Preventing drain field failure requires protecting the drainage area and the reserve property. Driving vehicles or heavy equipment over the field causes compaction of the soil and increases the chances of failure. Owners should limit landscaping over the drain field to grass and should never pave over it.

Pumping the septic tank every three to five years prevents leaking of solid materials into the leach field. Septic tanks have baffles that normally trap these materials in the tank. However, if the system becomes overloaded, solids flow through the baffles into the field and cause damage.

Signs of a failing drain field include standing water, odors and soggy soil in the area. Often the additional moisture causes the grass to grow with green strips over the leach lines. Inside the home, occupants often notice fixtures draining slowly and gurgling noises from drains.
