An SWS solution gives you the power to create the water storage system that’s right for you. We offer diverse options to meet the requirements of any site.
A range of applications
SWS tanks can be designed for rainwater harvesting (including irrigation and potable water storage), fire protection, and stormwater management, to start. We also adapt our tanks for special projects, such as signage or shelters.
Many sizes available
Tanks with roofs can be built from 4 feet to 120 feet in diameter; tanks without roofs can be up to 200 feet in diameter. With heights ranging from 4 to 30 feet, an SWS tank can hold anywhere from 320 to more than 500,000 gallons of water.
Customizable roof options
Our tanks can be designed with pitched, flat, or inverted roofs, to fit your functional needs. Available roof options include:
- 30° Flat-Seam Roof Panels for 6 ft., 8 ft., and 9 ft. diameter tanks
- 10° High-Rib Roof Panels on 6 ft. to 72 ft. diameter tanks
- 30° High-Rib Roof Panels on 6 ft. to 120 ft. diameter tanks
- Flat Roofs on 4 ft. to 27 ft. diameter tanks
- Inverted Roofs (also known as Funnel Roofs) on 6 ft. to 18 ft. diameter tanks
Versatile exteriors
Exteriors can be galvanized steel, timber, painted, or clad. Some customers use our tanks as beautiful and distinctive signs. Our goal is to always create the solution that best meets your needs.
Engineered to last
Every CorGal® corrugated, galvanized steel tank will be engineered to meet IBC 2013 standards with the option to upgrade based on site specific requirements or customer preference. We offer a thorough, site-specific structural design calculation package, which is developed and stamped by a licensed engineer, as an option on every CorGal Tanks project. This important engineering package ensures the tank is built to the location’s requirements by taking numerous calculations into account, such as wind and snow loads plus seismic activity. Every tank includes a geotextile preliner and a flexible membrane liner, which prevent corrosion by keeping water away from the steel interior of the tank to prolong the product’s lifespan. Concrete foundations are necessary to stabilize the tank position and limit movement in the event of extreme weather or natural disaster. Tanks can also be constructed on a tower or other elevated location if gravity flow or high visibility are desired.
Fast and economical
SWS tanks are built on location, more quickly and at a fraction of the cost of old-fashioned bolted or welded steel tanks. Because each tank arrives unassembled, it can be erected on difficult-to-access project sites. It can also be disassembled and relocated, if necessary.
A secure investment
SWS tanks have an expected lifespan of 50+ years. Our tanks are always protected under a 10 year structural warranty. Each liner has its own individual warranty, ranging from 5 to 12 years.
