Sand filter Septic System Cost

Typical installed range: $8,000 – $16,000

What it is

A sand filter treats effluent before it reaches the drain field, which helps on poor soil. It adds cost and requires scheduled maintenance.

When you need it

Regulations vary by state and county. In general, this system is required when a conventional drain field is not allowed by soil, water table or setback rules. Your local health department makes that determination after a soil test.
