Sites in San Antonio need water, wastewater, and well equipment that works the same way on Monday morning as it does on Friday night — and a reliable water, wastewater, pump, and control system service partner who can help it get there.
Welch Industries, LLC, supports San Antonio customers who care about uptime, clear information, and fixes that hold up. Our team is comfortable around residential and commercial wells, pumps, motors, controls, and monitoring equipment, providing comprehensive solutions that address both immediate problems and long-term system performance.

We look at how your San Antonio well is actually being used, test the equipment, and sort out why performance slipped, then make repairs that put the system back on solid footing instead of just resetting the same issue.

If the system feels like it’s working too hard for the results you’re getting, we check the pump, motor, and pressure tank together. From pump maintenance to repairs, we address weak points so the setup can operate with less strain and more consistency.

Controls should make decisions easier, not harder. We clean up wiring, settings, and hardware on your water and wastewater control systems so what you see on the panel matches what’s happening in the field.

San Antonio heat is already enough to manage without fighting irrigation issues. We handle the pump and control side so your system runs on schedule, at the right pressure.

We add or refine monitoring, automation, and alerts so you get a clearer picture of how your systems are behaving and earlier notice when something starts drifting away from normal.

Once everything is stable, we help you decide what should be checked, adjusted, or serviced on a schedule so pumps, motors, tanks, and controls stay reliable instead of going from one emergency to the next.

Complex sites can involve wells, pumps, motors, pressure equipment, controls, irrigation systems, and monitoring technology working together. Our broad experience helps us evaluate how those components interact instead of treating every issue as an isolated equipment failure.

How a system performs under actual demand matters. We consider equipment condition, system behavior, and how the site operates when diagnosing problems, allowing us to recommend repairs and adjustments based on what's actually happening in the field.

Our work doesn't have to end once the immediate problem is resolved. From preventative maintenance and pump maintenance to controls, monitoring, and system improvements, we help San Antonio clients keep critical equipment dependable over the long term.
We work in San Antonio and communities throughout the broader Central Texas area. If we can service the site properly and stand behind the work, it’s in range.
We regularly step into systems with existing wells, pumps, and controls. We focus on understanding what’s there now and what it will take to make it more reliable.
Many San Antonio clients have staff on site. We typically handle deeper diagnostics, more complex repairs, and long-term system planning alongside their team.
We work across water and wastewater systems where wells, pumps, motors, controls, or monitoring equipment are involved.
We can add or refine monitoring, automation, and alerts so issues are easier to see and respond to before they turn into downtime.
Once we understand your equipment and usage, we can build a preventative maintenance plan for pumps, motors, tanks, controls, and related equipment that fits how your site actually runs.
