The only filter used is a simple wire mesh to keep remove any leaves. snails etc that may have been washed into the tank. > Does the tank cover the whole roof?

The tank is freestanding about 5m from the house so cannot be used for thermal insulation. The water downpipes from the roof are simply emptied into the tank. A pressure pump then reticulates the water to the house. This is the common method used in Australia outside the cities and towns. In fact, in many towns, people install small rainwater tanks for drinking water, rather than drink the treated town water. Bore water is generally not used for domestic purposes. _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
