Project Status (Updated June 8, 2021)
The Contractor will begin potholing on private properties starting in late June so they can determine the depth of the pump tanks. They will be contacting and coordinating with private property owners before going onto private properties. Starting in late June, they will be sawcutting the pavement along Kitsap Way to get ready for pipe trenching. Pipe installation along Kitsap Way will start in July and go through August.
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.
