• Ross Valley Sanitary District in San Rafael, California services approximately 47,000 mostly residential customers over a 27 square mile service area. They have 5 major pump stations, which is where Ross Valley found themselves having the most trouble. The existing channel grinders were simply not reliable. “It was a constant headache,” said Philip Marcantonio, Senior Collection System Worker. “The pumps were ragging up sometimes twice a week and sometimes twice a day.” The plant reported that the machines were not efficient at all. “It was a lot of extra work on us to keep the stations going,” Marcantonio said. On top of that, the constant downtime was causing even more than extra work; it was costing the district a lot of money. They knew this was not a sustainable system to keep their plant and stations running.

  • Prior to the installation of the Duperon Self-Cleaning Trashrack at their intakes, the City of Dallas Hampton Road Pump Station operated without any protection in front of their stormwater grating. “We just had a grate in front with no mechanical cleaning,” remembers Dhruv Pandya, District Manager for the City of Dallas Department of Flood Control. “The pumps were suffering. They were continually getting clogged, and they didn’t have enough water coming in to function properly.”

  • Darey Hjelmeland, Plant Supervisor for the Rural Municipality of Gimli, manages the processing of incoming septage, creating a challenging blend of influent that can include a wide variety of debris: heavy rags, rocks, clothing, metal, soda cans and bottles, and more.

  • Hydrogeneration is the dominant source of energy in New Zealand, providing approximately 70% of total electricity. The Hornwort, a submersed, free-floating perennial which can reach nearly 20 feet of height above water, has invaded New Zealand’s waters. The plant quickly proved to be an issue for Genesis Energy at the Tokaanu Power Station, a 240 MW hydroelectric power station.

  • The Wayne County Downriver WWTF in Wyandotte, Michigan, is a CSO facility servicing 13 area communities with an average flow of 40 MGD. For wet weather and storm events, the plant is rated for 225 MGD—second only to Detroit in the state of Michigan. The plant is home to seven screens: four used during everyday flow, and an additional three accessed primarily during storm events.

  • The City of Grand Rapids, Michigan Wastewater Treatment Plant has four channels with a design flow of 61.9MGD, and which routinely manage up to 90MGD during storm events. An on-site retention basin, designed for the wet weather the city frequently experiences, holds up to 10M gallons—which, during storm events, can mean a potential of 125MGD-135MGD through the screens.

  • Kansas City is a dynamic metropolis on the banks of the Missouri River, home to nearly half a million residents—and a constant stream of visitors coming to enjoy the world-class barbecue and music scene. All that activity puts steady pressure on the city’s water and wastewater infrastructure. KC Water is the utility charged with meeting those needs.

  • The Drake Pump Station, located in Saginaw, Michigan experienced chronic pump maintenance due to flushable wipes. Although the dry pit pump station represented only 0.1 million gallons per day (mgd) of flow in the city’s collection network, it required a substantial amount of servicing – up to three times a week. This consisted of two operators spending four hours manually removing rags in a confined space entry to clean out the clogged pump. It was a dirty, unplanned, and time-consuming task.
