About the Summit

Sustainability. Scalability. Service.

The 2019 World Water-Tech Innovation Summit is where water utilities from all over the globe come to find solutions to today’s challenges of digitisation, security, energy recovery and new water resources.

Held in central London on February 26-27, 2019, this is the place to meet start-ups, tech giants, operators and investors.

The summit brings together 250+ water leaders for two days of collaboration, dialogue and deal-making. Networking is made easy, including advance connections with speakers and delegates via a 1:1 meeting system and a dedicated networking hub throughout the summit.

Each year the World Water-Tech Innovation Summit is produced in partnership with the UK Department for International Trade and attracts large delegations from Europe, Asia, North America, South America, the Middle East, Africa and Australasia who come to showcase best-in-class innovation and form lasting business partnerships.

This year we are also hosting an interactive business workshop focused on the question: How can we realistically work towards the ambitious target of zero leakage by 2030? This will be followed in the evening by the World Water-Tech Thames River Cruise. Open to all delegates, this informal networking event will feature a water-themed quiz and Classic British ‘Pub Grub’.
