On this platform I am gathering knowledge from the present and the past. From the ancient stepwell water temples of India and the Venetian rainwater harvesting squares to today’s number 1 waste water recycler Singapore.
More specifically The Thirsty City projects looks at freshwater supply from three perspectives:
- From the perspective of different typologies of freshwater supply managment systems from a landscape architectural and hydrological point of view. Think of single well rainwater harvesting systems in Venice to the underground canal qanat system in Middle East or the extensive sand infiltration system in coastal dunes as we know in the Netherlands.
- In the second place it looks at how different types of cities have dealt with meeting their freshwater demand supply in different types of cities. For instance an ‘island city’ like Venice, surrounded by salt sea water, with no freshwater available from groundwater and rivers or streams, for centuries relied on a public rainwater harvesting system. ‘sea harbour cities’ at the end of a river are usually prone to salination and land subsidence. They often import water from outside the urban territory like through the aquaducts of ancient Rome. ‘Valley’ or ‘River Basin Cities’ usually benefitted, until recently, from fresh mountain water in streams or free flowing artesian water from natural or man made wells. But also in these types of cities, like Bandung Indonesia, overexploitation of groundwater has exhausted the shallow artesian wells. Urban dwellers and industries have resorted to deep well pumping exhausting deep acquifers that can not be regenerated.
- In the last place it will look at the potential of historical freshwater supply typlogies for the different types of thirsty cities.
