Watershare is an international water-sector partnership model, in which experts from leading institutes share their knowledge and skills, and pack them into practical tools which are then applied to projects in water practice. In the Communities of Practice (CoPs) Watershare members work together on the development of best practices to meet global water challenges.

The Subsurface Water Solutions (SWS) CoP builds on the experience with Managed Aquifer Recharge and Aquifer Storage and Recovery. Thanks to innovations in well design and groundwater modelling and management, SWS are now widely applicable. Take, for instance, Freshkeeper, which deals with the salinisation of aquifers and water wells, and ASR Coastal, for the storage of freshwater in brackish aquifers. SWS open news perspectives for water management in coastal areas in the shape of practical solutions for water issues confronting farmers, water companies, industry and cities.
