Industrial Wastewater Discharges to a POTW: Am I Regulated?

If you are a categorical industrial user (CIU) discharging process wastewater to a publicly owned treatment works(POTW), you will be regulated by either the local POTW who owns the sewer system or us.

To determine who is responsible for regulating your wastewater discharges to the POTW you will need to know:

• Does the POTW have an approved pretreatment program? See our list of approved Texas Pollutant Discharge Elimination System (TPDES) pretreatment programs to find out.

• If the POTW does not have an approved pretreatment program, does it have additional requirements?
