Running a Public Water System 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.
Under TCEQ rules (30 TAC §290.38), a Public Water System is any system meeting either of these thresholds:

RV parks, glamping and event venues, wineries, churches, camps, shopping centers, and office/warehouse complexes are common surprises. If that sounds like you, you probably need to be operating as a PWS. We can help.
The work TCEQ cares about: monitoring plans, sampling, reports. We do it.
Our TCEQ‑licensed operators track your monitoring plan, submit your reports, and keep your system in good standing with the agency.
We design and operate treatment that meets TCEQ standards so the water leaving your system is safe to drink.
We do the sampling, meter reads, data entry, and reports.
Every system is different. We size our involvement to your monitoring plan, your staff, and your budget.

Resorts, campgrounds, commercial sites, and small municipalities across the Hill Country.
No cookie‑cutter packages.
You talk to the operator on your account, not a call center.
Hard water and scale cost businesses money: equipment that fails sooner, products that suffer, customers who notice. Trinity designs and maintains commercial water treatment systems sized to your operation.
Spotless glassware, better coffee, and the confidence that the water serving your guests is clean.
Filtration that fights scale and corrosion. Fewer breakdowns, longer equipment life.
A single café or a multi‑building resort. Fixed install or mobile, designed to your spec.
If your facility hits the PWS thresholds (15+ service connections, or 25+ people for 60+ days a year), we can operate it under TCEQ rules on top of providing treatment.
Send us a few details about your facility and water challenge. We'll come back with a plan.
Trinity Water Treatment is a Public Water System management and commercial water treatment company serving Greater San Antonio and the Texas Hill Country. We're licensed by TCEQ as a Water Operations Company, with a Class III Water Treatment Specialist and Class D Water Operators on staff — credentials that let us design your system, install it, operate it, and file the reports.
TCEQ regulates every Public Water System 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 all three credentials: a Water Operations Company license at the LLC level, a Class III Treatment Specialist (Drake), and Class D 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.
Treatment systems engineered for your water: wells, RO, filtration, distribution.
