Description The Washington State Department of Ecology prepared the Reclaimed Water Facilities Manual, or Purple Book, with assistance from the Washington State Department of Health. This manual is intended to provide assistance for reclaimed water applicants, permittees, owners, generators, distributors, design engineers, and users of reclaimed water once a Reclaimed Water rule is adopted as Chapter 173-219 Washington Administrative Code (WAC).
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.

ADA Accessibility
The Department of Ecology is committed to providing people with disabilities access to information and services by meeting or exceeding the requirements of the Americans with Disabilities Act (ADA), Section 504 and 508 of the Rehabilitation Act, and Washington State Policy #188.
