Hanahan | Reservoir ground and older post-war systems
⚡ 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
Hanahan, about 22,000 people, occupies the neck of land between the Cooper River and the Goose Creek Reservoir in Berkeley County. Much of the older housing dates from the post-war expansion around the Navy yard, and the systems under it are of the same era. Proximity to surface water tightens setbacks here in a way it does not further inland.

Setbacks near the water
A drain field has to keep its distance from surface water and wells, and on the smaller lots close to the reservoir that requirement plus the replacement area can be the binding constraint. This is worth establishing at the soil evaluation before any budget is set.
Old systems, small lots
Tanks from the fifties and sixties with corroded lids are common, and a soft lid is the one genuine safety hazard in this trade — see septic tank repair.
