Best Perc Test in Howell, MI

What is a perc test and why do I need one in Michigan?

A perc test (percolation test) measures how quickly water drains through soil. It is required before installing any new septic system and is conducted under the oversight of your county health department. MDHHS's Michigan Criteria for Subsurface Sewage Disposal sets the soil evaluation standards that govern the percolation testing process statewide.

How much does a perc test cost in Michigan?

A perc test typically costs $500 to $1,500, including soil profile evaluation. Municipal fees for health officer oversight add $100-$400. Total costs vary based on regional regulatory requirements and professional standards.

What happens if my property fails the perc test in Michigan?

If conventional perc test results do not meet state standards, you may be able to install an alternative system (mound system, drip irrigation, FAST unit) if site conditions allow. In densely developed areas, failing lots may have no viable septic option, requiring connection to public sewer if available.

Who can perform a perc test in Michigan?

Soil evaluations and perc tests must be conducted by a licensed soil evaluator or Licensed Professional Engineer (PE) approved by your county health department. The evaluation must be witnessed by a county health officer.
