International Water Association

The International Water Association (IWA) is a global organization that works with an interdisciplinary network of water professionals and partners to create a water wise world. Our experts collaborate and combine their knowledge to spread practical know-how throughout the entire water cycle to help us reduce, reuse, and replenish water resources. IWA is the global reference point for water professionals working in all aspects of the water cycle. Our network of around 10,000 members, and over 500 companies worldwide enables us to help water professionals deliver innovative, pragmatic and sustainable solutions to challenging global needs. Drawing on the over 75-year heritage of our original founders, we combine global expertise in research, practice, regulation, engineering, consulting, industry and manufacturing. In 1999, the International Water Services Association and the International Association of Water Quality joined forces to form the International Water Association (IWA), bringing the science and practice of water management closer together. Today, we are a strong and thriving global organisation that continues to deliver on our original vision.
