On-Site Sewage Facilities (OSSF) are wastewater disposal systems designed to treat and dispose of effluent (wastewater from kitchens, bathrooms, and laundry) on the same property that produces it. An OSSF is more commonly referred to as “septic system”. A permit will be required for all OSSF’s, regardless of the size of the lot or acreage onto which it is installed.
Before building, altering, extending or operating an OSSF, a person must have a License to Operate from Guadalupe County Environmental Health Department or from TCEQ.
