Will I be able to irrigate or have horses where my Soil Treatment Area (STA) is located?
Tri-County recommends that an absorption field area be left largely untouched by homeowners. Irrigated landscaping is not recommended, since it has the possibility to saturate an absorption area causing the septic system to fail prematurely. You may consider planting buffalo grass or other natural grasses which do not require irrigation. Mow any grasses planted on the absorption area regularly. Horses or other livestock should not be placed on an absorption area, because compaction of the soils may occur causing premature failure of your absorption area. We also have a guide on septic care and maintenance.
