My husband and I will be building soon in Florida. Our property will require a septic mound for the drainfield. We have three options to make everything flow properly through the septic system and I'm not sure which route is the best way to go.
Option 1: Build the house at the current ground level. Install the septic tank in the ground below the level of the house. Put in a sump pump (or would it be an ejector pump?) to pump the water from the septic tank into the drainfield. This is probably the cheapest route short-term, but, I'm not sure how the pump would effect our electric bill and the long-term maintenance costs of a septic pump.
Option 2: We can haul in dirt and build our house on a mound of dirt. Our septic tank would sit at the current ground level, putting it below the house, and feed into the drainfield. No pump would be required. This option is the next-in-price option, but I don't really want my house sitting on a mound of dirt. There are many houses in this area that do that (including our current house) and I just don't like the look, so I'm pretty much ruling out this option.
Option 3: Build a stem wall for the house, fill it with dirt, then pour concrete slab. OR, we could have a crawl space with floor joists, however my husband is concerned with termites getting to the floor. This option would put the house up above the septic, the same as in option 2. This is probably the most expensive option.
Any suggestions or comments regarding these different systems or maybe some other alternative that we don't know about?
