Our system protects the environment by ensuring that all waste is contained and isolated from soil and groundwater. The site's multi-layer composite liner system is built to strict engineering standards, using a 2-foot clay bottom and 60-mil high-density polyethylene (HDPE) liner. The final cap includes a soil foundation, 40-mil HDPE liner, drainage and soil layers, with a vegetative cover.
Groundwater is monitored by 14 monitoring wells - four upgradient and ten downgradient. Monitoring results are submitted to the Spokane Regional Health District and the Washington State Department of Ecology.
Leachate Collection & Treatment
All waste cells have a leachate collection and removal system, which includes an automated pumping system that maintains sump levels below regulatory standards. Leachate is collected and managed in double-lined evaporation ponds.
Additional Services Provided
Recycling services for asphalt, cardboard, concrete, heavy plastics, metal and wood.
Waste Approval Process
Waste Management has a defined waste screening protocol for each of its non-hazardous waste facilities, which protects both our employees and the environment. For all industrial and special waste streams, the generator or agent must complete a Generator's Non-Hazardous Waste Profile (available online at wmsolutions.com) for review by our technical staff.
Community Partnerships and Involvement
Waste Management is proud to be an active supporter of community events and programs that make our area a cleaner and healthier place to live, work and play.
