Septic Tank Laws in Central Florida

A septic tank is a term often used to describe what is really a septic system, with the tank being one of the two main elements. A septic system has a tank which retains and collects solids and a drainfield where liquid effluent is distributed. Septic tanks come in different sizes and septic systems come in different designs to fit local soil conditions and are prevalent mainly out in the country or small towns where there is no central sewer system. In central Florida there are strict laws governing septic system design.

The Tank

• Acceptable septic tanks in Central Florida and most of the United States are made from concrete and are transported to the site on a truck. Each county has its own laws regarding septic tanks, but the general rules in Central Florida call for a 750-gallon tank minimum size for a 2-bedroom home, 900 gallons for a 3-bedroom house, 1,000 gallons for a 4-bedroom house and plus 250 gallons for each additional bedroom.

Location

• In Central Florida no septic system may be placed closer than 75 feet from a well. This can cause problems on small lots as there often is not enough space for a well and a septic or the neighbor's well may be located in a place that does not allow for a septic system in your lot. It is very important to have an expert determine if you will be able to fit a septic system and a well on your lot before buying.

Permits

• No septic system in Central Florida may be built without a permit. All septic systems must be designed by a qualified engineer and soil tests have to be done before a permit will be issued. The soil test will determine what type of system will work best in each location. If the soil percolates at the required rate, a conventional system will most likely be approved. The groundwater level is high in most of Central Florida, and homeowners often have to install a mound system above ground or other more expensive designs containing pumps and electronic devices.
