Cel The aim of the project is to demonstrate successfully surface infiltration in a river landscape with clay and peat soils in the basin of the Meuse. Foreseen results include insight in infiltration behaviour, spread in detention times, spread in infiltration velocity, developments in water quality and the effects of land and water management surrounding the infiltration system. The results will be disseminated in the Netherlands, Belgium, Germany and France.Desiccation of nature resources is an important bordercrossing problem in The Netherlands and surrounding contries. The European Union and national and regional authorities have developed policies to combat desiccation. As a result of national policies the share of groundwater as a source for public water supply has to be reduced from 66 to 50 percent. Therefore, the NV Waterleidingmaatschappij Oost-Brabant (WOB) has to use more surface water for public water supply in the future. The current techniques for the direct use of surface water entail considerable disadvantages like energy use, negative environmental effects, the use of space and costs. Surface infiltration appears to be an environmentally sound and innovative groundwater saving technique as compared to other techniques. With this technique pretreated surface water is infiltrated in the underground, pumped up after a certain detention time and made suitable for usage as drinking water is infiltrated in the underground, pumped up after a certain time and made suitable for usage as drinking water by a limited post-treatment. The detention of water in the underground provides for desinfection, a constant quality, biological stability and calamity protection. Besides, the underground serves as a depository by which peaks in demand and peaks in the surface water quality parameters, can be levelled out. In The Netherlands surface infiltration has been applied only on sand grounds (dunes). Large parts of The Netherlands and surrounding countries have another geohydrologic soil composition (peat, clay) and shallow groundwater levels. These circumstances are considered difficult for the application of surface infiltration. The WOB has developed a new application of surface infiltration for such circumstances and intends to demonstrate surface infiltration in a large scale public water supply project with an ultimate capacity of 50 min m{3} annually. The entire project consists of an intake reservoir, pre-treatment works, a surface infiltration system and post-treatment works. The project is situated in the basin of the Meuse near the village of Lith. An essential part of the surface infiltration system is isolation of the system underground from the surrounding undergrounds including the Meuse. By means of a smart integrated groundwater management system processes in the underground are managed in such a way that outside the infiltration system the ground and groundwater are not influenced (desiccation, sagging). In and around the infiltration system the nature is developed actively and agricultural areas will be conversed in nature. Thus, the project can be considered an innovative groundwater saving application that fits in and even is an enrichment of the surrounding nature and landscape surrounding. Initially, in the demonstration project an infiltration system will be built. In a demonstration period of 2 years the working of the system will be monitored, verified and, if necessary, futher optimized. As still uncertain technical and financial aspects factors, the demonstration period will be used to collect more knowledge on these factors. After successful demonstration considerable possibilities for application exist in The Netherlands, Belgium, Germany and France. In Belgium the 'Vlaamse Maatschappij voor Watervoorziening' and the 'Provinciale en Intercommunale Drinkwatermaatschappij der Provincie Antwerpen' intend to apply the demonstration results in their own projects and will follow the project from near in an application group.
