Developing Standards/Criteria for Various End Uses of Recycled Water

Water reuse practitioners around the world need and want a set of universal standards or criteria on which they can rely when designing a water reuse facility/project. There are currently no national standards in the U.S. Individual state regulations govern the design of various reuse facilities, although not all states have adopted standards. For states with standards, they do not necessarily cover all types of reuse applications. The level of stringency of state standards varies from state to state. California’s Title 22 regulations are typically viewed as the most stringent. The project assesses potential alternatives to achieve national consistency in the quality and safety of reclaimed water produced through reuse, including regulations/criteria, guidelines, industry “standards” or voluntary standards of practice, and other options.
