Sand is not the whole story
Almost every argument about a septic system is really an argument about soil. Get that part right and the rest of it is paperwork.
Baldwin County is coastal plain: sand and sandy loam over sandier material, and on paper that is exactly what a drainfield wants. The catch is the water underneath it. Across much of the county, and almost everywhere south of the Intracoastal, the seasonal high water table sits close enough to the surface that there is very little unsaturated soil left to do the treating. Fast soil over shallow water is not a good septic site. It is a site that moves effluent quickly into groundwater, which is precisely what the separation rules exist to stop.
A conventional system is three jobs in a row, and only the first two are equipment. The tank separates, the distribution box shares the flow out, and then the soil itself does the treating. When people say a septic system failed, what they nearly always mean is that the third part stopped working, because the ground was never able to do the job it was being asked to do.
The test that decides everything
A licensed evaluator is not guessing and is not consulting a map. They put holes in your ground and watch what water does. Two lots on the same street can come back with completely different answers, which is exactly why nobody can quote you honestly over the phone.
What that leaves you with
On a Baldwin County lot the limiting number is almost never how fast water moves sideways. It is how far down the saturated zone begins, because trench bottoms may not sit below the ASHES indicators and the soil above them is all the treatment you get. Where that margin is thin, the field is built up above natural grade as a mound, or the water is treated mechanically before it is released. Near the coast, storm surge and flood zone add a second set of constraints on top of the first.
Not us, not a contractor on the phone, not a soil survey. The design follows the boring log. That is why the evaluation is the first thing you pay for, and why a quote given before one is worth precisely nothing. Get local pros to quote the evaluation →
What it costs
Ranges we would expect to see quoted on the coastal plain, not a price list and not a quote. Alabama fees are set locally and installed costs are not published by anyone, including us. Where a job lands is decided by the boring and by how far above the water table the field has to be built.

Common questions
Do I need a permit to install or replace a system?
Yes, and it is not a formality. the Baldwin County Health Department is the local health department that issues the permit and makes the site determinations, applying the rules the Alabama Department of Public Health writes for the whole state. Work that goes in without one is work that has to come back out, and it will show up again the day you try to sell.
How much does a new system cost here?
For most local lots the honest answer is a range, not a number. The bars on our cost page show what each system type typically runs installed. Where your job lands inside them is decided by the soil boring, not by the house.
How long does the whole process take?
Weeks, not days. The evaluation, the design, the review and the inspection each wait on somebody else's calendar. Homeowners who start early are the ones who avoid delaying a build or a closing.
Can you tell me what my lot needs?
No, and neither can anyone else who has not dug a hole on it. Soil maps are a starting point and nothing more. The design follows the boring log, which is why the evaluation is the first thing you pay for rather than the last.
