Field Evaluation of Different Check Valve Designs and Surge Pressure Measurement in a Municipal Water Pumping Station 

Overview: During a municipal water pump station upgrade, hydraulic engineers got approval to perform field tests to assess the waterhammer (pressure surge) transients. Surge pressure measurements were taken after an induced pump power loss and subsequent check valve slam. They also developed a computer model to see how well available software could simulate the produced transients. This data was gathered to provide guidance to the municipality on future project work.

Minimizing Maintenance Costs by Right-Sizing Dry Weather Pumps

Overview: The Norchester Pump Station was rebuilt in 2016 with dedicated dry weather and wet weather pumps. Between 2016 and 2018, the dry weather pumps required more than 5,000 hours of labor and $20,000 in parts for corrective maintenance due to pump ragging and pump failures. These pumps were replaced with smaller, properly sized pumps in late 2018 and have operated without significant issues since saving time and labor and increasing the reliability of the station.
