. The government's policy concerning the management of the dunes in the Netherlands on behalf of the interests of nature and environment is causing constraints for the waterworks of North‐Holland located in the dunes at the North Sea coast. The existing artificial recharge systems consist mostly of ponds and open canals in which imported pretreated surface water is infiltrated to provide a reliable drinking‐water supply in the province of North‐Holland. Because the quality of the water, which is infiltrated by canals, has a negative influence on ecological values, the extension of this system will not be possible anymore. Many experiments in the past were done to provide a substitute with as good a performance for the drinking‐water supply as the shallow infiltration systems but without negative impacts on nature. One of these alternatives is deep‐well infiltration: instead of infiltrating by canals, water will be infiltrated in semiconfined aquifers, so there will be less influence on existing ecological values. The Provincial Waterworks of North‐Holland are constructing a pilot plant with a capacity of 5 million m 3 /a (a = per year) to investigate its reliability and its suitability for a development as natural as possible of this region. This paper gives the history which has led to this new system of artificial recharge, an overall look at the preliminary investigations, and finally an overview of the main issues for the definite engineering.
