AI-assisted, code-bound, provenance-tracked OWTS design — driven by live soils, flood, wetland, terrain and parcel data, and reviewed against 10 NYCRR Appendix 75-A.
Every step reads and writes the same property twin — so nothing is re-keyed, and the design carries its evidence from intake to as-built.
Homeowner enters an address; Septic Sam reads the aerial and prices the difficulty before anyone drives out.
Pick the lot, pull live terrain + 8 GIS coverages, place the system, and solve the hydraulic grade line.
Layer QAQC, cross-layer consistency, and an independent audit against Appendix 75-A — then the PE seals.
Contractor field package, phone-GPS as-built capture, and a QR-tagged lifetime record.
From the public front door to the sealed submission set.
Homeowner intake — address → their parcel → a free Septic Sam preliminary read. Pre-qualified leads.
Draft the design proposal — Sam prices difficulty, the engine shows your margin before you send.
Live parcel + terrain + coverages, auto-placed bed, hydraulic profile, T1–C4 submission set.
Independent recompute + red-flag scan → ACCEPT / RETURN / REJECT for the code officer.
Phone-GPS field package — stake the system, capture the as-built, close the loop.
Three-dimensional terrain + system view — hypsometric mesh, fill mound, earthwork.
Global settings, labor rates & fee tuning, service health, leads, and the encrypted API-key vault.
