Drainfield basics for homeowners
A plain-English overview of what the septic drainfield does.
Short answer
A drainfield disperses and treats wastewater after it leaves the septic tank. Homeowners should protect the area from heavy vehicles, structures, excess water, and deep-rooted plantings, and should ask professionals about property-specific concerns.
Checklist
- Know the approximate drainfield area.
- Avoid driving or building over it.
- Direct roof and surface water away when appropriate.
- Call a professional if the area is wet, smelly, or unusually lush.
