Recognised for their unique and significant long-term contributions to advancing water science and management


Responding to global water challenges, IWA progressive agendas support sustainable urban and basin-related water solutions.

In the past two decades, Brisbane has experienced the millennium drought (1995 – 2009) and two significant floods (2011 and 2013), and as a subtropical city it is also affected by frequent and severe storms. These experiences have driven Brisbane to adapt, recover and thrive in the face of these climatic events.

Águas do Porto, the utility responsible for urban water cycle management, has taken several measures to deal with ecosystem decline and prevent pollution, following the principles of River Basin Management Plans under the Water Framework Directive.

Skanderborg Forsyning
