Information about the two-year prescription

Prescription: when can it be requested

From 1 January 2020, the prescription period for water billing was reduced from 5 years to 2 years by the 2018 Budget Law (Law No. 205/2017), as modified by the 2020 Budget Law (Law No. 160/2019).

Final users included in the categories defined by the law and ARERA dispositions No. 547/19 and No. 610/21 can object to the payment of predated amounts included in water bills due after 1 January 2020.
