Abstract
Freshwater scarcity is becoming more imminent in the face of changing climate conditions, which put a lot of pressure on Dutch water systems. The river-dune drinking water system in South Holland is facing transformation to properly keep up with drinking water demands. And yet, coastal residents remain largely unaware of the dunes as the production landscape of their drinking water.
The aim of this thesis is to design a proposal for an adaptive water system, where coastal dwellers are included as participants of the system and stewards of the drinking water landscapes. The main research question is: How can landscape architectural strategies mediate a renewed relationship between contemporary coastal inhabitants and sources of freshwater within the drinking water extraction landscape of the Dutch dune system? The question is answered through systemic analysis, site visits with observations and design experimentation.
The research offers insight into the growing detachment between humans, landscape and infrastructure and how that detachment is now facilitating the effects of water scarcity to remain invisible. In order to include people in tackling the issue of water scarcity, a regional water strategy is developed where pressure on the dune landscape is relieved by separating water flows for potable and non-potable water. The result is a circular and adaptive drinking water system from Meijendel to the Vlietlanden. Furthermore, very explicit design interventions translate the water filtration processes spatially in order to facilitate renewed water relationality. Two design interventions translate valuable water filtration processes at the source and in the dunes, which offer interactions with their drinking water to coastal dwellers.
