Tompkins septic work needs the OWTS permit page before construction
Tompkins County says new or repaired onsite wastewater systems need a county permit before construction work begins.

Tompkins County gives septic work a clear sequence, and that sequence is worth reading before anyone starts digging.
A permit is needed before constructing a new OWTS or making repairs to an existing system. OWTS is the official shorthand here: onsite wastewater treatment system.
The process described by the county includes application, site and soil investigation, permit issuance, installation, inspection, and certificate steps. That is not a casual checklist to discover halfway through a repair.
For a homeowner, the order is the story. A contractor estimate, soil information, site plan, permit, inspection, and final certificate all need room in the timeline.
This is especially important when a septic issue is tied to a home sale, addition, bedroom question, or failed system. The county process gives people a way to slow the problem down and handle it in order.

Tompkins County Whole Health, Environmental Health, OWTS, the installer, and the parcel should stay in the same thread. Ithaca, Dryden, Lansing, Caroline, and other Tompkins towns all benefit from a septic file that keeps county steps visible.
