On-Site Sewage Facilities Program (OSSF)
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 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 an individual piece of property is dependant upon the soils, site characteristics, physical features and the intended uses of the property.
The OSSF program is comprehensive in nature since the goal is to eliminate and prevent health hazards and pollution. The staff members achieve this goal by regulating, permitting, planning, and inspecting the location, design, construction, installation, operation and maintenance of all on-site sewage disposal systems. The division is responsible for investigating and resolving complaints regarding on-site sewage facilities (septic systems).
The office is located at 401 Franklin Avenue on the first floor of the City of Waco Mae Jackson Development Center. The office telephone number is 254-299-2405. Hours of operation are from 8 a.m. to 5 p.m. Monday through Friday.
