Rainwater Collection Tanks
Aquamate is a leading supplier of large rainwater collection tanks, working with rainwater harvesting professionals to supply durable, reliable and affordable solutions for rainwater storage. No matter what your intended use is, you’ll need a rainwater collection tank to store the rainwater you’ve collected. What you plan on doing with the water after it’s stored will influence your needs. For simple irrigation systems, all you may need is a pre-filter, first flush diverter, and a small pump. For more complex drinking water systems, you may need to consider pumps, pipework, filtration and sterilization systems. Aquamate steel water tanks use a heavy duty galvanized coating on its steel tank shells, in combination with a flexible monofilament polyethylene liner, to provide a durable solution for rainwater storage.

Galvanized Steel Cistern
Lightweight steel panels and heavy duty galvanizing make Aquamate’s large steel water tank shells perfectly suited for water storage. Aquamate’s tank panels are covered with a galvanized coating that’s 1.45 ounces per square foot (G145) – the thickest advertised coating on the market. By using lightweight thin-gauge steel panels, Aquamate’s steel water tanks have all of the required strength to resist water, snow and seismic loads without the excess material cost.

20 Year “No Service Costs” Warranty
Aquamate’s ‘No Service Costs’ Pro-Rata Warranty leads the industry and is supported by over 30 years of experience choosing the correct materials to survive the toughest conditions.

Flexible Polyethylene Tank Liner
We use a BPA and pesticide free, solid food grade tank liner suitable for potable water use and certified to ‘NSF/ANSI 61:Drinking Water System Components – Health Effects’, as opposed to a coated mesh, because a solid liner is resistant to fatigue cracking and super stretchy – important characteristics needed for a durable steel water tank.
