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 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.
