Log jacks sit along the Wynoochee riverbank with the City of Montesano wastewater treatment plant in background
Montesano, WA is a town of around 4,000 located 40 miles southwest of the state capital. For years, the City’s wastewater treatment plant has been peacefully located along the banks of the Wynoochee River. However, now movement of the river threatens to overtake the treatment plant. The bank continues to erode at an alarming rate of 17 feet per year. If this pattern were allowed to continue, the river could breach the plant, sending millions of gallons of raw sewage spilling down the Wynoochee, into the Chehalis River, affecting many communities along the way and eventually making its way to Puget Sound.
