As of 2023, the abstraction of desalinated water for public supply in Italy stood at a consistent value of 0.06 cubic meters per capita. From 2024 to 2028, this forecasted value remains unchanged at 0.06, indicating stability with no year-on-year variation or compound annual growth rate (CAGR) in desalinated water use for public supplies. This steadiness reflects a period of equilibrium in the adoption of desalinated water within the Italian public water supply sector.

Future trends to watch for in Italy's public water supply include:

Possible technological advancements that might increase desalination efficiency.
Changes in policy or economic conditions that could affect the uptake of desalination technologies.
Environmental factors such as droughts or water scarcity that may necessitate increased reliance on desalination.
