Rainwater harvesting has long been part of the standard repertoire of the aspiring sustainable city. Its multiple benefits have been illustrated with a plethora of successful pilot projects in industrialised cities across the globe. The leap from niche to mainstream has, however, proved largely elusive. The UrbanRain project analysed experiences in applying nature-based solutions to urban rainwater problems in three cities: Stockholm, Barcelona and Berlin (Suleiman et al. 2019).
At IRI THESys we studied the sociotechnical pathways of rainwater harvesting in Berlin over the past 25 years. We conducted an analysis of the policy and planning contexts in the city and produced a database of over 100 rainwater harvesting projects begun since the early 1980s (García Soler et al. 2018). We subsequently conducted three case studies of emblematic projects representing public, grassroots and commercial initiatives in the city (Papasozomenou et al. 2019). Primarily through interviews with planners, engineers, architects, residents and other users we explored diverse visions of, and experiences with, rainwater harvesting in Berlin.
UrbanRain was funded for three years (2014-2017) by the Swedish research foundation Formas and involved partners at KTH in Stockholm, Sweden, and UAB in Barcelona, Spain.
