Chamber Septic System Cost

Typical installed range: $5,000 – $11,000

What it is

Chamber systems replace gravel with plastic chambers. They are lighter, faster to install and work well on sites where gravel delivery is expensive.

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.
