A new reclaimed water permit reminds us to use the right water for the right useAll water on earth is recycled, thanks to nature. Several sewage treatment plants in Washington are using their own process, instead of nature’s, to produce high-quality reclaimed water suitable for local use. Although reclaimed water has been around in Washington for more than 20 years, Ecology issued the state’s first administrative rule last year – the Reclaimed Water Rule (WAC 173-219). All new and reissued permits now follow our new requirements.
Many facilities are using reclaimed water to meet community water needs
After an extensive public process that started in 2006, we finalized the Reclaimed Water Rule in early 2018. This collaborative effort with the State Department of Health (Health) relied on many important partners across the state, including existing reclaimed water producers, tribal representatives, water utility representatives, consultants from engineering and other technical areas, and interested residents. After finalizing the rule, we worked with many of the same partners to complete our guidance manual for reclaimed water facilities – a document we call the Purple Book.
