CAPTURE SUFFICIENT RAINWATER FOR YOUR NEEDS

To determine the appropriate rainwater harvesting system for your requirements, use the following formula:

Roof area (footprint) in square metres x annual rainfall in cubic metres.

(650ml = 0.65m3), divided by 12 = average monthly rainfall capture.

e.g. 450m2 x 650ml = 292.5 (m3), divided by 12 = 24.375 or 24,375 litres per month average.

We recommend storing an average of two to three months’ worth of rainfall (bear in mind you may get three months’ worth in your wettest month).  In the above example you would require 3 x 25,000L tanks in series.

BOOST YOUR SUSTAINABILITY!

Cut your water bill and reduce your environmental impact by intergrating an Enduramaxx rainwater storage tank to capture and store the run off from your roof to make the most of this precious resource.

HOW CLEAN IS THE WATER?

To remove particles and other matter, rainwater is filtered when entering your storage tank. It is kept in the dark and oxygenated to discourage algal growth. Inbuilt calming inlets ensure that any sediment at the bottom of the tank does not get stirred up. NOTE: Without treatment rainwater is not fit for human consumption.
