Statewide cost drivers here are hard ground, terrain and remote access. Locally, mountain terrain and freeze depth affect tank depth and insulation. That is why a chamber system in Colorado can land well above or below the national range of $5,000–$11,000.

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