Next: see how
much water you can replace with a rain water |
Now: see how
much water you can harvest with different sizes of rain
tank |
What area of the
roof will be connected to the tank (square metres) |
|
How big a tank would
you like to install (between 1 and 15 kilolitres)? |
|
What will you use
the water for? |
Toilet flushing? |
|
|
|
|
Laundry cold water? |
|
|
|
|
|
|
|
|
|
|
To meet these uses you would need this much water per year ... |
|
Your tank will provide you with this much water each year |
|
If you connect your entire roof
the maximum amount of water you could harvest each year
is |
|
But, each year this much will overflow because
your tank is already full (a bigger tank would harvest
more water) |
