This project included construction of a new two story precast panel building, the housing of three influent trains, and is set up for one more train to meet upcoming future demand. Each train consists of a band screen placed in a specialty fabricated stainless steel tank handling all the primary influent via large modulating pinch valves, then pushing the solids through a washer/compactor and onto conveyor system which is then distributed into one of two dumpster rooms. Each room having specialty weight measurement controls that determine where the solids will be distributed into the dumpster for an even placed load, as well as, specialty designed curtains and ventilation system making this process surprising pleasant for all plant personnel and visiting bystanders. Each train is cleaned on a regular basis via a hot water flush from the boiler and available hot water lines throughout the facility. The facility is controlled via mostly modulating butterfly valves powered by the new air compressor and the updated compressed air system located in the existing, and recently updated, digester building. These updates accompanied by misc repairs and improvements to the existing facility affected by the work have modernized this plant to “State of The Art” status, operating at a current 25% to 35% capacity on average, as well as, outfitting the City of Bend with the tools and methods to meet the potential waste water demands for at least next 25 years, if not longer.
