SPONGE2020 is a project partnership between Dutch, British and Flemish local government and water authorities to co-create and implement innovative climate change adaptation solutions, such as Sustainable Urban Drainage (SuDS) with local stakeholders.

SPONGE2020 paves the way for a wide rollout of these solutions to reduce the risks of and damage from urban flooding across the 2 Seas areas, the coastal regions along the Southern North Sea and the Channel, at considerably lower costs.
