The Departments of Health and Ecology – with assistance of a Water Reuse Advisory Committee, interested stakeholders, and a consultant team of nationally recognized water reuse experts – developed standards for most applications of reclaimed water.
The standards emphasize public health protection and provide design, treatment and use area criteria for the following reclaimed water categories: general requirements (e.g., land application, impoundments, commercial and industrial uses), use in both natural and constructed wetlands, and groundwater recharge (direct and surface percolation). The Washington State standards are some of the most comprehensive and technically sound reclaimed water standards in the United States.
The file below contains the latest version of the Water Reclamation and Reuse Standards developed by the Departments of Health and Ecology.
