Water Resources

The Aqualiner® Advantage

The Aqualiner® is the best liner in the water tank industry, hands-down. Unlike the liners in most water tanks, the Aqualiner® is made from a reinforced fabric with a woven center layer for strength and durability.

Pioneer Water Tanks Aqualiner tank liner

Although the liner is hidden from sight and often doesn’t get noticed unless there is a problem, we feel that it is perhaps the most important part of the tank which is why only Aqualiner® membranes are used in Pioneer® tanks.

A clear polyethylene film coats both sides of the water tank liner, giving the product NSF 61 approval for the storage of drinking water. The Aqualiner® is well-known for not imparting any taste or smell in the water, so when the quality of your water is paramount, choose Aqualiner®.

Made with Zincalume® Steel with Activate ™ Technology

Only the highest quality Zincalume® and Colorbond® steel is used in Pioneer® Water Tanks, providing unmatched durability that no other tank manufacturer can offer- that’s why Pioneer® Tanks last longer than any other brand.

Next generation Zincalume® Steel’s patented Activate™ technology introduces magnesium into the aluminum-zinc alloy coating, improving galvanic protection by activating the aluminum. The result is a tougher protective coating that’s more resistant to scratches and scuffs encountered during construction. Proven to outlast galvanized tanks by 200%, according to BlueScope Steel studies, Pioneer Water Tanks are engineered to exceed. With a standard lifetime of 20 – 25 years, Pioneer Water Tanks include magnesium anodes that are buried underneath the tank to take on corrosion. When these magnesium anodes are replaced every 10 years, the protection continues as corrosion is kept away from the water supply.
