Illahee State Park

Illahee State Park

PROJECT HIGHLIGHTS

Commissioned May, 2011 Domestic WW, Greenfield Permit(s); Discharge 6/NA/0.2    (TN/TP/Turbidity) State Park, RV ⇒ Leach Field MMF Capacity: 0.004 MGD $462.5/gal 0.25 FTE (Full‐Time Employees)
MBRs were selected to minimize footprint on park property and provide the capability for remote operations, nutrient removal.

DESCRIPTION

Washington State’s response is the Puget Sound Initiative – an action plan to protect and restore the environmental health of Puget Sound. The Park decided to use membrane bioreactor (MBR) technology to increase the level of wastewater treatment for the selected park. The wastewater at the park includes RV waste, which results in higher than normal influent loadings, especially nitrogen.   MBRs were also selected for their ability to minimize site footprint on park property and provide the capability for remote facility operations, nutrient removal, and the opportunity for reuse of the effluent. Illahee State Park use septic systems and drain fields. The park is a moderate to high geologically hazard area located within a Priority 2 Bald Eagle nesting and roosting area.
