Developing Urban Water Reuse Networks in the UK: A cross-disciplinary research initiative

GCSC Theme: Sustainable Resources

Lead: Dr Fuzhan Nasiri (UCL Bartlett School of Graduate Studies)

Main collaborator: Dr Sarah Bell (UCL Civil, Environmental & Geomatic Engineering)

GCSC (Nasiri) Water Reuse Networks poster

Project: Globally, reclaimed water is increasingly supplied for various uses due to aggravating water shortages caused by growing urban communities and climate change, more stringent wastewater effluent standards, and the expanding availability of high-performing and cost-effective water reclamation technologies. In the United Kingdom, however, there has not been a consistent and considerable pattern of urban water-reuse because historically there has been a sufficient supply of water. With highly increasing water demand in the South-East and more droughts due to climatic change, there is growing public and political consensus to establish water-reuse networks as part of a sustainable cities agenda. At present, the projects within the UK have focused on building and development-scale water re-use. However, greater opportunities exist, at a larger scale, with urban water reuse networks, to rebalance water use and demand, tap into unconventional water resources and improve the economic and environmental performance of urban water supply systems.

This project serves as a pilot study to investigate the feasibility, costs, and benefits of developing water reuse networks in urban areas with a particular emphasis on London. The aim of this pilot study is to develop a multi-university EPSRC research network and proposal by July 2012.
