  • Suwanee Creek pumping station, Gwinnett County, GA

    That's high head," says Roger Toebben, P.E., about the 350 feet of total dynamic head handled by the Suwanee Creek Pumping Station, which has been up and running since January 2001. "There are a few sewage pumping stations like this, but they're not real common." Very high static head and a long force main (42,500 feet) led to the notably elevated dynamic head, which meant that a ...


  • North Creek pumping station, King County, WA

    The new North Creek Pumping Station in King County, Wash., had to maintain the Department of Natural Resources' national reputation for outstanding reliability. To make sure it did, the design team applied the most advanced pump technology and vibration prevention methods. And the designers and utility put extra attention on meeting operations and maintenance needs. "We included folks from ...


  • Leachate Collection & Removal Systems – Pump Stations

    Romtec Utilities designs and supplies pump stations for many different types of applications, including leachate collection and removal systems. Leachate pump stations are required whenever water passes through a bed of solids and extracts contaminating elements. The most common scenario for collecting and pumping leachate is for landfills, but there are industrial ...

  • Computation Fluid Dynamic Modeling of a Proposed Influent Pump Station

    Traditionally pump intake hydraulics have been investigated using scale physical hydraulic models. Computational fluid dynamics (CFD) is a rapidly improving technology that in some cases can be used as a cost or time effective alternative to traditional physical model methods for evaluation of pump intake hydraulics. This paper presents a case study on the use of CFD modeling to re-evaluate and ...

  • Pump Station call outs a thing of the past - Case Study

    It’s 2:00 AM and a telephone rings in Eckville, Alberta. Rick McKinnon checks the display on his cell phone and groans. It’s another high level call out alarm from one of the town’s new sewage lift stations. He knows before he drives there that the system will be running on floats instead of the new ultrasonic level controller. ...

  • Deep soil mixing shoring system to construct a 60 MGD, 40 foot deep wastewater pumping station

    The City of San Mateo, CA operates three wastewater pumping stations on a 80' wide lot located in a residential area near San Francisco Bay. The age of the stations range from 12 to 50 years, the stations have difficulty pumping peak wet weather flows, and have structural and maintenance problems. For these reasons, a new station was proposed to replace the existing stations. The site layout is ...

  • Pumping Station Modifications to Comply with ANSI/HI 9.8 Improve Performance While Lessening O&M Requirements --- Two Case Studies

    Oversized wet wells in wastewater pumping stations lead to the accumulation of grit, sludge and floatable materials. Trench-type wet wells in compliance with ANSI/HI 9.8, the American National Standard for Pump Intake Design, minimize wet well volume and facilitate wet well cleaning through periodic pump down operations. Two pumping stations, the Cross-Irondequoit Pump Station (CIPS), Monroe ...

  • Improving Wet Weather Treatment Capacity by Converting a Two-Stage Activated Sludge Process to a Single-Stage Process

    ABSTRACTThe Western Virginia Water Authority (WVWA) operates a 42 mgd wastewater treatment facility which treats flows from the City of Roanoke and adjoining municipalities. In recent years, the WVWA WPCP has experienced peak wet weather flows exceeding 140 mgd, well above the plant’s existing peak flow capacity. Under these conditions, the plant is forced to rely heavily on flow ...

  • Desubmerge Your Submersible Pump

    A few decades ago, well, definitely not more than four, a contractor was introduced to electric powered submersible pumps. The crew’s first reaction was, “What! You’re going to throw that electric motor in the water? You’ve got to be crazy!” After a few weeks of getting comfortable with the subs, the whole crew was handling them like ...

  • Lift Station Odor Control Using CARUSOL Treating a Wastewater Collection System in a Mid-Western Township - Case Study

    Summary A mid-western township is responsible for operating and maintaining a combined sewer collection system consisting of 150 miles of pipeline and 28 pumping stations. The township does not treat the wastewater, instead contracting with a neighboring city for this service. The township has two final lift stations that transfer the collected wastewater to the neighboring system ...

  • An artificial intelligence approach for optimizing pumping in sewer systems

    This paper presents details of a fuzzy logic system developed for the control of sewer pumping stations for energy costs savings. This is part of an ongoing collaborative project between Anglian Water and the University of Sheffield. The model rules and operation are developed for one representative pumping station in order to enable the identification of potential benefits and inhibitors to ...

  • Vibration – What is It? How does it Affect My Operation? What can I Do About It?

    ABSTRACTThis paper describes how pump vibration can create problems in conveyance systems. Potential sources of vibration are reviewed as well as factors that affect pump vibration. Examples are presented that demonstrate pump vibration problems: (1) when a wet well level was lowered to obtain system storage capacity, (2) in a new installation, and (3) when one pump in an installation functioned ...

  • Hydraulic modeling - Bethel Park Municipal Authority - Case Study

    Treatment plant hydraulics is often overlooked as one of the most important aspects of treatment plant design, especially in plant upgrade scenarios where retrofitting new equipment or processes into the existing treatment train will create additional hydraulic restrictions.  Many existing plants already have a minimal amount of head available for passing peak flows through the system, which ...
