COMMONLY ASKED QUESTIONS

Frequently Asked Questions: Drilling Wells in Louisiana

1. How deep do you usually have to drill for water in Louisiana?

Across Louisiana, the median residential water well is drilled to 180 feet. However, shallow alluvial wells can hit water as high as 50 feet, while deep bedrock or limestone aquifer wells may require drilling down to 450 feet to reach sufficient pressure and yield.

2. How much does a complete water well cost in Louisiana?

On average, homeowners in Louisiana invest $8,100 USD for a complete turnkey system. Drilling alone costs $35 per foot (ranging $26–$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 Louisiana?

State health mandates overseen by the Louisiana Department of Natural Resources (LDNR) - Office of Conservation 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 Louisiana?

Wells in Louisiana typically yield water with a hardness reading around 80 PPM and an average pH of 7.0. Key minerals present in natural groundwater include Iron, Manganese, Color / Tannins in delta. The recommended standard filtration configuration is: Iron & Tannin Reduction Filter.
