Statewide cost drivers here are high water tables and clay soils. Locally, high water tables require mounds or aerobic systems with drain fields raised. That is why a chamber system in Florida can land well above or below the national range of $5,000–$11,000.

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