On-Site Sewage Facility (OSSF) Inspection and Maintenance Requirements

All OSSF permits issued must comply with SJRA’s approved Order Adopting Rules for OSSFs within 2,075 feet of Lake Conroe. Below is an excerpt from the Order:

Effective June 1, 2016, the inspection and maintenance of all OSSFs identified as Aerobic Treatment Units must be performed by a maintenance provider, licensed by the TCEQ, under a written contract between the property owner served by the OSSF and such TCEQ-licensed maintenance provider, with one exception. If the OSSF serves a single family dwelling that is the primary residence of the property owner, the property owner may conduct the maintenance, provided.

  1. the property owner is a maintenance provider licensed by the TCEQ;
  2. the property owner holds a valid Class D or higher wastewater treatment license;
  3. the property owner has satisfactorily completed the OSSF – Aerobic/Surface Application System Operation and Maintenance Course entitled – General Guidance for Monitoring Aerobic Treatment Units, Disinfection Units, and Spray Fields in Texas (B-6235) offered by the Agrilife Extension, Texas A&M System; or
  4. the property owner has satisfactorily completed any other TCEQ-approved Aerobic system Maintenance Provider Course.

The property owner will need to complete a contract with the SJRA for homeowner maintenance. This contract can be obtained online at or in the Lake Conroe Division Office. SJRA will then provide the property owner with an inspection tag that is to be placed on the facility in an easily accessible location. At each inspection (once, every four months) the tag must be dated and initialed by the property owner. A detailed report (available at the above link) must also be submitted to SJRA within 14 days of each inspection.

Training can be obtained from many different sources. The following are examples of approved courses:

  1. Environmental Training Systems-Troubleshooting Aerobic Treatment Units Course
    • 8 hour course
  2. Texas Engineering Extension Service (TEEX)-Aerobic Surface Application System Operation and Maintenance Course
    • 8 hour course
  3. Texas On-Site Wastewater Association (TOWA)-Basic Maintenance Provider Course
    • 16 hour course (Must pass the exam)
