Sustainability – according to one of the most widely accepted definitions, that of the Brundtland Report,  means “development that meets the needs of the present without compromising the ability of future generations to meet their own needs”.

In recent years, with the parallel development of environmental awareness and the information society, the knowledge that not only our interest “as a species”, but also individual and immediate interest is inextricably linked with the natural equilibrium is gradually being confirmed. From this point of view, sustainability can simply be defined as a search for the natural equilibrium.

This is also valid for the design and management of the Integrated Water Service understood as the collection of activities related to the construction and management of mains water and sewerage-purification systems.

In this sense, the main themes regarding sustainability under the scope of the Integrated Water Service all revolve around the efficient use of water resources with regard to natural equilibriums.

Schematically, the main activities on which special attention must be focused in terms of “sustainability” are:

  • the need to minimise the impact on the water bodies used, with special reference to compliance with the minimum environmental flows of superficial watercourses and compliance with underground aquifer refilling dynamics in order to prevent subsidence;

  • the need to reduce leaks to prevent unnecessary collection from sources and energy dissipation;

  • The need to guarantee adequate treatment of waste waters before they are reintroduced into the natural cycle in order not to compromise the quality of the receiving water bodies.
