Subject: Supplement #1 - Contract with Tetra Tech, Inc.
Final Design - Port Hadlock Sewer
Statement of Issue: Supplement #1 extends the completion date for this design contract.
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 Ft 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 with the
next major step being advertisement of bids to select an MBR equipment supplier.
Fiscal Impact/Cost Benefit Analysis: $1,472,665. The Washington State Legislature recently
provided $1,422,000 as a direct appropriation through the Department of Commerce to fund
this work.
Recommendation: Please sign three (3) originals of Supplement #1 and return two (2) fully
executed originals to Public Works.
