The content of these policy briefs is based on the outcomes from a series of workshops which took place in several different European cities in 2012. The workshops were designed to help governance bodies and citizens groups explore their visions for the future of urban water services. Participants discussed what they saw as key challenges for urban water services, as well as the benefits and weaknesses of potential interventions that might be used to help address those challenges. Most of the policy briefs highlight the key interventions that were discussed in the workshops, including developing alternative water sources, demand management measures, and general measures to strengthen the governance of the water sector. Each of the briefs provides a description and general context for the intervention, a summary of the responses towards each intervention that arose from the workshops, and a brief summary of the key factors that water service providers (or other governance bodies) should consider when developing and discussing these interventions. The last policy brief discusses citizen responses to innovative technologies. This material is intended to help water service providers (and other governance bodies) develop a clearer picture of potential responses to customer-focused technologies in the water sector (e.g. smart meters) in order to better anticipate such responses. These documents are not intended to present comprehensive guidance on each intervention and its associated responses. Instead, they are intended as snapshots of current thinking around urban water services across a range of European contexts.
