How do you abandon a septic tank?

Sunday, January 19, 2020

A septic tank that is no longer connected to a house plumbing system and drainfield, and is no longer being maintained, is a biological hazard if not properly abandoned. Florida requires an abandonment permit from the Department of Health, which costs $75, but not all states specify a permit (and inspection) for the work. Here’s how it’s stated in Chapter 64E-6.011 of the Florida Administrative Code:

 "Whenever the use of an onsite sewage treatment and disposal system is discontinued following connection to a sanitary sewer, following condemnation or demolition or removal or destruction of a building or property or discontinuing use of a septic tank and replacement with another septic tank, the system shall be abandoned within 90 days and any further use of the system for any purpose shall be prohibited.”

    The tank must be pumped out by a licensed septage hauler, then either collapsed or punctured so that it will not hold water, hole filled with clean sand to grade, and then you can call for a final inspection. When you call for the final, be sure to have the receipt for pumping available for the inspector.
