On-Site Sewage

On-Site Sewage Facility Permit

An On-Site Sewage Facility is a wastewater treatment and disposal system that treats and disposes of no more than 5,000 gallons of sewage per day. (View EPA website for more information). State law requires property owners and on-site sewage facility installers to possess an on-site sewage facility permit issued by the City of Grand Prairie before an on-site sewage facility is constructed, altered, or repaired.

Regulatory Authority

The City of Grand Prairie is an Authorized Agent of The Texas Commission on Environmental Quality (TCEQ). The program falls primarily under the authority of TCEQ rules contained within 30 TAC Chapter 285 On-Site Sewage Facilities. Additional regulatory authority is derived from Texas Health and Safety Code, Title 5, Section C, Chapter 341, and Section D, Chapter 366 of Sanitation and Environmental Quality. In the City regulations can be found in Ordinance 7512 or in Chapter 13 Section 190.

OSSF Maintenance Practices

  • The excessive use of garbage grinders and grease discharges should be avoided. Garbage grinders can cause a rapid buildup of sludge or scum resulting in more frequent septic tank treatment unit pumping or failing.
  • Do not use the toilet to dispose of cleaning tissues, paper towels, cigarette butts or other trash. This disposal practice will waste water and increase the amount of undesired solids into the treatment system.
  • Septic tank (s) should be inspected at least once a year and pumped when necessary. Treatment tanks should at least be pumped at 2 or 3 year intervals. Sludge or scum can accumulate allowing solids to leave treatment tanks clogging drainfields or causing sewage to back up into plumbing fixtures. Chemical additives or enzymes are not necessary for the operation of a septic tank. Chemicals should not be used to clean septic tanks.
  • Commercial septic tank pumping companies can pump out tanks. State law requires owners of on-site sewage facilities to employ only persons registered as liquid waste haulers with the Texas Commission on Environmental Quality to pump out on-site sewage facility treatment tanks.
  • Do not build driveways, storage building or other structures over the treatment tanks or drainfields.
  • Soaps, detergents, bleaches, drain cleaners, and other household cleaning materials normally used will have no appreciable adverse effect on the operation of septic tanks. Moderation is recommended.
