Probably the best way to reduce the volume of water used per flush from a
holistic viewpoint is to consider the total volume of water used on a
visit. In general, for every flush of the toilet there is also a need for
hand washing, etc. One way of reducing the total water used, therefore,
would be to combine the functions of hand washing and flushing. In other
words, you use the water used for hand washing to flush the toilet.
