Challenge
The city’s aging Gilman Avenue Lift Station was the first of 12 stations to be upgraded as part of a capital improvement plan at the city’s wastewater treatment plant (WWTP). The new Gilman duplex station was designed as a prototype to achieve higher capacity, reduce energy use, and establish a cellular-based Supervisory Control & Data Acquisition (SCADA) network at the WWTP.
Solution
For the upgrade, city engineers selected two Xylem brand model 3127 Flygt N-pumps, based on their energy efficiency, clog-resistant features, and adaptability to the 11 additional lift stations slated for eventual replacement. Flygt representatives worked with plant engineers to reduce pump horsepower ratings from 12 horsepower to 11 horsepower, keeping the equipment within budget while still delivering the desired performance curve.
