North Sebastian Phase 3 Community Meeting
Wednesday, June 17, 2026 at 5:30 p.m.
North Indian River County Library, Large Meeting Room, 1001 Sebastian Boulevard, Sebastian, FL 32958
The Indian River County Department of Utility Services (IRCDUS) will host a community meeting to provide information about the upcoming North Sebastian Phase 3 Septic-to-Sewer Project. Phase 3 properties are located in the vicinity of Roseland Road, Old Dixie Highway, and North Indian River Drive. The meeting will take place on Wednesday, June 17, 2026, beginning at 5:30 p.m., at the North Indian River County Library, Large Meeting Room, 1001 Sebastian Boulevard, Sebastian, Florida. Project information will be on display and members of the project team will be on hand to answer questions. Discussion will also include the potential installation of new water main infrastructure to expand drinking water service in the area.

What Is the Septic-to-Sewer Program?
Indian River County's Septic-to-Sewer Program is replacing older residential septic systems with connections to the county's centralized sewer system. Septic systems in areas near the Indian River Lagoon can contribute excess nutrients — particularly nitrogen and phosphorus — to local waterways, which harms water quality and aquatic ecosystems.
By connecting homes to centralized sewer, the county can significantly reduce nutrient pollution reaching the lagoon while also providing homeowners with a reliable, modern utility connection that eliminates the need for individual septic system maintenance. The program currently includes four active projects across the county, each serving a different neighborhood.
How Does This Help The Indian River Lagoon?
Many homes in Indian River County were built with individual septic systems before centralized sewer was available in their area. While these systems were adequate at the time, they contribute nutrients to the groundwater that eventually reaches the Indian River Lagoon.
The Indian River Lagoon is one of the most biologically diverse estuaries in North America, stretching 156 miles along Florida's east coast. Excess nitrogen and phosphorus from septic systems, stormwater, and other sources have degraded water quality in the lagoon over the past several decades. Converting homes from septic to sewer is one of the most effective ways to reduce nutrient loading and support the lagoon's recovery.
Indian River County has prioritized neighborhoods where the environmental benefit is greatest — areas closest to the lagoon and its tributaries, where septic systems have the most direct impact on water quality. To learn more, please enjoy our short informational video.

Time: 0:07 – 0:33
For decades, septic tank systems have been collecting, treating, and disposing wastewater. When residents flush the toilet, take a shower, or brush their teeth, wastewater flows into the septic tank and the drain field then percolates into the soil where it is absorbed. Indian River County has sandy soils and seasonal rainfall that causes the groundwater tables to rise.
Time: 0:34 – 1:11
This may result in nitrogen, phosphorus, and bacteria migrating from the septic systems into water bodies, which can negatively impact water quality and the ecosystem. Septic system failures can result in sewage backups and limit recreational activities like fishing, swimming, and boating. When residents convert from septic systems to a wastewater collection system, wastewater is safely treated, which enhances the environmental stewardship, resiliency, and sustainability of water resources.

Benefits of Connecting to Centralized Sewer
Converting from septic to sewer provides significant advantages for the environment, homeowners, and public health.
Environmental Protection
- Reduces nitrogen and phosphorus entering the Indian River Lagoon and local waterways
- Eliminates the risk of septic system failures contaminating groundwater and surface water
- Supports long-term water quality goals for the Indian River Lagoon ecosystem
Homeowner Benefits
- Eliminates the risk of costly septic system repairs or replacements
- Connection to a reliable, professionally maintained county sewer system
- May increase property value
Public Health
- Reduces potential exposure to raw sewage
- Protects drinking water sources by reducing groundwater contamination
Mandatory Connection Policy
When a septic-to-sewer project is completed in your area, connection to the county sewer system is mandatory. Indian River County ordinance requires properties within the service area of a completed sewer project to connect to the centralized system and properly abandon their existing septic system.
The county provides advance notice and a connection timeline for each project area. Homeowners will receive information about the connection process, applicable fees, and any available financial assistance before the connection deadline.
