New build volume
Columbia County carries a lot of the region growth. That means most septic work here is new installation rather than repair, and it means the permit is on the critical path of a build schedule rather than an afterthought.
Twelve month permit clock
A Georgia construction permit expires after twelve months. On a subdivision where lots are released in phases, permits pulled too early expire before the house gets built. We time them properly.
Inspection before backfill
The county inspects before the system is covered. On a tight build schedule that inspection has to be booked, not hoped for. Missing it means uncovering a finished system.
Bedroom count drives everything
Tank capacity follows bedroom count, 1,000 gallons to four bedrooms and 250 gallons per bedroom after. Change the house plan and the septic design changes with it.
