Wastewater Comprehensive Plan
2022 Wastewater (Sewer) Comprehensive Plan
On September 26, 2022 the Sammamish Plateau Water & Sewer District Board of Commissioners adopted the 2022 Wastewater Comprehensive Plan for Public Distribution (2022 Plan). The 2022 Plan is comprehensive, providing a long-term strategy and road map for the District’s sewer utility over the 6-year and 20-year planning periods. The Plan analyses methods for provision of effective and efficient sewer service to existing sewer customers and approaches to expand sewer service to properties within the District’s urban sewer service area that do not currently have sewer service available.
The 2022 Plan is available now review and comment, with comments requested by December 30, 2022.
