Answer: Most sources indicate no tree should be planted close to the drain field as their roots will infiltrate the area and in times of drought grow into the pipes in search of moisture and clog or possibly even break them. Typical distance suggested is about 50 feet. Maple trees are somewhat notorious for having spreading, aggressive root systems and also for preferring a damp soil. A typical tree will send roots out about twice as wide as its branch spread. Your local county extension may have suggestions of trees you could try, but the rule of thumb is lawn or shallow rooted plants only near the drainfield.
