Water and wastewater staff manage the wastewater plant and pump station facilities that collect and transport sewage from homes, businesses and industries. They manage the wastewater through a complex process where the solid remains are used to make compost and the water remains are treated and discharged back into the Nooksack River – clean and ready to be utilized by fish, other aquatic species and county residents downstream.
The wastewater treatment plant was built in 1975 and the compost facility was built in 1996. The wastewater treatment plant has an average annual flow of 1.2 MGD, and produces 600 dry tons of biosolids per year and about 4000 cubic yards of compost. About 70 tons were used to make the compost. Lynden sells compost to local nurseries, contractors, landscapers, and the Lynden Parks Department and Cemetery District.
