Water wheels

摘要

Throughout 2006 Jacob Tompkins from the water body Waterwise will be trying to get a better deal for people buying wheel-washers, - well at least those products that have some form of water recycling system attached. Wheel-washers are thirsty machines. An average model can use around 3,000 litres a minute and such usage does not sit comfortably with water companies as there is not enough of their product to go around.
