Conference Information

Cincinnati, Ohio will host a joint IWA International Conference on "Water Efficiency and Performance Improvement: Smart Strategies for the 21st Century".

Cincinnati, Ohio will host a joint IWA International Conference on the topics of Water Efficiency and Performance Assessment of Water Services. We invite you today to mark your calendars and visit one of the most wonderful cities in the United States of America.

From April 20-24, 2015 we will have the opportunity to tackle the challenges that water services are facing in the 21st century. Water scarcity, climate change, increasing demand, and the deterioration of water resources all require a dedicated search for more efficient solutions -- ones that need to be properly measured and assessed to guarantee their continuing efficiency value.  This combined conference event will gather a large network of water professionals to exchange experiences on key topics on urban water.
