Today, we’re highlighting a recent installation of a CorGal 405.5 rainwater tank at a residential property. This tank holds over 1,300 gallons of water and is primarily used for irrigation purposes. From the start of this project, we knew our tanks diameter would be the biggest limiting factor in creating a complete water system for this residence. Metal tanks rarely come in sizes compact enough for such restrictive areas, but we also knew they would provide the best long‑term performance.
Fortunately, our partners at Water Storage Tanks, Inc. worked closely with us to engineer a unique and custom tank that met the strict diameter requirements while still providing the storage volume the homeowner needed. The final result was a sleek, space‑efficient tank standing over 16 feet tall! This was a unique installation that both our team and the customer were thrilled to see come together.
Project Spotlight: Delivering Sustainable Water Solutions for DFW Airport’s ECUP Development
Advancing Sustainability at One of the World’s Busiest Airports
SWS is proud to highlight our recent contribution to the Dallas Fort Worth International Airport (DFW) as part of its groundbreaking Electric Central Utility Plant (ECUP) initiative. The ECUP development is a cornerstone of DFW’s mission to achieve Net Zero Carbon emissions by 2030, modernizing the airport’s heating and cooling infrastructure while dramatically improving efficiency and reducing environmental impact.
Our Solution: Customer Engineered CorGal Steel Tank
As a trusted partner in sustainable water systems, SWS collaborated closely with Water Storage Tanks, Inc. to design and deliver a CorGal 1509 Corrugated Rainwater Harvesting Tank customized with a flat roof to meet height restrictions. Powered by a duplex pump system, this tank collects rooftop rainwater and channels it into the ECUP facility, where it is reused within the airport’s heating and cooling processes.
Key Tank Features
Size & Scale: Standing at an impressive 32 feet tall, this tank provides substantial storage capacity while maintaining the sleek, modern profile CorGal systems are known for.
Duplex Pump: Ensures reliable, continuous delivery of captured rainwater into the ECUP system.
Optimized for Limited Space: Site constraints were one of the most challenging aspects of this installation. Working alongside Water Storage Tanks, Inc., SWS engineered a custom configuration that maximized storage within strict spatial limitations—without compromising aesthetics or performance.
Despite the tight installation footprint, our crew successfully stood the tank and pumps in under two weeks.
Supporting DFW’s Path to a Greener Future
Though the ECUP development is still underway, the rainwater harvesting system installed by SWS already plays a critical role in supporting DFW’s sustainability goals by:
Reducing potable water consumption
Lowering operational emissions
Improving long‑term energy resilience across the airport campus
This tank is more than an installation; it’s part of a transformational step toward a more efficient, environmentally responsible airport infrastructure.

Fire tanks are essential for development in locations that do not have reliable water sources. While smaller than most, this 0903 WT CHR CorGal fire tank serves a small office in Travis County. All fire tanks are engineered and designed the NFPA 22 and are built to the specifications required by the local authority having jurisdiction.
Rainwater harvesting and breweries go hand in hand in Austin, Texas. The CorGal 0802-WT-CHR will allow for 2,500 gallons of water storage and adds to the beautiful mural in the back.
The Luci and Ian Family Garden is a Sustainable Sites Initiative™ (SITES®) Pilot Project at the Lady Bird Johnson Wildflower Center. To inform children about water conservation and rainwater harvesting, the landscape architect designed an 8,000 gallon CorGal® inverted roof tank. This tank played an integral role in helping the LBJ Wildflower Center achieve that prestigious SITES® status, one of only 30 in the nation.
The tank sits between a solar-powered, wooden pavilion and a stone restroom building. Water is collected from both buildings’ roofs to replenish a creek, which houses fish, tadpoles, frogs and native water plants. The water tank also feeds the gorgeous waterfall display in the center of the garden. The Family Garden connects the younger generation with nature and promotes conservation.
Architects and engineers are capable of creating inspirational sustainable developments with CorGal® Tanks.
