New septic system installation in Brevard County / the Space Coast
Whether it's a new build, a replacement for a failed system, or land you're evaluating before you buy, the sequence is the same: soil first, then design, then permit, then install.
Cost: $8,000–$15,000 for a conventional system. Engineered systems (mound, drip, aerobic) run higher — see the cost guide for the local ranges.
What decides the price
- Soil. The single biggest variable. Well-draining soil supports a simple gravity field; slow-draining or shallow soil forces a larger field or an engineered system.
- Bedrooms. Systems are sized by bedroom count.
- Lot access and terrain. Flat and open is cheap; wooded hillside means slower machine work and sometimes a pump chamber.
- Permit and inspections. County fees are modest; the contractor's design and inspection coordination are part of the quote.
Steps
- Site evaluation and soil test with the county
- System design and permit application
- Installation — tank, field or unit, pump chamber if required
- County final inspection before backfill and use
New construction inside the Indian River Lagoon program area must meet the 65% nitrogen-reduction standard from the start, and there is currently a court-ordered moratorium on new septic permits in the North Indian River Lagoon. If you're building in north county, the permit conversation comes first. Elsewhere in Brevard, sandy soil supports conventional systems but the water table often forces a raised drainfield. Florida's statutory fee schedule caps most DOH permit line items between $25 and $125.
Buying land? A site evaluation before closing tells you what a system will cost — or whether the lot will support one at all.
All work is performed by Florida-registered septic tank contractors who are licensed and insured.
