Nixon does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

    On-site sewage facilities, including septic systems and holding tanks, inside Nixon city limits where an OSSF is used.

    • The permitting authority may apply more stringent local requirements.

Unanswered questions are usually a sign that Nixon publishes no rule on the point, not that none exists. Gonzales County’s page lists the county offices to call.
