Wells should be located at least 75 feet from any part of a septic tank system. Septic tanks and drainfields must be also be located at least 75 feet away from the high water line of natural bodies of water such as ponds, lakes or rivers. Runoff from roof gutters and surface drainage patterns must be taken into consideration when siting a drainfield location so that it will not become saturated by surface water. Site Evaluations are often done by Health Department personnel, but can also be done by licensed Master Septic Tank Contractors . Florida Code requires that the bottom of the drainfield be 24 inches above the water table so some systems will need fill to raise the area where the drainfield will be installed.
Mounds are more expensive than a standard below grade drainfield and require much more space.
Every effort should be made to locate your system in an area that does not require a mound. On some lots there is no other option except to use a mounded system. However, by careful selection of the areas chosen for the site evaluation you may avoid having to install a mound. As a Master Septic Tank Contractor , Anthony Gaudio can perform the site evaluation and select the best location for your system. The elements of a mounded system are listed below.
