On-Site Sewage Facilities Program (OSSF)
The term on-site sewage facility (OSSF) is used to address all types of systems that may be used for sewage disposal on a piece of property. A conventional septic system is just one of several systems available. The type of system suitable for a property is dependent upon the soils, site characteristics, physical features, and the intended uses of the property.
Program Information
The OSSF program is 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 in nature because the goal is to eliminate and prevent health hazards and pollution to our county’s sewage disposal systems.
