FT 4: West Point Wastewater Treatment Plant

West Point

Field Trip 4: West Point Wastewater Treatment Plant

For our Grand Finale, we will track the water that goes through the “human” engineering of pipes and treatment plants, to the Sound, by visiting the West Point treatment plan.


The plant is part of King County's regional system that treats wastewater for about 1.5 million people and covers 420 square miles in the Puget Sound region. Every day, the West Point Plant cost-effectively treats wastewater and stormwater from homes, offices, schools, agencies, businesses and industries in Seattle, north King County, south Snohomish County, and some areas of Lake Washington.


This assignment is due on Friday the 10th! Please email an electronic version no later than midnight on Friday.

No late assignments (for this trip or previous labs) will be accepted after Friday the 10th.
