This report examines the current system of water abstraction and pollution charges in operation in Brazil. It assesses the current system's implementation challenges and provides possible solutions. The report explores how water charges can be both an effective means for dealing with water security issues, and a tool for enhancing economic growth and social welfare. Specific analysis is put forward for three case studies in the State of Rio de Janiero, the Paraiba do Sul River Basin and the Pianc-Piranhas-Au River Basin. The report highlights that water charges need to operate in conjunction with an effective water regulatory regime and concludes with an Action Plan based on practical steps and recommendations for its implementation in the short, medium and long-term.
