Frequently Asked Questions: Drilling Wells in Michigan
1. How deep do you usually have to drill for water in Michigan?
Across Michigan, the median residential water well is drilled to 140 feet. However, shallow alluvial wells can hit water as high as 40 feet, while deep bedrock or limestone aquifer wells may require drilling down to 420 feet to reach sufficient pressure and yield.
2. How much does a complete water well cost in Michigan?
On average, homeowners in Michigan invest $7,900 USD for a complete turnkey system. Drilling alone costs $38 per foot (ranging $28–$62/ft), while submersible pumps, pressure tanks, state permit fees ($110), and electrical hookups comprise the remaining balance.
3. What is the required setback from septic tanks in Michigan?
State health mandates overseen by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) require a minimum separation distance of 50 feet from any septic tank, leach field, or potential contamination source, plus at least 10 feet from adjacent property boundaries.
4. What is the groundwater quality like in Michigan?
Wells in Michigan typically yield water with a hardness reading around 230 PPM and an average pH of 7.4. Key minerals present in natural groundwater include Hardness, Iron, Arsenic in Thumb Region. The recommended standard filtration configuration is: Arsenic Selective Media + Water Softener.
