How Much Does It Cost to Replace a Septic System in Livingston County, MI?

If you own a home in Livingston County, MI, chances are you rely on a septic system to handle wastewater. Like any system, septic tanks and drain fields don’t last forever. Eventually, they may need to be repaired or replaced. One of the most common questions homeowners ask is: “How much does it cost to replace a septic system in Livingston County?”

The short answer is: $8,000 to $18,000+ depending on your system type, soil conditions, and project complexity. Let’s break down the factors that influence the price so you know what to expect.

Average Septic Replacement Costs in Livingston County, MI

• Conventional septic system: $8,000 – $12,000

• Mound system or sand filter: $12,000 – $20,000+

• Advanced treatment systems (aerobic, RioVation, etc.): $15,000 – $25,000+

Prices can vary significantly depending on your property size, soil quality, and whether excavation is needed.

Key Factors That Affect the Cost

   • Alternative systems (sand filters, aerobic treatment, mound systems) cost more but may be required depending on soil conditions.

2. Tank Size

3. Soil Conditions & Perk Test

   • Clay or poor-draining soils often require engineered solutions, raising the price.

4. Permitting & Regulations

   • In Livingston County, the local health department requires inspections and permits for septic replacement. Fees vary but should be factored into your budget.

5. Accessibility of Your Property

   • If your tank or drain field is in a difficult-to-access area, excavation may take longer, increasing costs.
