On-Site Sewage Facilities (OSSF)

Did you know?

  • According to TCEQ, in many parts of Texas, soil analyses are ruling out conventional systems where liquids are separated from solids in the septic tank and then spread throughout the drainfield by means of underground pipes or other proprietary products. Organic wastes are treated as the liquids percolate through the soil. But most soils in Texas can't properly absorb pollutants, so alternative treatment methods are required.
  • Almost all OSSFs must have a permit prior to any construction, installation, repair, extension, or other alteration. Any work on an OSSF must be performed by a licensed installer or directly by the homeowner when it is their single-family residence. If someone is paid for any part of the process, that person must be licensed by the state.
  • As a Health District our boundaries are not limited to the county limits; Lakes Arrowhead and Kickapoo are the city’s main source of water, as such we have a vested interest in keeping our water clean. Therefore, we inspect the city leased lots at the lakes in these counties.

The City of Wichita Falls approved a local ordinance in 1989 to establish additional standards for the construction, operation, and maintenance of an on-site sewage facility (OSSF). Designated Representatives permit new and existing OSSFs to assure they adhere to these regulations:
