What is the minimum separation distance between a water well and a property line?

• A. 3 feet
• B. 7 feet
• C. 12 feet
• D. 5 feet

Answer: (D)

A water well needs a small safety buffer from property lines to protect the well’s water quality and allow proper construction and future maintenance. The rule sets a minimum distance so that activities on neighboring properties, and any potential movement of soil or groundwater, are less likely to contaminate the well. Measuring from the outside of the well casing to the property line, the smallest allowed distance is five feet. This provides just enough space for proper well installation, sealing, and access for servicing, while still allowing you to place the well on your lot. Remember that local codes can add other setback requirements (from septic systems, streams, or buried utilities), so always verify any additional rules in your area.
