On-Site Sewage Facilities Program (OSSF)

The term "on-site sewage facility" (OSSF) refers to all types of systems used for sewage disposal on a single property. A conventional septic system is just one of several systems available. The type of system suitable for a property depends on the soil type, site characteristics, physical features, and the property's intended uses.

Program Information

The OSSF program serves as the designated representative for McLennan County to implement and enforce the rules adopted under the Texas Health and Safety Code, Chapter 366, and Title 30 TAC, Chapter 285, On-Site Sewage Facilities. Through an agreement between the City of Waco and McLennan County, the Health District administers the program for McLennan County, the cities in McLennan County, and the City of Waco. The division is also responsible for investigating and resolving complaints regarding on-site sewage facilities. The OSSF program is comprehensive because its goal is to eliminate and prevent health hazards and pollution to our county’s sewage disposal systems.
