Durable, Worry-Free Water Storage for Homes, Farms, and Commercial Systems

Our corrugated steel rainwater tanks offer a long-lasting, low-maintenance solution for collecting and storing rainwater. Built from high-strength, G145 galvanized steel panels and equipped with a flexible, NSF/ANSI 61-certified polyethylene liner, these tanks are designed to perform in demanding conditions—without the upkeep required by other systems.

Why Choose Rainwater Storage Tanks?

G145 Galvanized Steel Panels
Our tanks feature corrugated steel panels with a 1.45 oz/ft² galvanized coating—offering superior corrosion resistance compared to Zincalume alternatives. While the tank is not independently rated for snow loads, a properly designed external support structure can be added to help manage snow accumulation and ensure long-term performance in snowy environments.

Set & Forget Reliability – 20-Year Warranty
With no sacrificial anodes to service and no ongoing maintenance required, our tanks are a true “set it and forget it” solution—backed by a 20-year no-service-costs warranty.

Potable-Grade Tank Liner
Each tank includes a solid polyethylene liner that is BPA-free, pesticide-free, and NSF/ANSI 61 certified for drinking water use. Its flexibility and strength ensure long-lasting performance and resistance to fatigue cracking.

Smart Rainwater Harvesting Options
Add a roof catchment system with optional gutter accessories to increase your collection area and maximize stored water. Whether you're irrigating, watering livestock, or supplying clean drinking water, these tanks are built to adapt.

Customizable for Your System

Depending on your end use, whether for irrigation or potable water, your rainwater system may include:

• Pre-filters and first flush diverters
