Water Comprehensive Plan

2018 Water Comprehensive Plan 

On October 7, 2019 the Sammamish Plateau Water & Sewer District Board of Commissioners adopted the 2018 Final Water Comprehensive Plan (2018 Final Plan). The 2018 Final Plan is comprehensive, considering all aspects of provision of water service, and describes the strategies that the District plans to implement over the next 20 years to continue to supply high quality water to its customers, meet its present and future supply and infrastructure needs and continue to comply with complex federal and state water quality regulations.

The 2018 Final Plan is now being submitted to the Washington State Department of Health, King County, the City of Issaquah, and the City of Sammamish, for their formal approval.

The 2018 Final Plan is available here for review:
