roper maintenance of your septic tank system includes disposal area care.
 

• Do not drive over your disposal area with automobiles, trucks, or heavy equipment unless your disposal area is specifically designed for these loads.

• Maintain adequate vegetation or mulch over the disposal area unless the field has been designed under pavement.

• Avoid sitting gardens over disposal areas, because annual rotary tilling tends to erode the surface cover.  Rotary tiller tines can cut into the disposal pipes and units.

• Avoid tying dogs, who are inclined to dig, over disposal areas.  Avoid sitting horse or cattle corrals over fields due to foot impact and erosion potential.

• Vegetation with aggressive shallow root systems should not be grown near systems (willow trees, for example).
