PNWSC Seeking Landowners for Septic System Project

(Belfair, WA) In support of a Washington State Department of Ecology grant, lower Hood Canal shoreline landowners interested in Hood Canal water quality are invited to participate in a project to determine the effectiveness of a new onsite septic nitrogen removal system.

A  recently completed research project by the Washington State Department of Health and the University of Washington has shown that a low cost, two-stage Recirculating Gravel Filter (RGF) and Woodchip Bed System can reduce nitrogen output by greater than 90% and fecal coliform bacteria by greater than 96%. This project will include design and installation of a RGF and woodchip bed system between existing septic tanks and drain fields for three homeowner shoreline residences or businesses to evaluate actual site performance and landowner acceptance during two years of operation. Public education, communication and site visits will be a key component of the program.  A final report will include nitrogen and fecal coliform removal effectiveness, costs, landowner maintenance considerations, public acceptance evaluation and define benefits if this technology were applied across the lower Hood Canal shoreline.

Selected sites must be shoreline properties on the north or south shores of the lower Hood Canal from Union and Tahuya to Belfair and have a permitted, operating on-site septic system. Landowners interested in participating in the project should contact Dave Kangiser at (360) 275-3575, extension 25, or email
