The most basic form of
rainwater harvesting is the collection of rainwater for the watering of
your outdoor plants. Many municipalities are encouraging the collection
of rainwater for this purpose. Since rain water doesn’t undergo any
water treatment it conserves our valuable drinking water, lowers your
water bill and lowers the cost of community water treatment (33% of the
City of Toronto's electricity use in a year is spent on water pumping
and treatment).
There are many sources for rain barrels that are designed specifically for this purpose.
Once set up, you may never need to pick up your watering can again!
Don't worry if your rain barrel isn't in a sunny location. The maximum
run of tubing can be 60 meters and the pump can be located up to 20
meters away from the rain barrel.
