Septic Tank Pumping in Delray Beach, FL

Is your Delray Beach home on septic or city sewer?

Delray Beach and Boynton Beach jointly own the South Central Regional Wastewater Treatment and Disposal Facility. It treats about 17 million gallons of sewage a day from the two cities. Most homes inside the city limits drain to it. The state inventory lists fewer than 1 in 100 residential parcels there as septic.

Outside the city, the septic parcels cluster in ZIP codes 33484 and 33446. Nearly all of them are single-family lots. So a Delray Beach mailing address alone does not tell you whether a house is on sewer.

Delray Beach sand and the summer water table

The West Settler's Historic District was first called the Sands, named for its sandy soil. Federal NRCS soil maps show two kinds of sand around Delray Beach. East of I-95, much of the ground is St. Lucie and Paola sand that drains too fast to filter well. To the west lie flat, poorly drained sands such as Myakka and Immokalee.

Most septic homes with Delray Beach addresses sit on those western sands. Checked against NRCS soil maps, about three in four of those septic parcels lie on Myakka or Immokalee fine sand. For more than nine in ten, the NRCS water table rises to within about a foot of the surface. NRCS rates Myakka and Immokalee very limited for septic drain fields.

That high water comes with the wet season, which the National Weather Service dates May 15 to October 15. By April and May, NRCS data puts it about four feet down. When the sand around a drain field is soaked, wastewater can back up into the house. If a toilet backs up after a summer storm, call or text and ask about emergency septic service.

Septic permits and state rules in Palm Beach County

Septic permits for Delray Beach homes come from the Florida Department of Health in Palm Beach County. The state's environmental agency took over the rules in July 2021, and the county office still issues permits. Under state rules, septic tank repair on a failing system needs a permit. A routine pump-out does not count as a repair.

A repair permit application has to show the estimated water table during the wettest season of the year. State rules keep the bottom of a drain field at least 24 inches above that water table. Where it sits about a foot down, the drain field may need to be built up on approved fill. Before anyone digs, Florida law calls for an 811 ticket at least two full business days ahead.

Older Delray Beach homes and historic districts

Delray Beach has about 37,400 homes, and about half were built in the 1970s and 1980s. The median home dates to 1983, per the Census Bureau's American Community Survey. About one in three is a detached single-family house. Most of the rest are townhomes and units in multifamily buildings.

The oldest streets go back further. The city's preservation guidelines date Del-Ida Park to 1923 and most Marina Historic District buildings to between 1922 and 1943. If a house that old still has a septic tank, a septic tank inspection shows its condition.

Inside the city limits, building permits go through the Building Division of the city's Development Services department. Septic permits come from the county health office, inside the city and out.
