Sewer System

Shelter Bay operates its own sanitary sewer system, comprised of a network of buried piping for wastewater collection and an on-site wastewater treatment plant (WWTP). The plant is located within the Community just south of the Swinomish Veteran’s Cemetery on Samish Way. There is a network of sewer collection piping and four lift stations located in various places in Shelter Bay. The lift stations augment the power of gravity to pump the sewage to the treatment plant. The collection system serves 870 connections and has a total of 56,921 lineal feet (approximately 11 miles) of 8″, 10″, 12″, and 15″ gravity collection piping. The collection system was originally constructed in the early 1970’s
