About this event

H2O Accadueo is the only international trade fair in Italy dedicated exclusively to the civil and industrial water sector. The 21st edition returns to BolognaFiere (the show alternates between Bologna and Bari) and brings together water utilities, technology suppliers, engineering firms and industrial water users to look at the whole water cycle, from abstraction and treatment to distribution, reuse and the digital management of networks.

What's on show

Exhibitors and conference sessions focus on the technologies and rules that shape the water cycle. - Water and wastewater treatment for civil and industrial uses - Water reuse and resource sustainability - Digitalisation: smart water management, AI, IoT and big data, smart metering - Leak detection and reduction of network losses - Regulation and compliance for utilities and industry

Co-located with International NO-DIG

H2O runs at the same time as the 43rd International NO-DIG, the annual global event on trenchless technology for underground utility networks. The International Society for Trenchless Technology (ISTT) assigned the 2027 organisation in Italy to the Italian Association for Trenchless Technology (IATT), linking water-cycle innovation with the construction and rehabilitation of the pipes that carry it.

How to visit

Access to the fair is free after registration, which is completed exclusively online through the official website. The event is aimed at water utilities and multi-utilities, public administrations, design and engineering firms, installers, industrial plant managers and researchers.
