Water Reclamation Facility
Reclaimed water is wastewater that gets treated to such a high level that it can be used safely and effectively for non-drinking water uses such as landscape and agricultural irrigation, heating and cooling, and industrial processing. Reclaimed water is available year-round, even during dry summer months or when drought conditions can strain other water resources.
Snoqualmie Water Reclamation Facility
The City of Snoqualmie owns and operates the Water Reclamation Facility (WRF) which is a state-of-the-art facility sized to treat up 2.15 million gallons of sewage each day. The WRF includes an automated perforated plate screen, a vortex grit chamber, two advanced oxidation ditches, two secondary clarifiers, 3 tertiary sand filters, and ultraviolet disinfection.
Solids are aerobically digested in a solids handling facility prior to dewatering with a centrifuge and sent to a beneficial use facility for agricultural land application in eastern Washington. The facility relies on a modified Carrousel process train for biological treatment that removes biochemical oxygen demand (BOD), total nitrogen (TN) and total phosphorus (TP) to meet current effluent guidelines. By relying on such natural processes, the facility uses less energy and materials than other facilities of comparable size. During summer months water is treated to Class A reclaimed standards for reuse as class A irrigation water.
The facility has been operating 24 hours and 365 days year since original construction in 1997. Currently the City is in the process of completing a series of upgrades to replace aging equipment with more modern technology and provide the Cities needed capacity.
