Bonneau | Lake Moultrie ground, and the water table that comes with it
⚡ Site evaluations are booked within a few working days; a failing system that is surfacing gets looked at sooner.
- What the soil will actually accept, measured not assumed
- Permit drawn and filed with SCDES, not left to you
- A written scope that says what happens if the water table wins
Bonneau is a small Berkeley County town of a few hundred people on the southern approach to Lake Moultrie. It is the furthest north we regularly work and it presents the hardest ground conditions on this list — high water, tight setbacks from surface water, and a number of properties that started life as seasonal cabins and are now lived in year round.

Seasonal buildings, full-time loads
A system permitted for weekend use and now carrying a permanent household is running well over its design load, and it fails accordingly. Resizing is usually the honest answer rather than repairing.
Expect a mound
Close to the lake, separation is frequently too short for a conventional field and an above-grade system is the only thing that will pass. Budget for that possibility from the outset rather than being surprised by the evaluation.
