Planting Trees Near a Water Line: No Need to Fear

Tree Roots and Water Pipes: Myths vs. Reality

You’re hesitant to plant trees because the city water line is 3.5 feet deep. Rest easy: sealed water pipes are not invaded by tree roots. Roots may grow around them but won’t penetrate intact pipes. Only leaking sewer or septic lines attract roots. Your list—plums, pears, golden rain tree, cherries, lilac, serviceberry, redbud, smoke tree, maple, dove tree, hazel—are all fine choices. Taproots and lateral roots alike will simply divert around the pipe.

Pick the tree that fits your design goals (flowers, shade, fall color) and plant with confidence.
