This facility is located on Science Central within, and outside, Newcastle University’s new state of the art Urban Sciences Building. The facility comprises a number of research and demonstrator components that provide infrastructure for testing of novel sustainable urban drainage (SUDS) technologies, Green Infrastructure (GI) and Natural Flood Management techniques. Experiments can test individual components or as part of a ‘treatment train’. The laboratory extends to the ‘Building as a Lab’ (experiments and high resolution monitoring within the Urban Sciences Building), the wider Science Central site, and the city, through the Urban Observatory sensor networks. Non-commercial data is open source and made available through the Urban Observatory. In addition to the water labs, there are digital, energy, transport and other research facilities, and demonstrators that enable understanding of interdependencies, co-benefits, tradeoffs, and system integration.
