What can water supply and sanitation utilities do to mitigate climate change? Linking sustainability, efficiency and high service levels

Wed 21st March / 10:30-12:00  

In order to reduce GHG emissions, there are several possible lines of action for water and sanitation utilities, such as water recycling, increased energy efficiency, nutrient recovery, water losses reduction and so forth. Although many times these alternatives are seen as merely technological issues, a set of policies, sharing practices and deep commitment and support from stakeholders are required to put them into action. This session will discuss ways to implement low carbon technologies, policies and procedures concerning water supply and sanitation utilities, avoiding focusing on one-size-fits-all solutions and trying to hit on the whole picture of the experiences considered.
