“Every dollar’s worth of fruit and vegetables has needed at least 103 litres of water to mature. Every equivalent dollar’s worth of home grown food uses only 20 litres”.
– David Holgrem
We purchased a three thousand litre plastic tank with the assistance of a government grant. It collects rainwater that runs off of our one car colourbond garage.
Fortunately we are allowed to use the rainwater as we choose, and it’s the main source of water for the vegetables and fruit trees. Our tank is situated close to the beds and trees, so we have managed to do without a water pump. Gravity works well until the tank is below a third full, then the pressure seems to drop off and watering takes twice as long. So far the tank has been big enough.
Natural rainfall always gives our plants a big boost in growth.
