Rainwater
is a valuable natural resource that can be collected
for household use. Some benefits of rainwater harvesting
include :-
- reduction of mains water usage
and therefore reduction in water bills. You may be
eligible for a rebate on rainwater products from your
local water authority
- reduction in load on stormwater
systems as roof runoff is not flushed into the drains
- chlorine-free water for various
household uses
- collecting rainwater allows you
to be prepared for times of low rainfall, so you can
still maintain your garden, especially if there are
water restrictions in your area.
- reduces the need to build more
water storage dams, which may have to be situated
in environmentally sensitive areas.
'"If all
the homes connected to mains water around Australia
each had a 1,000 litre water tank, 5GL (5 Billion Litres)
of water would not have to be taken from the environment
every year" |

The most commonly used tanks in
urban areas for domestic use are made from polyethylene or
steel, which come in a wide range of colours and profiles.
There are a number of different acccessories, like pumps and
diverters, which can be added to the collection system to
improve quality and ease of use.

1mm of rain on every square meter of surface
area results in 1 litre of water into the tank. For
example if your house roof is 12 meters long by 10 meters
wide ie 12 x 10 = 120 square meters and you had a very brief
storm that dropped 1mm of rain on the roof, you would receive
1mm x 120 sq m = 120 litres of rainfall into the tank.
A larger storm comes through and drops 25mm of rain, 25mm
(of rain) x 120 (square meters of roof area) = 3,000 litres
of rainwater into your tank. This calculation
works for any roof area, all you need to know is the length
x the width = square meters.
