Technical Review and Assistance

Technical Assistance for Public Water Systems: TROT program

The Technical Review and Oversight Team (TROT) protects public health by providing technical assistance to every public water system (PWS), consulting engineers, and internal customers. This assistance includes helping PWSs with source water development, design, treatment, and operations.

Requesting an Exception to Rules and Regulations for Public Water Systems

A public water system (PWS) that does not meet a TCEQ standard (rule) in Title 30 of the Texas Administrative Code (30 TAC) Chapter 290 Subchapter D may request an exception by proposing another way it can meet the intent of the rule. We review each exception request to ensure that, if granted, the exception allows the PWS to still deliver safe drinking water to its customers at adequate pressures.

Map of Water Systems under Water Use Restriction

Long Term 2 Enhanced Surface Water Treatment Rule

Information regarding the Long Term 2 Enhanced Surface Water Treatment Rule (LT2) source water monitoring for public water systems. The purpose of the LT2 rule is to reduce illness linked with the contaminant Cryptosporidium and other disease-causing microorganisms in drinking water. The rule supplements existing regulations by targeting additional Cryptosporidium treatment requirements to water sources that show higher Cryptosporidium levels.

Membrane Challenge Studies, Cartridge Filter Systems, and Alternative Membrane Filter Monitoring

Public water systems with membrane and cartridge filtration systems for removing Cryptosporidium and Giardia must receive approval from the TCEQ to evaluate each membrane’s ability to remove pathogens. The membrane filtration systems impacted by this requirement are those that were installed or replaced after April 1, 2012. Alternative methods to monitor membrane filters are allowed.
