Each year, World Water Day highlights a specific aspect of freshwater. Under the theme ‘Water and Wastewater’, the year 2017 provides an important opportunity to consolidate and build upon the previous World Water Days to highlight the symbiosis between water and wastewater in the quest for sustainable development.

UN-Water coordinates the World Water Day campaign and proposes a theme for each year. At the World Water Week 2016, UN-Water will present the plan for the World Water Day 2017 campaign, which is coordinated by UNEP, UN-Habitat, WHO and UNU, with the support of other UN-Water Members and Partners.
