Part 1: AFT Arrow

By Matt Steiner & Jen Murphy

Many utility ratepayers are currently struggling with economic security. At the same time, energy costs are rising and the impact of uncertain material and equipment markets is driving project costs up and making capital planning less predictable. As such, it is important that as engineers that we leverage all available tools to optimize each project’s capital and operational costs. Almost just as important is sharing what we learn with not only our colleagues, but the wider engineering community.

The Aeration systems at Resource Recovery Facilities (Wastewater Treatment Plants) account for 30 to 80 percent of a plant’s energy usage, making them typically the single largest source of energy use within the facility. They’re also the most complex and capital intensive systems within a plant. This integral system, which ... (more)

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.
