Pump Station Monitoring White Papers and Case Studies

  1. Minimizing Energy Use At Pump Stations With Extreme Variable Flows
    3/1/2016

    Every spring, the wastewater municipality in Dalarna, Sweden, experienced melting snow and heavy rainfall that caused a dramatic increase in pump station inflow. To handle this seasonal volume, the station had oversized pumps that consumed more energy than needed during drier months. This case study illustrates how the installation of a variable-speed pump controller decreased energy consumption by almost 50 percent while allowing for variations in flow.

  2. Bury A SITRANS MAG Sensor? Sure!

    A large east coast water supplier faced a number of challenges with one of its pumping stations. It was built more than 35 years ago on a 25’ earth mound (“ant hill”) to protect it from flooding, the pumping station was becoming very expensive and inefficient to operate.

  3. Dry Pit Submersibles Lower Costs And Eliminate Unscheduled Maintenance

    A utilities department was experiencing frequent unscheduled maintenance visits and corresponding unbudgeted repair bills for the pumps at the township’s main pump station.

  4. Pump Station’s Non-Dispersibles Problem: Solved
    9/17/2015

    Sun City, AZ, has had the same wastewater treatment plant since the '70s, along with a new, expensive problem: non-dispersible waste.

  5. Monsters Protect Pump Station, Weather Storms In Scotland
    7/14/2015

    Pump blockages and rags are a significant barrier to energy and operational efficiencies at pump stations, causing unscheduled shut downs, safety hazards for operators, costly equipment repairs and increased power usage due to a decrease in the pumps’ hydraulic performance. Scottish Water observed these negative effects caused by an influx of wipes and rags throughout a network of area pump stations. Engineers looked to a proven, powerful solution in the form of two JWC Environmental Channel Monster® grinders at one of their most problematic sites.

  6. Lift Station Upgraded After Rainstorm Causes Flood And Electrical Short
    7/13/2015

    Read the full case study to learn how the installation of the three Flygt horizontally mounted dry pit, flood-proof NZ-3171 submersible clog-free pumps immediately offered a 25 percent boost in efficiency at a lift station in Manitoba, Canada, after a motor had shorted out due to excessive moisture, and could not be replaced.

  7. Robertson County Water Supply Corporation Adopts VTScada Software
    7/10/2015

    Serving just over 16,000 residents in eastern Texas, the Robertson County Water Supply Corporation (RCWSC) operates a small rural water system with five water plants, four wells, one booster pump station, and approximately 350 miles of PVC pipe. In December of 2014, their systems integrator, Express Electric, recommended that they adopt VTScada software from Trihedral to remotely monitor and control their plants.

  8. Sulzer Pumps Reduce Downtime At Water Utility
    6/26/2015

    Winslow Township — the largest town in Camden County, NJ — sought relief from its clog-prone, unreliable pumps.

  9. City Improves Reliability For Chlorine Residual Compliance, And Cuts Chemical Costs, Through Replacement Of Pump With Special Vacuum Feeder For Bleach, LAS, And Polyphosphate
    6/23/2015

    The public works director responsible for a southwestern U.S. city’s drinking water supply reports multiple benefits from replacement of a problematic peristaltic pump system with a special liquid vacuum feeder system for bleach, liquid ammonium sulfate (LAS), and polyphosphate feeds at one of its well sites.

  10. Addressing Chronic Flooding In Texas
    6/18/2015

    The city of El Paso, TX, lies on the tip of the Chihuahuan desert, and it is not uncommon for a year’s worth of rain to occur in a matter of days during the summer.
