STANDARD INCLUSIONS
AQUALINER® FRESH
The first antimicrobial tank liner in the world, our exclusive five-layer AQUALINER® Fresh keeps your water fresher for longer with embedded Sanitized® Silver technology. With a life expectancy of 65 years, the AQUALINER® Fresh is designed to fit the Pioneer Water Tank to prevent contamination.
GEOTEXTILE UNDERLAY
Our geotextile underlay is the ideal way to protect your AQUALINER® Fresh from being compromised by sharp objects that may be caught inside your water tank.
SUPER SEAL
Reduce the number of contaminants to protect your precious water supply with Pioneer Water Tanks’ high-density foam sealer.
SACRIFICIAL ANODES
Our sacrificial magnesium anodes significantly extend the life of your water tank by protecting the tank from corrosion. Made from magnesium, the anodes erode in place of the water tank, thereby protecting the steel and allowing the tank to last longer than other systems. Pioneer Water Tanks recommend your anodes be replaced every 10 years so you can enjoy the benefits of your tank for life.
6-INCH DIAMETER OVERFLOW
Pioneer Water Tanks provides a 6” diameter overflow downpipe, the largest overflow system on the market. The overflow size moves excess water away from the tank quickly to effectively reduce pressure on your tank and avoid costly damage to your tank components.

WORLD-FIRST ANTIMICROBIAL WATER TANK LINER
The multi-generational AQUALINER® Fresh fabric has been a mainstay of the Pioneer Water Tanks 30-year success story and legendary water-holding performance. The new fabric retains the Globally Patented Multi-layered PP/PE textile with a spun-woven multifilament polypropylene (PP) scrim construction (WO 2007/070917).
The use of antimicrobial protection in a tank liner is the world’s first use of this technology in this application, and our Australian manufacturer of the fabric has applied for an additional Patent to protect this innovation. The patent application has been accepted and its current status is “Patent Pending 2017902908”.

Pioneer Water Tanks, AQUALINER® Fresh antimicrobial tank liner is a world’s first to keep your water fresher, for longer.
The AQUALINER® Fresh is manufactured utilizing a patented three-layer process that adheres a PP Multifilament Base with a Polyethylene Film on the surface.
The PP base, PP/PE Coating, and PE Film are all bound together through a process called Extrusion Coating.
The PP Multifilament Base provides strength, flexibility, and dimensional stability.
The PE Film provides toughness, water-resistance, and heat seal characteristics.
“The AQUALINER® Fresh tank liner is the culmination of Pioneer’s 30 years’ local and international experience in water storage and a result of our continuous drive to improve the way we store water for the benefit of our customers. Water quality is an important global issue and we know it’s one of the most important factors people consider when buying a water tank” said Daniel Wyatt, General Manager, Pioneer Water Tanks.
