The value of water as a resource has now been recognized on a global scale, albeit with different levels of awareness due to its availability and accessibility. All western countries have regulated the management sector of this resource (Integrated Water System – SII), regarding both its distribution as well as the purification and collection of sewage waste. Italy has also moved towards privatizing its management, proposing a collaborative mechanism between the public regulatory Authority and the private operator. The investments for the maintenance and development of the asset are therefore supported by the private investors. The model proposed in this work is based on the use of AHP to encourage the conciliation of opposing interests and rationalize a rather complex regulatory phase. It facilitates the selection of technical investment alternatives for the improvement of the SII supply standards.
