| Low coastal areas like the Netherlands and Belgium experience salt water intrusion and therefore limited sources of fresh water. In the south-western region of the Netherlands fresh water is obtained from the Biesbosch basins, which are located at least 100 km from the consumers. These consumers are industry, households and agriculture/livestock. With increasing fluctuations in precipitation and (likely) sea level rise, this fresh water stress is very likely to increase in the (near) future. In order to decrease the dependence on remote fresh water sources, and thus increase local resilience, precipitation should be better collected and preserved, instead of immediate discharge to the (saline) sea, which is currently done to prevent flooding. Integrating fresh water storage and supply with spatial planning, while maintaining or even upgrading the water quality, benefitting all stakeholders is the challenge for current and future delta developments. | | Low coastal areas like the Netherlands and Belgium experience salt water intrusion and therefore limited sources of fresh water.

| | Project Robust Water System aims to increase the resilience of the Zeeuws-Vlaanderen region by incorporating water multi-sourcing and ‘fit for use’ strategies. These strategies require close collaborations with stakeholders (end-users, government, research). Water sources are expanded towards Belgian polder run-off, municipal WWTP effluent, Dow WWTP effluent and rainwater. Agriculture is using polder run-off and potable water but do experience fresh water scarcity during periods of severe drought. Nature areas suffer from drought periods – overall there is a lack of salt nature. |

Fresh water availability, supply and buffering in a saline environment, with increasing fresh water stress.

| Fresh water availability | 1 januari 2018 | | This projects contributes to integrating fresh water storage and supply in spatial planning, while maintaining or even upgrading the water quality, benefitting all stakeholders. Phases of this (larger) project B, divided into sub-projects C: Initiating: Braakman Zuid possibilities; Proposed: reuse surface water with wetlands; Execution: mild desalination, enhanced reuse; Finalised: desalination of seawater (not feasible) |
| Impact project Spatial Adaptation Robust Water System Zeeuws Vlaanderen | 1 juni 2016 | 30 november 2016 | The aim of this project was to positively contribute to the cooperation of participating parties and capturing and sharing their knowledge and experience. The knowledge will be shared in the form of a wiki, developed by the HZ University of Applied Sciences. The wiki is a tool that will detect the interrelationships between the various initiatives within the robust water system, with the aim of strengthening collaboration of existing parties and stimulating new parties to participate.

| Living Lab Fresh Water E4 (Proeftuin Zoet Water E4) | 1 januari 2015 | 31 maart 2017 | Fresh water availability can be increased by mild desalination brackish water sources. Demonstrating that desalination is a viable option was proven in the E4Water project (http://www.e4water.eu). The brackish water source, however, comes with variable flows and quality and could be buffered and treated in a constructed wetland in order to remove suspended solids and phosphorous. This project investigated the feasibility of such constructed wetland. In order to provide 10,000 m3 per day a wetland of 12 ha was proposed, which could produce at least 85% of the required fresh water. Additional benefits associated with the wetland, like tourism or changing water intake by local farmers, were negligible. The cost of such infrastructure is substantial, an estimated 4.1 MEuro. Answering the question whether this investment is acceptable with respect to the mitigated risk of water not being available was not part of this assessement. |
