Other Rules That Apply to Public Water Systems

Public water systems should also be aware of other rules pertaining to drinking water that are contained in other parts of the Texas regulations. A public water system must comply with all the applicable requirements. Some examples of additional rules and their location within the regulations are:

  • Requirements for water districts. Contact the Districts Section at 512/239-4691 if you have questions about these requirements. 30 TAC Chapter 293  
  • Requirements for certification of water works operators. These requirements will be relocated to 30 TAC Chapter 290, Subchapter A, in the near future. The Operator Certification Team (512/239-6300) can answer questions about these requirements. 30 TAC Chapter 30, Subchapter K

Who enforces these rules?

The Texas Commission on Environmental Quality (TCEQ) is responsible for enforcing these rules in Texas. On September 1, 2002, the Texas Natural Resource Conservation Commission (TNRCC) became the TCEQ. This name change does not affect the permits, registrations, or any other paperwork or transactions any water system has had with this commission in the past.
