Running a Public Water System (PWS) means staying on top of TCEQ rules and reporting deadlines that don't forgive mistakes. Trinity's licensed operators take that work off your plate so your water stays compliant and safe.

RV parks, glamping and event venues, wineries, churches, camps, shopping centers, and office/warehouse complexes are commonly public water systems. If that sounds like you, you probably need to be operating as a PWS. We can help.

You talk to the operator on your account, not a call center.
Trinity Water Treatment is a Public Water System (PWS) management and commercial water treatment company. Our TCEQ credentials include Class III Water Treatment Specialist, and Licensed Water Operators. These credentials allow us to design your system, install it, operate it, and file the reports.
TCEQ regulates every PWS in Texas. Operating one legally requires a licensed Water Operator, and any active treatment — filtration, disinfection, RO — calls for a Water Treatment Specialist on top of that. Trinity holds three credentials: a Water Operations Company, a licensed Class III Treatment Specialist, and licensed Water Operators on the team. Plenty of water companies sell you equipment and walk. We operate your system under our TCEQ approval and keep you compliant year after year.
