PNCWA – September Photo of the Month

The Pacific Northwest Clean Water Association (PNCWA) is dedicated to preserving and enhancing water resources.  They have resources available on their website and recently started a new, fun feature, “PNCWA Photo of the Month.”
The very first photo spotlighted a J-U-B engineer from Kennewick, Washington, working on the City of Walla Walla’s sewer collection system.   The system has over 150 miles of gravity pipe and serves a population of 32,000 residents.  J-U-B’s engineer sports a smile from down in a manhole where he was calibrating the City’s sewer collection model.  The meters captured sewer flows and real time storm events to measure inflow and infiltration, which was used in the model to project the impact of future growth, demands, and storm events.  See PNCWA web site
