Seattle Public Utilities Issues

Water System Plan Overview

The Water System Plan (WSP) provides direction for managing and operating the water system that serves both Seattle and a number of nearby cities and water districts. This plan describes how Seattle Public Utilities (SPU) meets current and future water demands, maintains the system and meets water quality regulations.

Seattle Public Utilities prepares the WSP under regulations adopted by the Washington Department of Health (DOH) for public drinking water suppliers. The plan must also be compatible and consistent with local and regional land use plans and meet the capital facility planning requirements of the Growth Management Act.

The latest version of the Water System Plan was approved in April of 2007.
