Those corrugated grooves are not just for show. They’re integral to the performance of the small Promax ENDURO water tank, the strongest of its type in New Zealand.

The corrugated side walls add unrivalled strength and durability to this above-ground water tank; it’s strong enough to be partially buried and will provide years of maintenance-free water storage.

A small ENDURO is a perfect option if you require a compact tank for harvesting rainwater for your garden, beach, or pool or to top up your mains supply and reduce your water bills. It’s the premium model in our small tank range with many benefits.
