Merritt Island and the 2030 septic rule

Yes. Merritt Island is unincorporated Brevard County between the Indian River and the Banana River. Our count finds essentially all of about 7,200 septic parcels in ZIP codes 32952 and 32953 inside FDEP's program-area map. Central and south Merritt Island fall in the Banana River plan area; the north end is in the North Indian River Lagoon plan area.

How we counted (November 1, 2026): parcels the Florida Water Management Inventory (FLWMI, Florida Department of Health) marks as known, likely or somewhat likely septic, by physical-address ZIP code, counted only where the parcel touches FDEP's program-area map. Parcels, not homes, and ZIP codes do not match community lines exactly. See our data. Check your own address below; the result also shows which plan area you are in.

Under Florida law, by July 1, 2030 homes on 10 acres or less with septic in the program area must connect to sewer if it is available, or upgrade to an enhanced nutrient reducing (ENR) system that removes at least 65% of nitrogen. The statute has no penalty clause. Since January 1, 2024 a new septic system in the area must be ENR, and no new septic is allowed where sewer is available.

Merritt Island had a local rule first. On October 9, 2018 Brevard County passed an ordinance requiring advanced treatment septic systems (65% or greater nitrogen removal) on the barrier islands, both the beaches and Merritt Island. Ask the Florida Department of Health in Brevard County what your permit requires before you plan any septic work.

The sewer projects on Merritt Island are Brevard County projects. Call Brevard County Utilities at (321) 633-2091 to ask whether sewer is available at your address. The county's Save Our Indian River Lagoon story map, tab 4, shows planned septic to sewer areas.

The county's status list (updated June 9, 2025):

Design can take 12 to 36 months and construction 10 to 18 months, the county says. If no project reaches you, the 2030 path is an ENR system. See ENR vs sewer.

State lagoon grants to Brevard County for Merritt Island area sewer zones:

• Merritt Island Zone C $1,900,000, Zone F $2,000,000 and Zone G $10,327,172 (2023-24)
• Sykes Creek Zone T $6,000,000 (2023-24)
• North Merritt Island Zone E $9,288,516 and Sykes Creek Zone M $3,859,716 (2024-25)

These pay for pipe in the street, not your yard. For owners:

• Brevard sewer quick connect grant: $1,600 per pound of nitrogen prevented, up to $12,000 for a gravity connection and up to $24,000 where a pump or force main is needed. In the county utility area it can pay the connection fee directly. Plumbing under the foundation is not covered.
• Brevard septic upgrade grant: at least $6,000 and up to $20,000 per parcel for an ENR upgrade. WUSF described a Merritt Island parcel sending 27 pounds of nitrogen a year that qualified for the full $20,000; the neighbor at 3 pounds qualified for about $2,500 before the $6,000 minimum was set. Details: Brevard septic grant guide.

Apply by emailing [email protected] or calling (321) 633-2016, and get approved before work starts.

WUSF reported the average Brevard ENR upgrade at more than $22,000 in late 2025, up from $18,000 in 2020, before any grant. A sewer connection depends on whether your street gets gravity, vacuum or force main sewer and how far the tank is from the line.

If your system fails first, a repair is the natural moment to upgrade, and the permit office will remind you of the 2030 rule. Since July 1, 2026 the health department must tell owners about the rule on any repair, modification or replacement application. For the Banana River area FDEP's February 2026 table lists no ENR requirement for an ordinary repair. On the north end, the North IRL repair listing came from a federal court order that the 11th Circuit vacated on October 8, 2026 (details). The county's 2018 ordinance still applies on Merritt Island, so ask the Florida Department of Health in Brevard County what your permit requires. More in septic repair.
