Construction – Current Projects

The Class A water reclamation facility has a design capacity of 0.67 million gallons per day. It was financed with the aid of a $5.3 million Clean Water State Revolving Fund Loan.  The facility uses an existing oxidation ditch biological secondary treatment system and added flow equalization, coagulation/ filtration and disinfection facilities to meet reclaimed water standards.  Sequim also extended the marine outfall by 1,320 feet to allow opening of impacted shellfish beds.  The coagulation/filtration components include a lift station, coagulant feeds, metering pump, flocculation chamber, gravity feed anthracite media filter by general filter.  The disinfection system is a Trojan low-pressure, low-intensity ultraviolet system.  On-line process monitors provide continuous monitoring of flow, turbidity and other important parameters.  The reclamation facility also includes alarms to automatically divert substandard flows and notify operators.  A holding pond with a recycle pump returns substandard flows for treatment.  Only reclaimed water meeting Class A standards is discharged from the facility.
