Business
The private water sector is larger than many
people think, with thousands of businesses
working every day, for the most part, to
implement government policies.
This fact has been understood in China, where
the central government decided to increase the
water rates in most large cities a few years ago
in order to finance investment program

Educate to prevent
In Britain, drinking water is available to pupils
throughout the day. Studies have been made
upon the effect of increasing the provision
of water in school and significant
improvements in test scores have been
observed.
