GO-FRESH: Geohydrological Opportunities FRESH water supply

Posted on 15 August 2014


In the SW delta of the Netherlands, the agricultural sector is confronted with growing impacts of water shortage and salinization. Farmers and government are aware of the negative influence on the development of the agricultural sector.

A reliable freshwater supply is considered as one of the key issues for future development and sustainable growth. Improving the use of existing fresh groundwater resources and create new freshwater reserves by several methods is quite innovative and could be promising in other delta’s in the world, where fresh water is becoming scarce. If the technology can be proven to be sound, possibilities for upscaling worldwide (Nile, Mekong, vulnerable islands) will be considered.

Promising technologies:

  • Showcase ‘The Freshmaker’; aquifer storage and recovery (ASR) utilizing the potential of sandy creek ridges for water storage
  • Showcase ‘Creek Ridge Infiltration Test’; infiltration via drainage utilizing the potential of sandy creek ridges for water storage
  • Showcase ‘Drains2Buffer’; optimizing the freshwater volume in shallow rainwater lenses

Project partners

The province of Zeeland, ZLTO, the Water Boards Scheldestromen and Brabantse Delta, the municipality Schouwen-Duiveland and STOWA all contribute to the project, from a financial contribution to inserting local expertise, arranging permits and taking care of small water management


  • To improve the use of existing fresh groundwater resources and create new freshwater reserves, thereby increasing regional self-sufficiency 
  • Reducing dependence on external freshwater supply

Research already takes place on theoretical feasibility of possible measures. Building on this knowledge, the research goals are:

  • To investigate which measures actually ‘work’ in practice
  • To analyse whether such measures are economically feasible.
