Grants that cut the bill
- Brevard: $6,000 to $20,000 per parcel toward an ENR upgrade, and up to $12,000 (gravity) or $24,000 (with a pump) toward a sewer connection, approved before work starts. Brevard septic grant.
- Indian River County: up to $15,000 toward a sewer connection where sewer is available, announced; the application portal had not opened as of November 1, 2026. Indian River County help.

Cost guides
- What a septic system replacement costs: why the real price inside the program area is usually the ENR price, with Brevard's installed averages.
- What a drainfield replacement costs: permit fees, when a drainfield job becomes a new system, and why upgrading may be the better spend before 2030.
- What it costs to connect to sewer, utility by utility: connection and impact fees, typical owner totals and payment plans for each utility in the four counties.
- Septic pumping and the 2030 rule and septic repairs before 2030.
Paying for the rest
- County and utility plans: some sewer projects let owners pay over time through an assessment, for example North Hutchinson Island in St. Lucie County, or through utility financing.
- Contractor payment: in Brevard the county can pay an approved grant to your contractor directly, so you only finance the difference.
- Your own loan: a home equity loan or line of credit is a common route; compare the rate and fees with any program offer first.
Since July 2024, Florida's PACE law also covers septic upgrades and sewer connections, repaid on the property tax bill where your county or city allows it. Compare every option on septic financing and loans.
The calculator's monthly figure uses the rate and term you type in. It is an example, not a loan offer.
