Every
time it rains, water droplets from tiny particles of matter known
as condensation nuclei. Such nuclei consist of dust, salt
from the ocean spray, and chemicals. Some of these chemicals
form when gasses in the air react with each other, while the others
are given off by industrial plants and motor vehicles. The
first portion of water droplets clean the air by absorbing dust
and chemical particles on their journey to earth..... (
You may have noticed that the air is clearer and fresher after
a rainfall ). The initial rainfall also clears pollutants
from roofs and gutters. Raincatcher's filtration
system diverts the tainted water away, ensuring only the clean
rainwater enters the drinking water supply.
How is this done?
|
|
|
|
|
|
|
The
rainwater runs through a stainless steel sieve which eliminates leaves,
etc, and from there flows into the dump tank. This tank holds the initial
rainwater which may be tainted by dissolved material from the guttering.
This unclean water slowly filters out into an overflow pipe and then
into your down pipe. |

|
When
the dump tank is full the remainder of the rainfall gets diverted into
the main body of the tank, which stores 230 litres. This is the cleanest
water abtainable from the rainfall. Every new rainfall continues through
the filtration cycle, and then enters and circulates with the stored water. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The
main body is fitted with an overflow outlet at the 230 litre level,
to enable excess water to discharge through the overflow pipe, and disperse
to your storm water down pipe. This process ensures the drinking water
remains fresh. |
|
|
|
|
|
Not
every rainfall will help fill the main storage section, on days with only
the occasional drizzle there would not be enough consistent rainfall to
keep the dump tank full. However, even this is beneficial as it helps
dispose of roof contaminants and assists with keeping the guttering clean
and ready for the ensuing rainfall. |
