What kind of trees can I plant near the septic system?

The best ground cover over a drain field is a well maintained grass cover. While it is not recommended, an owner may choose to plant trees near the drain field area. The exact location of the drain lines need to be known so that a tree is not planted on top of the drain line.


Most modern drain fields have only 6 to 12 inches of back fill over them, and the pipe and trench can be damaged by planting trees too close or on top of the drain line. If trees are planted near the drain field, you should avoid species that are known to have problem roots. These species include:

  • Any tree with fibrous roots.
  • Elms
  • Maples
  • Sweet gum
  • Willows
