Coordinated Water System Planning
the Public Water System Coordination Act of 1977 created Critical Water Supply Service Areas (CWSSA). All of Pierce County was declared a CWSSA in 1983. The first Pierce County Coordinated Water System Plan (CWSP) was created in 1988, and was updated in 2001.
2019 Plan Update
Many water resource, supply and land use changes have occurred since the CWSP was last updated. The Water Utility Coordinating Committee is working to update the plan. They will make a recommendation to the Pierce County Council in 2019.
Comprehensive Water System Planning
The Public Water System Coordination Act requires each purveyor in a CWSSA to develop a water system plan for their service area. The boundaries of the service area must be established in accordance with provisions of RCW 70.116.070.
The Washington State Department of Health is primarily responsible for water system plan approval; however, prior to that approval there are a number of plan review functions that are within the purview of local government.
In Pierce County, the Planning and Land Services Department has been tasked to ensure consistency of water system documents with local growth management plans and development policies and provisions of the CWSP.
Water Utility Coordinating Committee
The Water Utility Coordinating Committee (WUCC) periodically reviews and advises Pierce County on updating the Coordinated Water System Plan. The group also assesses whether the plan policies are being implemented as anticipated. Recommended revisions to the plan are forwarded to the Washington State Department of Health, the County Executive and County Council for review and adoption.
Committee members include at least one person from: County Council, Planning and Public Works Department, Tacoma-Pierce County Health Department, and each water provider with at least 50 connections.
The WUCC is currently in the process of planning the next update to the Coordinated Water System Plan.
