Economic Impact Study – Belfair Sewer System & Puget Sound Industrial Center

A regional infrastructure study examines how sewer expansion could support Belfair businesses, unlock industrial growth in PSIC South, and inform shared economic development decisions for Mason and Kitsap counties.

Mason County civic and business leaders are evaluating an extension of the sanitary sewer system serving Belfair, Washington into the southern portion of the Puget Sound Industrial Center-Bremerton (PSIC-B)1 in the City of Bremerton. This infrastructure project represents a potential interjurisdictional investment connecting an unincorporated Mason County community with a designated regional manufacturing and industrial hub in Kitsap County.

This study provides an objective analysis as stakeholders weigh the benefits of sewer system expansion. State grant funds for sewer system design and interjurisdictional cooperation present opportunities for regional growth. This study provides local governments, utilities, businesses, and community stakeholders with a rigorous, data-driven analysis to inform policy and funding decisions. It models and quantifies the potential economic contributions of the sewer system extension to the area economy, assesses impacts on Belfair's small business sector, and evaluates industrial development potential in PSIC South. The study provides support to decision-making that serves the economic development objectives of both Mason and Kitsap counties.
