Frequently Asked Questions: Drilling Wells in Mississippi
1. How deep do you usually have to drill for water in Mississippi?
Across Mississippi, the median residential water well is drilled to 170 feet. However, shallow alluvial wells can hit water as high as 45 feet, while deep bedrock or limestone aquifer wells may require drilling down to 480 feet to reach sufficient pressure and yield.
2. How much does a complete water well cost in Mississippi?
On average, homeowners in Mississippi invest $7,800 USD for a complete turnkey system. Drilling alone costs $34 per foot (ranging $25–$56/ft), while submersible pumps, pressure tanks, state permit fees ($100), and electrical hookups comprise the remaining balance.
3. What is the required setback from septic tanks in Mississippi?
State health mandates overseen by the Mississippi Department of Environmental Quality (MDEQ) require a minimum separation distance of 100 feet from any septic tank, leach field, or potential contamination source, plus at least 15 feet from adjacent property boundaries.
4. What is the groundwater quality like in Mississippi?
Wells in Mississippi typically yield water with a hardness reading around 70 PPM and an average pH of 6.8. Key minerals present in natural groundwater include Iron, Low Hardness, Acidity in southern sand. The recommended standard filtration configuration is: Iron Filter + Neutralizer.
