Nevertheless, if it is important to run a system well it is even more critical to maintain it properly. As a result of the considerable growth of many cities, a good deal of the pipes in the water distribution networks are insufficient and in many cases old. For this reason maintenance and renovation is not only an important matter – it is rather a vital question.

This line is currently expanding at the ITA. The constant increase in citizens’ standard of living (which forces standards to rise) and climate changes are additional reasons for rationalising as far as possible the use of the two most valuable natural resources – water and energy.
