What to know here
- Install without a permit and the county doubles the fee — no exceptions.
- This office also handles 100-year floodplain permits and private well water analysis ($90).
- Homeowners may self-maintain an aerobic system after the initial two-year policy only with TCEQ maintenance-technician training or an approved homeowner course, a $20 annual registration, and reporting every four months.
Still being filled in. Filing method and the affidavit/CAD/911 sequence are not yet documented here. County processes change without notice — call before you rely on anything here, and tell us if you find something out of date.

Before you call the county
Most permit applications need the same core set of documents: a site evaluation by a licensed site evaluator or professional engineer, planning materials showing the proposed system and its layout, a plat or survey with the legal description, a confirmed 911 address, the applicable fee, and a recorded affidavit to the public where the system type requires one. Aerobic systems also need an executed maintenance contract.
Details on each step are on the permitting page, and the design page covers what a site evaluation involves.
