Stagnation of water within a building can be caused by prolonged shutdown or reduced operations. The CDC and American Water Works Association have developed guidelines on how to address stagnation when reopening buildings to employees and the public. Please note that if chemical injection is utilized in a public water system treatment plant or distribution system, plans and specifications are required to be submitted to the TCEQ Plan and Technical Review Section.

For more information about the TCEQ approval process for drinking water treatment, email the TCEQ Plan and Technical Review Section.
