The Contractor (ACI) has completed installation of the sewer along Kitsap Way. Currently ACI is installing approximately 1800 feet of 3” and 12” sewer pipe along Madrona Point Drive and Shorewood Drive. This work will be disruptive to traffic along Shorewood Drive and Madrona Point Drive and may cause delays of up to 10 minutes. Grinder pump installation on private properties will begin in mid-December.
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.
