Xylem’s wastewater pumping solution to substantially reduce energy use at Australian pump stations

Xylem Inc. has been working with water and sewerage services provider Unitywater in Queensland, Australia to significantly reduce energy consumption and eliminate blockages at a number of Unitywater’s wastewater pump stations.

Unitywater is one of Australia’s largest water services providers, servicing over 16 percent of Queensland’s population with 17 wastewater treatment plants and 778 sewage pumping stations.

Xylem and Unitywater piloted the revolutionary Flygt Experior wastewater pumping solution at the Bli Bli sewage pump station near Maroochydore. This initial trial resulted in a 57 percent reduction in energy consumption compared to the original pumping equipment. After an additional six similar trials at other Unitywater wastewater pumping stations throughout Queensland, Flygt Experior has provided substantial reductions in energy use and pump blockages. Unitywater is currently evaluating where to install the wastewater pumping system to improve operational reliability across their wastewater pumping network.

Unitywater Executive Manager for Infrastructure Services Glen Babington said, “The equipment at this trial site resulted in significantly fewer blockages and service call-outs, helping to reduce its running and maintenance costs. Such savings have the potential to help us keep cost as low as possible for our customers.”

Xylem’s Flygt Experior solution is specifically designed for wastewater pumping, combining N-hydraulics, premium efficiency motors and intelligent controls to deliver reliable, clog-free and efficient wastewater pumping.
