Have you had your home's septic system inspected for flood damage in the past year?
A 350-gallon graywater septic tank popped out of the ground at a Palm Bay, Florida home during flooding this week. The Florida Department of Health in Brevard County issued a flood safety warning about septic system dangers.
Why it matters
The incident shows that buried septic components can be pushed out of the ground by high groundwater even when most of a property is not underwater. The health department's warning highlights the risks flooding poses to residents who rely on septic systems in Palm Bay and across Brevard County.
The 350-gallon tank, installed about five years ago, is being replaced with a 50-gallon unit at an estimated cost of $3,000. It is not yet known how many other septic systems in the area were damaged by the flooding.
The players
Florida Department of Health in Brevard County
The county arm of the state health agency that issues septic system guidance and oversees on-site sewage treatment for Brevard County residents.
The details
The tank collects water from sinks, showers, washing machines and other household plumbing and pumps it to a second tank connected to the drain field. High groundwater created enough buoyant force to lift the buried tank even though most of the homeowner's yard was not underwater.
Timeline
Monday: Nearby streets and neighboring properties flooded.
Tuesday: The Florida Department of Health in Brevard County issued its flood safety warning on septic systems.
Thursday: Replacement of the 350-gallon tank with a 50-gallon tank is scheduled.
Seasonal Patterns
Flooding that affects buried septic components is governed by Florida's county-administered on-site sewage rules, which apply to the state's large population of homes outside municipal sewer lines. The Palm Bay incident fits a wet-season pattern in which high groundwater repeatedly tests these systems across Brevard County.
Homeowners with septic systems should have buried tanks inspected after flooding to confirm they remain anchored and functioning. Residents who suspect septic damage should contact the Florida Department of Health in Brevard County for guidance.
The takeaway
Septic tanks can rise out of the ground when groundwater is high, even if a yard appears dry. Checking tank anchoring and pump function after heavy rain can prevent costly failures.
