Description As water reclamation and recycling assumes a larger and more important role in the management of water resources, challenges in designing and locating piping systems for the distribution of reclaimed water are daunting. Existing standards require horizontal and vertical separations between potable water, reclaimed water, storm water and sanitary sewage that are rarely available in developed urban areas. While special construction practices are allowed to overcome these obstacles, regulatory approval is required on a case-by-case basis. This process is cumbersome, and increases design and construction costs, as well as the completion schedules. The Washington State Department of Ecology and the Department of Health developed this guidance in response to the need for a streamlined process and to assist utility engineers with pipeline separation design and installation.
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.
