It is organized by the Water Environment Federation (WEF), which calls it "the largest annual water quality conference in the world" and says it has championed the water sector since 1928. The conference offers water education and training from frontline operations and compliance to circular economy strategies, alongside an exhibition of treatment technology and services.
