Global experiences in water reuse

This report provides an overview of global experiences in water reuse. The primary objectives of this report are to: review a range of drivers, barriers, benefits, and incentives for water reuse and wastewater use outside of the United States; outline the state of, and geographic variation in, water reuse and wastewater use; and review paths for expanding the scale of safe and sustainable water reuse and wastewater use in different contexts. Discussion is provided to address these objectives; it draws on experiences from 41 global case studies that provide an array of approaches to safe and sustainable water reuse. While the USEPA guidelines focus on water reuse, the global abundance of wastewater use and the gray lines dividing water reuse and wastewater use have led the contributors to broaden the scope of this report to discuss both water reuse and wastewater use outside of the United States.
