Tap Water
In most developed nations drinking water is piped to homes and is available on
tap. Usually it is safe water. The provision of tap water requires a massive infrastructure of piping, pumps,
and water purification works. The cost of tap water is a small fraction of that
of bottled water, often as little as a ten-thousandth.
The same water supply that is used for drinking is also used for washing,
flushing water closets (toilets), washing machines, and dishwashers.
Experimental attempts have been made to introduce non-potable greywater or
rainwater for these secondary uses.
In many areas, fluorine is added to the tap water as a means to improve public
dental health. This remains a controversial issue in terms of the health,
freedoms and rights of the individual.
The availability of clean tap water brings major public health benefits.
Usually, the same administration that provides tap water is also responsible for
the removal and treatment before discharge or reclamation of wastewater.
