Septic and sewer
On septic in Sebastian? A state deadline is less than four years away.
By July 1, 2030, most septic tanks near the lagoon must connect to sewer or be upgraded. In Sebastian, your sewer comes from the county, not the city.
If your house in Sebastian sits on a septic tank, a 2023 state law sets the clock. Under the Indian River Lagoon Protection Program, by July 1, 2030, an existing septic system in the program area must connect to central sewer where it is available, or be upgraded to an enhanced system that removes at least 65% of the nitrogen. Since January 1, 2024, every new septic system in the area has had to be that enhanced type.
One thing surprises a lot of Sebastian owners: the City of Sebastian does not run the sewer. Indian River County provides sewer service here, so the letters, the connection rules and the assistance program all come from the county.
County staff gave these ranges at public workshops in September: $5,000 to $8,000 to connect to a gravity sewer main, $11,000 to more than $20,000 when a lift or grinder pump is needed, and $15,000 to $25,000 to retrofit an existing tank to the enhanced type. The county is setting up a Sewer Connection Assistance Program of up to $15,000 per eligible property; as of early October it had not opened for applications.
Along the waterfront, the city and county have been extending sewer lines through Sebastian’s Community Redevelopment Area so every parcel there can connect. A Florida Department of Environmental Protection grant helps residents and businesses in that area with the cost of closing the septic tank and hooking up.
What to do this month: look up your address on the county’s program site, ircs2sprogram.com; open every letter from county utilities; and get more than one price from a licensed plumber. Questions go to the county program team at 772-770-5300.
