Requesting an Exception to Rules and Regulations for Public Water Systems
A public water system (PWS) that does not meet a TCEQ design standard may request an exception by proposing another way it can meet the intent of the rules. We review each exception request to ensure that, if granted, the PWS will still deliver safe drinking water to its customers at adequate pressures.
Membrane Challenge Studies
Public water systems with membrane filtration systems for removing Cryptosporidium and Giardia must receive approval from the TCEQ to evaluate each membrane’s ability to remove pathogens. The filtration systems impacted by this requirement are those that were installed or replaced after April 1, 2012.
