Water System Plan
Planning For Reliable Water Service
As a Special Purpose District established specifically for, and singularly focused on water, we’ve been developing and updating a proactive Water System Plan since 1910.
All water systems in the State of Washington are required to complete a Comprehensive Water System Plan Update every 10 years. The purpose of this plan is to provide a comprehensive road map that encompasses:
Planning and engineering efforts that describe and analyze system competency for the projected future demands on the water system
A detailed capital improvement plan that addresses system deficiencies through the 10-year and 20-year planning cycles
A review of the existing water system, design criteria, system analysis, and operations programs
This effort helps us ensure that our water system, its associated operations, and equipment are being managed and maintained as safely, efficiently, and cost-effectively as possible.
