Soil and Percolation Evaluation: what to know

How well your soil drains decides what kind of field can go on your lot.

Before a new or replacement drain field is designed, someone has to find out how the ground on your lot handles water. That usually means looking at the soil layers, how fast water moves through them and how high the water table sits during wet months.

North Central Florida has plenty of sandy soil, and in some places the water table sits close to the surface. Those conditions can limit what is allowed and where. The soil work is what tells a designer whether a standard field will fit or whether something else is needed.

We connect Gainesville-area homeowners with local pros. We do not do soil testing ourselves. You can ask the county health department which parts of the evaluation it handles and which parts a contractor handles.

Questions to ask a pro

  • What will you test, and where on my lot?
  • How do you decide where the water table is in the wet season?
  • Does the county need to be on site?
  • What does the report say, and who keeps a copy?
Check before you hire: Before you hire anyone, ask for their Florida license or registration number and check it with the state. Ask for proof of liability coverage, a written scope of work and a written contract. Septic work in Florida generally needs a permit, so ask who pulls it.

Common questions

Why does the water table matter for a drain field?

A drain field works by letting treated liquid soak down through soil. If groundwater sits too close to the pipes, there is not enough soil to do that, and the rules limit what can be built.

Is soil testing needed for a replacement?

Often some site evaluation is needed because conditions or rules may have changed since the first system went in. Ask the county health department what applies to your lot.
