Wastewater Discharges from Water Treatment Plants: Am I Regulated?

Find out if your water treatment plant needs authorization under General Permit TXG640000 or an individual permit to discharge wastewater.

If you operate a Water Treatment Plant and you plan to discharge wastewater into water in the state of Texas or land apply the wastewater adjacent to water in the state, you must have a permit authorization.

There are two types of permits available: the Individual Permit and the Water Treatment Plant General Permit TXG640000.

  • You may qualify for coverage under the Water Treatment Plant General Permit TXG640000 Microsoft Word Document if your facility generates wastewater as a result of conventional water treatment. See if you qualify for this general permit at Applying for Authorization under the Water Treatment Plant General Permit.
  • You must obtain an individual permit for any discharge released, if you don't qualify for authorization under the general permit or your facility generates wastewater as a result of either of the following: 
    • Reverse osmosis, ion exchange, or any other desalination process.
    • Water treatment processes regulated in Title 30, Texas Administrative Code 290.42(g), except ultraviolet light.
