Low ground, heavy rain and a high water table are ordinary facts of life out here, and they need managing rather than ignoring.
Wet ground for months at a time
Land near the creeks and the edge of the Francis Marion holds water for long stretches. That standing water sits under houses, around outbuildings and across the ground your septic field depends on.
Crawl spaces and outbuildings
Keeping water off floor framing, ductwork and insulation is the main job. Workshops, well houses and storage buildings matter too — an inch of water round a pressure tank or pump control is a genuine problem rather than an inconvenience.
No power, no pump
The same problem as your well. Storms bring rain and outages together, and out here the power stays off longer. A pump with no battery backup, or a generator that can carry it, is off exactly when the water is rising.
Test yours before hurricane season
Pour a bucket into the pit and check it starts, clears it and stops cleanly. Two minutes in June is worth a great deal in September.
