Septic-to-Sewer Program — Indian River County, Florida

As of October 12, 2026, the Indian River County Department of Utility Services lists four neighborhood conversions, at Floravon Shores, North Sebastian, Wabasso Island and Hobart Landing, plus a countywide Sewer Connection Assistance Program.

Each job carries a utility project number and a phase from a seven-step scale that runs from procurement through design, permitting, bidding, construction and closeout to complete (county Septic-to-Sewer Program). Floravon Shores Phase 2, project 21.19.556 on 110th Street, is the furthest along: 19 homes close to the lagoon shore, a community meeting on March 31, 2026, and construction bids open through contractor award.

The largest neighborhood job is North Sebastian Phase 3, project 21.26.505, which takes in 168 homes on streets around North Sebastian, with engineering and design underway (Indian River County Septic-to-Sewer page). Hobart Landing, project 21.24.508, is smaller at approximately 53 homes, and the county says three quarters of its cost comes from the state. The Wabasso Island job, project 41.24.507, pairs septic removal with utility improvements and was still soliciting qualifications for an engineering firm or design-build team.

The Indian River County Department of Utility Services serves the unincorporated county, runs the conversions in North Sebastian and treats Fellsmere's wastewater in bulk, while the City of Vero Beach runs its own system with its own conversion rules.

The county utility's reach is large. Its collection system takes wastewater from approximately 34,000 retail service connections in unincorporated Indian River County, and the same Department of Utility Services provides bulk sewer treatment service to the City of Fellsmere (IRCDUS rate study, page 5). That flow goes to four active wastewater treatment facilities with a combined permitted treatment capacity of 12.02 MGD. On the water side, the utility serves about 56,000 retail customers (IRCDUS rate study site).

Vero Beach is the exception inside the county. The city converts homes with a septic tank effluent pump, or STEP, system and its Ordinance No. 2024-05 requires connection to a central sewer system by June 1, 2028 or within one year of the sale, conveyance or transfer of a property served by septic (City of Vero Beach Ordinance 2024-05). The council chose the earlier date to allow for a more organized transition from a septic system to a STEP System, and to help residents who cannot connect before the state deadline of July 1, 2030.

Enforcement in Vero Beach runs through city code. After June 1, 2028, or a year after a sale, an owner who has not connected is in violation, and the utility director notifies the city's Code Enforcement Officer (Ordinance 2024-05, page 3). Septic owners outside Vero Beach, in places such as North Sebastian, Wabasso Island or Floravon Shores, deal with the county program instead.

Indian River County pays for conversions through its utility enterprise fund, which runs on customer rates rather than taxes, topped up by Florida Department of Environmental Protection grants for jobs such as Hobart Landing.

Indian River County Utilities states that its operations and capital improvements are funded exclusively through user fees (not through taxes), and that rate increases took effect January 1, 2025 with a second on October 1, 2025 (IRCDUS rate study site). The consultant's financial plan behind those increases set the sewer rate plan at 24.00% for FY 2025 and 12.00% for FY 2026 (IRCDUS rate study, page 60). The same plan assumes an additional 100 Septic to Sewer (S2S) connections per year when it projects revenue (IRCDUS rate study, page 49).

Grant money lowers the cost to owners on specific jobs. A state FDEP grant covers 75% of Hobart Landing, and the Sewer Connection Assistance Program will pay eligible owners up to $15,000 each, from FDEP grant money, to hook up where a county line already runs past the lot in the utility's north, central or south service areas (Indian River County Septic-to-Sewer page). On October 12, 2026 the county was still introducing that program ahead of the application portal opening.

The capital plan shows where the large dollars sit. The Sebastian Highlands carry three septic-to-sewer lines in the FY 2024 to FY 2034 Capital Improvement Program, with Unit 05 the largest at $22,670,872 (IRCDUS rate study, page 58). Orchid Island No.2 is budgeted at $9,900,000 and Hobart Landing Unit 2 at $4,400,000, while smaller lines cover North Sebastian Phase 2, Floravon Shores and West Wabasso Phase 3A. Septic work competes in that schedule with other utility jobs, such as $1,829,521 for the North County 24-inch force main replacement and $5,193,994 for Oslo water treatment plant improvements, both in FY 2024.

Who sets the rates matters for every customer on the county system, from Wabasso to the South County service area. The Board of County Commissioners has periodically conducted formal rate studies, and the one before the FY 2024 study was completed in 2018 (IRCDUS rate study, page 5). The utility's own comparison puts its FY 2024 residential water and sewer charges the lowest of 14 peer utilities, with the highest more than twice as much (IRCDUS rate study site).

Under section 381.00655 of the Florida Statutes, an owner whose septic system works properly must connect to an available public sewer, such as an Indian River County Utilities line, within 365 days of the utility's written notice.

The statute builds in warning time. A public utility must tell the owner no less than 1 year before the sewer line will become available that the connection will be required within 1 year of actual availability (Section 381.00655, Florida Statutes). For a North Sebastian, Hobart Landing or Wabasso Island owner, that means two notices: one at least a year before the line becomes available, and the availability notice that starts the 365 days.

Payment can be spread out, including for an Indian River County Utilities connection. The same section gives the owner the option of prepaying the amortized value of required connection charges in equal monthly installments over a period not to exceed 2 years from the initial notice of anticipated availability (Section 381.00655).

A failing tank moves faster. When a septic system needs repair to function in a sanitary manner, its owner must connect to an available public sewer within 90 days after written notification from the department, and in hardship cases one extension of not more than 90 days may be approved (Section 381.00655). That rule applies equally in Fellsmere, Sebastian and the unincorporated county wherever a line runs past the property.

By July 1, 2030, Florida's lagoon law requires septic properties in its plan areas, including the Central Indian River Lagoon basin plan that Vero Beach Ordinance 2024-05 cites, to connect to available sewer or cut nitrogen by at least 65 percent.

Section 373.469, the Indian River Lagoon Protection Program, reaches every commercial lot, and every home lot of 10 acres or less, still on septic inside four plan areas: the Banana River, Central Indian River Lagoon and North Indian River Lagoon basin plans and the Mosquito Lagoon plan (Section 373.469, Florida Statutes). New septic systems have been prohibited in those areas since January 1, 2024 where a public sewer is available.

Where no Indian River County Utilities line reaches the lot, the route is an upgrade rather than a hookup. The statute authorizes only enhanced nutrient-reducing onsite systems, or other treatment systems that achieve at least 65 percent nitrogen reduction, in places where central sewer is not available (Section 373.469). Before July 1, 2030, any agency handling an application to repair or replace a conventional system must tell the owner about the deadline.

The county's own sequencing follows the lagoon. Its program site says the county has prioritized neighborhoods closest to the Indian River Lagoon and its tributaries, where septic systems have the most direct impact on water quality (county Septic-to-Sewer Program).
