Specified Water Systems Specified Water Systems is an authorized dealer for high-quality commercial and residential water storage tanks, including CorGal® Tanks and TimberTanks®.

Specified Water Systems, LLC is an authorized dealer for high-quality commercial and residential water storage tanks, including CorGal® Tanks and TimberTanks®, in the Central Texas market. While TimberTanks conjure images of old world charm, it is our CorGal line of galvanized steel tanks that has set the standard in the industry. CorGal tanks are engineered for longevity and have been successfully utilized for traditional rainwater collection, fire protection, storm water retention, mining applications, and winery/agricultural use. Very few water storage tank and rainwater harvesting companies have withstood the test of time. However, the team at SWS has been serving Central Texas for over ten years! With more than 600 water tanks installed throughout our community, most in very prominent areas, we have been trusted to provide a product that our customers can be proud of. Furthermore, CorGal® Tanks and TimberTanks® are manufactured right here in Central Texas. So we have unprecedented access to the resources required to custom engineer your perfect tank.

KXAN recently took a closer look at the rainwater system at the Campsite at Shield Ranch and the work that went into becoming Texas’ first public water system supplied entirely by rainwater.

We were fortunate to play a small part in that story, supplying several tanks used throughout the system for rainwater collection and storage.

Projects like this are a great example of what rainwater harvesting can look like when it’s considered as part of the infrastructure from the very beginning.

Definitely worth a read!

We're excited to showcase this custom rainwater harvesting project for Alterman, Inc.!

This installation is a prime example of a rainwater harvesting system that elevates everything it touches. Featuring a custom roof extension, aqueduct-style water conveyance system, and custom-engineered structural supports, it came together as a truly one-of-a-kind project we'll be talking about for years to come.

A big shoutout to Rialto Studio, Inc. and all of the incredible collaborators who helped bring this vision to life.

This custom rainwater tank for Alterman Electrical in San Antonio is a great example of a project that delivers a bold visual presence without sacrificing functionality. At the center o...

Project Spotlight: Electric Central Utility Plant at DFW Airport ✈️💧

We’re proud to support DFW Airport’s journey to Net Zero Carbon by 2030 with a custom rainwater harvesting system designed for the new Electric Central Utility Plant (ECUP).

We engineered and installed a 32‑ft‑tall CorGal tank with a custom flat roof and duplex pump system—built to fit tight site constraints while maximizing performance. This system is already helping DFW reduce potable water use, lower emissions, and boost long‑term energy resilience.

We’ve been told our tanks are sexy… and honestly? We see it.
Those corrugations. That capacity. That commitment. 😏
This Valentine’s Day, give the gift of Water Filled Love — and a tank that’s built for the long haul.
Because nothing says “forever” like reliability. ❤️

👀Ever wonder what the inside of a water tank looks like? Well, today’s your lucky day.

Our crew captured a short time-lapse while hanging the liner on a tank in the DFW area, and trust us, it was no small feat.

This is just a sneak preview of one of our favorite projects from the past year. We’ll be sharing the full story behind this mystery tank and how we installed it in the coming weeks. 🕧
