Did you know?

MERCER CONTROLS is now in the Chlorination Business! For more information, please check out our bulletin. Thanks!






































We started our business to provide high-quality custom control panels. We are proud to say that the industry has responded enthusiastically to our product. Our panels are dependable and they are easily serviced by local electricians with local parts. Our panels "work...and keep on working!"

There is an art to water and wastewater management that few people see, and even fewer people understand. At Mercer Controls, we like to help bridge that gap by bringing our clients closer to the source of the problem, while diagnosing the perfect solution.

Originally based out of Edna, TX, Mercer Controls has been able to grow over the course of two decades into what it is today. We proudly service Houston, San Antonio and other surrounding cities, making Mercer Controls an unforgettable name across the board.

When it comes to control panel manufacturing, we’ve got our products down to such a science. However, few people realize the same can be said for our telemetry systems and chlorination equipment. Since 1992, Mercer Controls has made it our mission to serve countless numbers of water and wastewater industries, which is why we’ve worked to diversify our services to fit everything you’ll ever need.

Below, you’ll find in-depth descriptions regarding our control panels, chlorination equipment and telemetry systems. We can proudly assist you if you have any additional questions, but we hope you will find the following reviews very useful in your search.

In addition to your control panel specialist, Mercer Controls also wants to be your chlorination supplier. That starts with knowing that products from SUPERIOR™ are simply better. Major parts have a lifetime or a three-year warranty. In fact, all SUPERIOR™ vacuum regulators, remote meter panels, ejectors and automatic switchover modules are hand-assembled and tested to rigid standards. They are fully compatible with most other chlorination systems. One or more of these SUPERIOR™ assemblies may be used as replacement or upgrade components or other brands, usually at significant cost savings. And SUPERIOR™ assemblies are just that...superior to virtually all original equipment components.

Let us help you with the installation of your Water and/or Wastewater telemetry system equipment. Water and wastewater systems usually rely on telemetry, which is the monitoring of remote locations.

Implementing water telemetry reliably is a complex subject because communications must be dependable, and all of the logic for the water network has to take into account those times when communications are not operating correctly.

Telemetry Equipment we can provide: Radios, Transducers, PLCs, Modems, Antennas, Surge Protection, Lighting Arrestors, and various modules.
