Ivan Illich and Jamie Linton have both argued that our current technological relation to water constitutes an abstraction. Developing this insight in the context of phenomenology, I draw on Michel Haar's French translation of Gestell—the essence of technology, according to Heidegger—as ‘consommation’ (consumption), to put forward a criticism of the abstract status of water in postindustrial, consumer societies. I propose in its place a concrete, phenomenological approach, according to which a policy of ‘letting water appear’ can not only play a significant role in the unconcealment of poiēsis— Heidegger's response to the question concerning technology—but also form the basis of a renewed urban water policy. Four key examples of letting water appear are examined: Daylighting urban rivers and streams; harvesting local rain and ground water; treating wastewater on-site using ‘living machines’; and attuning demand to local water flows. I conclude by suggesting that urban water policy cannot be reduced to integrated water resource management, for the transition to sustainability also requires a fuller understanding of the phenomenological issue of ‘letting appear’ (poiēsis).
