Working site for multiple agencies and organizations to collaborate on data, information, and pragmatic tools to assist in water resource and supply planning in the region. 


Countywide Water Supply Planning

    In February, 2005, King County and Cascade Water Alliance (Cascade, external link) initiated a water supply planning process as a critical step in meeting growing challenges to the drinking water supply across King County. For details, please read the Memorandum of Understanding or MOU (Acrobat pdf) signed by Executive Ron Sims and Cascade Water Alliance Board Chair Grant Degginger. This MOU commits King County and Cascade to a planning process that is expected to include:

    1. Clearly defining long-term water needs -- both instream and out of stream -- factoring in prudent water-conservation and demand-management practices;
    2. Prioritizing future water supplies to meet such needs, including alternative sources such as reclaimed water, "a drought-proof source that will be available in large quantities from the regional Brightwater treatment plant starting in 2010," as County Executive Ron Sims has said;
    3. Identifying new water supply and required infrastructure needs, and who is responsible for making them happen;
    4. Collaboratively planning for times of drought and water shortage, such as what the region faced in 2005; and
    5. Establishing policy guidelines for processing water-rights applications and for other water-resource management decisions at the state and federal levels.

    King County and Cascade Water Alliance encourage other utilities and stakeholders to participate in the planning process. For more information, please read about King County's water supply planning efforts and contact Dave Monthie or Jane Lamensdorf-Bucher for more information.
