Arborvitae Planting Distance from Septic Tank

Needs windbreak near septic tank. Gifted pyramidal arborvitae (3-4 ft diameter). How close to 4000-gallon concrete tank?

No Fixed Distance—Risk Management

Plant as close as needed, but: septic access requires excavation. Roots over tank complicate digging. Cutting roots near trunk may kill tree. Tank typically 1-2 feet deep.

Decision Framework

• Further = better for future maintenance
• Problems may not arise for many years
• Balance immediate screening need vs. long-term risk
