Three 48-inch pipes coming into a pump station at the waste water treatment plant begin the process of treatment.
Sewage goes through a settling process to take out all the rocks, sand and other "course aggregate."
Sewage goes into a large settling basin.
Sewage is run through an aeration basin where microbes feed on the sewage. Air is pumped into the basin to keep the water moving for the tiny organisms to feed.
After the aeration basin, the sewage goes to another settling basin where the process of removing the microbes begins.
Chemicals, including bleach, are added to the sewage at this step.
Effluent is released to the river and for testing in the final step.
Andrew Henderson, Wastewater Treatment Plant plant operator, works in the control room at the plant where computers monitor and control most of the plant's operations.
