven by Michigan’s strict 4 foot water table isolation rules. In Mason’s soggy springs, standard mounds can tower 3-5 feet, cramping your yard’s style. But our area’s high water tables don’t have to mean a mini-mountain in your backyard.
Michigan Septic’s in-house team uses approved alternatives to cut mound heights by 20% or more:
Tailored Mound System Engineering: We work with your specific situation and design a system that's optimized for your needs, and your wallet. No copy and paste systems here.
Alternative System Technologies: Approved alternatives to the huge mega-mounds are smaller, shorter, and require a lot less material (read: more money back in your pocket).
These tweaks save on materials (fewer truckloads from local quarries!) and blend into your landscape, keeping your Mason or Holt yard looking pristine. We handle every step—soil tests, permits, inspections—no subcontractors, no surprises.
