Some rainwater systems are designed to blend into the surroundings, while others are designed to make a statement. 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 of the Alterman campus is a CorGal 1506 flat-roof rainwater harvesting tank positioned above a dry riverbed on a custom concrete foundation. The foundation concrete was stamped with a custom CorGal panel, which provides a cohesive and unique look at the base of the tank.
One of the most distinctive features of this project is the custom roof extension, which adds more than 8 feet of additional galvanized steel above the original tank structure. That added height introduced significant structural demands, necessitating support beams extending from the upper enclosure into the concrete foundation below.
This project also required a custom funnel system to work with the extended enclosure. An aqueduct-style conveyance system channels rainwater and AC condensate from a nearby rooftop into the tank, helping maximize water capture.
Projects like this highlight the range of design and engineering considerations that go into custom water systems. Working closely with Rialto Architecture Firm, whose vision helped shape the project’s distinctive appearance and seamless integration into the Alterman campus, we developed a system that balances architectural impact with long-term performance. From structural considerations and water capture strategies to site integration, every detail was designed to deliver reliability, functionality, and a bold visual statement.
