UPDATE SINCE LAST CCAC MEETING
• Conditional Approval of Facility Plan by Ecology
• The PUD Board has decided to withdraw from most
aspects of the project.
• The PWTF loan has been executed and assigned to
the County.
• Wastewater treatment and reuse in Sequim
Reasons to Consider Treatment in
Sequim:
• Sufficient excess capacity exists at Sequim WRF.
• Only minor upgrades to Sequim collection system needed
to accommodate Carlsborg flow.
• Less than 3 miles of 6” force main needed to connect.
• “State of the Art” facility producing Class A reclaimed
water.
• Good record of consistently meeting permit standards.
• Sequim aggressively pursuing utilization of reclaimed
water.
• Resolves siting issues in Carlsborg.
• Cost Savings
Preliminary Sequim Cost Proposal
1. Capacity Cost: Proportionate Share of
depreciated cost of shared treatment
facilities (Approx. $1.2-1.5 million for 20-year
Carlsborg flow projection.
2. Treatment O&M: $0.01 per gallon
3. Collection system O$M: $2.12 per foot on
approx. 15,000 feet of shared sewer lines
4. 10-15% surcharge on Treatment & Collection
O&M
