Septic-to-sewer conversion in Cutler Bay: the short answer

Most of Cutler Bay is already on public sewer, so a septic-to-sewer conversion here is often the simplest fix for one of the town's remaining 371 septic parcels. Where a gravity sewer runs past the lot, you need a new lateral, a plumbing permit, utility approval and a Department of Health permit to pump out and abandon the tank.

Because sewer reaches so much of the town, many Cutler Bay septic owners already have a line at the street. Florida law gives a working system 365 days to connect after the utility's written notice, and a system that needs repair 90 days after the Health Department's notice.

Homestead single-family owners may qualify for up to $15,000 in grants or low-interest loans from the County's Septic-to-Sewer Financial Assistance Program. It needs a gravity sewer abutting the property and a County-approved plumber, and it is first come, first served.
