On-Site Sewage Facilities (OSSF) are wastewater systems designed to treat and dispose of effluent on the same property that produces the wastewater. Most people know them as septic systems. Regular maintenance and inspection of OSSF protects public and environmental health, increases system longevity, and enhances private property use and value.
H-GAC offers various programs, workshops, and resources for real estate professionals, homeowners, and the public.
