Water Discovery Challenge

The Water Discovery Challenge (Discovery) aims to accelerate the discovery, development and implementation of promising, early-stage innovations by the water sector. By providing funding, mentorship and expert support to organisations from outside the sector, it aims to create a pathway for disruptive innovations to be developed, implemented and scaled in the water sector. 

Discovery 2 launched in January 2026 and closes 8 April 1pm (GMT). We expect Discovery 2 to run in a similar manner to Discovery 1, with approximately £7.5m available over a Finalist and Winner phase; as well as a tailored package of non-financial support designed to help innovators understand the water sector, develop their solutions, and attract the investment and support they need to succeed.
