Port Hadlock Wastewater System
Jefferson County, WA is developing a sewer system for the Irondale & Port Hadlock Urban Growth Area (UGA) to provide wastewater treatment for local residents and businesses. The sewer system has been identified as a critical element for increased regional economic development. When construction of the sewer system is completed, the Irondale & Port Hadlock UGA will be able to support affordable housing, medical facilities, higher density multifamily residences, senior housing, as well as commercial and industrial development.
Below are links to the DRAFT 2020 Sewer Facility Plan update. These documents contain updates to the 2008 Sewer Facility Plan and are consistent with the information contained in the May 2019 Value Engineering Review (Feasibility Study). The updated plan reflects the use of new pre-fabricated, modular MBR treatment units and a pressurized collection system to reduce initial project costs. Zoning, population, and project phasing remain unchanged from the 2008 Plan. Several growth scenarios are analyzed. As of September 2020, this DRAFT plan is currently under review by the Department of Ecology.
In 2018, property owners from the Port Hadlock “Core Area” presented the County with a petition indicating strong support for the sewer and potential interest in forming a Local Improvement District. In response, the County engaged design consultants to perform a feasibility study to determine what steps could be taken to reduce the cost of a “startup” sewer system to serve the Core Area while still allowing for future expansion to serve the larger Urban Growth Area (UGA) when demand occurs.
The results of the feasibility study were published in the Port Hadlock Wastewater System Value Engineering Review (May 2019.)
The study showed potential for significantly lowering startup costs by serving the Core Area with a newly available modular treatment plant unit. This system still utilizes previously approved membrane bioreactor technology to treat wastewater to “Class A” Reclaimed Water standards required by the Department of Ecology. It offers the flexibility of allowing for future expansion as well. The study also estimated the amount of initial cost savings that could be realized using a pressurized collection system instead of gravity pipes and pump stations and focused on other cost saving measures appropriate for a smaller system designed to initially serve only the Core Area.
Jefferson County has since been engaging with a newly formed Sewer Working Group (SWG) made up of stakeholders in the Core Area to find ways to advance the project. Related materials are linked below as PDF files.
