Water bills in Naples are set to rise slightly in 2027 following a tariff adjustment by ABC Napoli, the company that manages the city's integrated water service.
For a typical three-person household using 182 cubic metres per year, the annual bill is expected to increase by about 11 euros, equivalent to 0.92 euros per month. Annual spending for that sample household would rise from approximately 280 euros in 2026 to 291 euros in 2027.
The increase was scaled back after a tariff review by the Ente Idrico Campano on 30 October 2026. The planned 2027 adjustment was reduced from around 8 percent to around 5 percent, with part of the additional recognised costs postponed for recovery to 2028 rather than charged in 2027.
ABC Napoli linked the adjustment to its ongoing investment programme. The company reported more than 45 million euros in investments during 2025, against approximately 19.5 million euros in contributions received.
A further investment programme of approximately 69 million euros is planned for 2026-2027, including 38 million euros in 2026 and 31 million euros in 2027.
The 11-euro figure is a sample calculation and may differ for households with different sizes or consumption levels. A complete 2027 tariff schedule for every household type was not included in the available report.
