Tips for Charlotte Homeowners

Plan for red clay soil challenges. Charlotte's clay-rich Piedmont soils drain poorly. Your system design must account for this — don't try to install a conventional gravity system where soils won't support it.

Get a soil evaluation early. If you're buying land to build on, invest in a soil evaluation before closing. Unbuildable lots (no suitable soil for septic) are a real risk in the Carolinas.

Budget for regular inspections. North Carolina recommends inspecting your system every 1–3 years, even between pumping appointments.
