Project Status (Updated November 26, 2019)
The City has selected Parametrix, Inc. as the design consultant for the project. The design is ongoing and approximately 30% complete. Approximately half of the properties have been visited and site investigations performed for locating the new grinder pumps. The consultant is nearly complete with the alternatives analysis for the new sewer mains along Kitsap Way and Shorewood Drive.
Project Overview
Many of the residential and commercial properties along Oyster Bay and Ostrich Bay are connected to sewer mains buried along the shores of these water bodies. These sewers are difficult to access and maintain and occasionally surcharge during heavy rain events. The City is in the process of eliminating/reducing the beach sewers over time.
The proposed project will eliminate lateral connections to the gravity sewer main buried along the Oyster Bay beach between Madrona Point Drive and Kitsap Way (approximately 3600 feet in length). The sewer main will remain in-place and be converted to a redundant pressure main, but with no lateral connections. Grinder pumps will be installed on upland properties (estimated between 50 and 60 properties) to replace the beach gravity sewer system. The grinder pumps will pump to sewer piping (location and route of piping to be determined) most likely along Shorewood Drive and Kitsap Way. Project benefits include pollution reduction by reducing potential sewer discharge into Oyster Bay, reducing sewer infrastructure in the marine environment, and eliminating problematic maintenance access.
