Tacoma Water's Comprehensive Water System Plan serves as a tool to assist Tacoma Water in making the best use of available resources in order to provide quality water services and protect the health of its customers.

Tacoma Water is required by the Washington State Department of Health to update its water system plan every six years. These efforts include stakeholder and public outreach activities that ultimately result in the publication of several draft documents.

In 2008 the Department of Health approved the 2006 Tacoma Water Comprehensive Water System Plan Update. This update consists of Volume I (dated July 2007) and Volume II (dated August 2006 and titled Green River Watershed Management Plan).
