Septic Drainfield Care: Protect the Part You Cannot See
Simple rules for water, landscaping, traffic and drainage that protect septic drainfield function.
The drainfield is buried but central to wastewater treatment. Protecting soil structure and keeping excess water away can extend reliable operation.
Keep heavy loads off
EPA advises against driving or building over most drainfields. Compaction and crushed components can be expensive to correct.
Manage surface water
Downspouts, sump discharge and grading should not send extra water onto the field.
Use appropriate vegetation
Shallow-rooted grass is common. Deep or aggressive roots can damage components and complicate access.
Keep a system drawing
Knowing tank and drainfield locations prevents accidental construction, landscaping or traffic damage.
