Who determines if I need a mound septic system?
I own a lot which I plan on building a house. I was told by a friend of mine that I will probably need to have a mounded septic system. My lot is high and dry it never flooded during the heavy rains we had recently so I do not want a mound. A: Chapter 64E-6 of the Florida Administrative Code requires a 24 inch separation between the wet season water table and the bottom of the drainfield. Water tables can fluctuate drastically between rainy and dry seasons. Wet season water tables are determined by looking at the color and texture of the soil, USDA soil survey maps, and vegetation in the area. Once the water table is established then a permit is written to meet State code requirements. If the 24 inch separation to the water table requires that the drainfield be mounded then it will require stabilization with 6 to 18 inches of soil cover and 4 foot shoulders on all sides of the drainfield material. If sod will be used on the slopes then a 2:1 slope is required for mounds up to 36 inches
