What Is an OSSF Septic System in Texas?
An On-Site Sewage Facility (OSSF) is a septic system used for properties that are not connected to municipal sewer service. In Austin and throughout Central Texas, OSSF systems must be designed and approved based on soil conditions, property layout, and local county regulations before installation can begin.
Proper septic system design is critical to ensure long-term performance, environmental compliance, and successful permit approval.
