Technical Committees

Scoping Committee—consisting of representatives of local governments, utilities, state agencies, tribal governments, and environmental interests. The purpose of the committee was to explore what might be included in updated Coordinated Water System Plans (CWSPs). This committee has transitioned into the Coordinating Committee.

Coordinating Committee—The role of the Coordinating Committee is to review, oversee and coordinate a number of studies, analyses, and projects that will produce new information useful for water planning activities.

Executive Committee—The six-member Executive Committee assists in the logistics of this planning process. Their role includes setting the agendas, calling committee meetings, resolving disputes, pressing for the completion of desired outcomes and deadlines, assuring open communications, and facilitating both the Coordinating Committee and Technical Committees.

There are five technical committees being overseen by the Regional Water Supply Planning Coordinating Committee:

  • Climate Change—This committee will assess climate change impacts on water demand, water supplies and instream flows.
  • Reclaimed Water—This committee will assess the use, cost, and benefit of reclaimed water as a feasible source of supply for non-potable purposes.
  • Small Water Systems—This committee will address public health, resource management, and planning problems associated with the creation of new small water systems, failing small water systems, and associated well issues.
  • Source Exchange Strategies—This committee will identify, evaluate, and help develop voluntary projects for the replacement or supplementation of water supply sources that have been shown to adversely affect salmon runs with water from supply sources with less impact on salmon runs.
    • Pausing Groundwater Extraction--A joint subcommittee of the Source Exchange and Tributary Streamflow committees is overseeing a study on seasonal pausing of groundwater extraction wells. The study includes a literature review, modifications to a model that can evaluate groundwater extraction, data compilation on groundwater wells in the Cedar/Sammamish and Green/Duwamish watersheds, an assessment of potential improvements through well resting, and identification of wells with potential for flow restoration from seasonal pausing. The study and related appendices have been incorporated into the final report from the Source Exchange Strategies Committee.
  • Tributary Streamflow—This committee will identify the location and ranking priority of flow-impaired tributary streams that are evaluated to most benefit from flow restoration in order to help maintain and recover salmon runs.

The Central Puget Sound Water Suppliers' Forum's (Forum) (external link) is overseeing the following two committees:

  • Regional Demand Forecast—This broad-based technical committee is expected to develop the best available information on future municipal water demands to assist in making more informed decisions on future water supplies; it will include a projection of future municipal water needs in King, Snohomish and Pierce counties, and will likely include a range of forecasts with differing assumptions (e.g., different levels of conservation).
    • Independent Review--A subcommittee consisting of both Forum (water utility) and non-Forum (non-water utility) members is overseeing an independent review of the regional demand forecast model. Funded by a grant from the Washington Department of Ecology, the independent review was conducted by Dr. John J. Boland, PE, Professor Emeritus from Johns Hopkins University, and Dr. Bonnie Kranzer Boland, AICP. The review was undertaken in two phases. The first report, dated December 19, 2007, is an interim review. The final report, dated June 9, 2008, reviews a more complete version of the model.
  • Supply Alternatives—This committee will provide an inventory and assessment of municipal water supply sources that might be used to meet future water supply needs within King, Pierce, and Snohomish counties, and develop multiple supply scenarios to meet any shortfall between projected demands and existing supplies. This work will build upon earlier work done by the Forum in the 2001 Water Supply Outlook.

Refer to Attachment B of the Planning Framework Summary (October 31, 2005) for recommended questions to guide the technical committees on the various topic areas.
