"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: watercare.co.nz, 30 September 2020

In any drought situation, a new "Urban" Water Tank could be your new best friend! The Promax 4000L Water Tank with Fitting Kit 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.
