This contract with the County's sewer design team led by Tetra Tech, Inc. is for final design, specifications, and cost estimates for the sewer treatment facility and pressurized sewer collection system for the Port Hadlock "Core Area" as shown in the Port Hadlock Wastewater System Value Engineering Review completed in May 2019. Analysis/Strategic Goals/Pro's a Con's: The Port Hadlock Wastewater System Value Engineering Review completed in May 2019 determined that significant initial costs savings could be realized by using newly available small, pre-packaged membrane bioreactor (MBR) equipment and a pressurized collection system. This will allow the sewer to start small in the Port Hadlock "Core Area" and grow as demand dictates. Design work is underway, currently at approximately 60% complete. Final completion is anticipated in summer 2022 with final approval by the Department of Ecology in September 2022. Fiscal Impact/Cost Benefit Analysis: $1,472,665. The Washington State Legislature has provided $1,422,000 as a direct appropriation through the Department of Commerce to fund this work.
