Product Description

SORRY - this deal is an Auckland-only deal and is delivery only. No pick-ups.*

"The Auckland region is still feeling the effects of a severe drought which took hold in 2019 and saw our total water storage (all our dams combined) drop to the mid-40 per cent mark. While recent rain has helped replenish our dams, much more is needed."  ~ Source:, 30 September 2020.

In any drought situation, a new "Urban" Water Tank could be your new best friend! The Promax 4000L Water Tank with Pump is perfect for collecting precious rainwater during wet spells to save for dry periods. 

The collected water can be useful for many areas including the garden, pool, beach house or for  topping-up your main water supply.  And obsessive car-groomers will be able to keep their babies looking mint.

These Promax Water Tanks have corrugated side-walls so these units  are strong, durable and will provide maintenance-free rain water collection for many years to come. Connecting the tank to your down-pipe is a simple task,  we recommend talking to your local plumber or if you're DIY-savvy you can give it a go yourself.
