ABSTRACT
Only a very small fraction of the potable water produced by urban centres is used for a need requiring the highest-quality water. Urban water infrastructure has evolved over the past century without considering whether past practices make sense for a future with stressed ecosystems and a changing climate. Smart water techniques are vital to optimize existing infrastructure. However, for urban water servicing of the future, guiding principles developed through consultation, a long-term vision, and tailor-made plans for local conditions are needed. A coordinated research agenda to address many common challenges could support implementation of the plans and the vision.
