GO-Fresh II

Large parts of the Southwest Delta of the Netherlands have no external fresh water supply. These areas are forced to rely on fresh groundwater that is available in dunes, creek ridges and thin lenses of rainwater that gather in the polders. As a result, freshwater availability in the root zone of these areas depends on surplus precipitation and groundwater supply. For this reason, these areas are vulnerable in times of dry weather, which are likely to increase in the future.

In order to tackle this vulnerability, a selection of local measures have been developed to store excess freshwater in wet periods with the aim of using it again at a later stage during a dry period. The goal is to make these areas in the Southwest Delta more independent and less impacted by weather.

The GO-Fresh research project was launched in 2012 under the Knowledge for Climate program with the aim of increasing freshwater availability at three different locations. GO-Fresh II is the second stage of this project which will aim to elaborate further on the solutions tested in GO-Fresh, leading to a robust freshwater supply on a local scale. The economic and social feasibility of each solution will also be investigated during GO-Fresh II.

The Water Technology Research Group has developed a wiki for GO-Fresh II, wherein all pilot results are represented. The end goal for the research group is to provide a publicly available decision tool to help local land owners determine if any of the technical solutions are feasible for their land.
Consortium partners that the Water Technology Research Group are working with on GO-Fresh II include: Deltares, KWR Water Research, Alterra, Acacia Water, ZLTO.
