2018 Water System Plan

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 ten years. These efforts include stakeholder and public outreach activities.
