In the maintenance of municipal facilities, early detection of changes is crucial. At the City of Ellwangen, SIPREMA is used to achieve exactly this—without additional sensors and without complex integration into existing systems.

During live operation, changes in the acoustic behavior of machines were reliably detected. Signals that previously required experience and careful listening are now made continuously and objectively visible. This allows maintenance measures to be better prioritized and unplanned interventions to be avoided.

“By detecting faults—or what may lead to a fault—we can react to incidents at an earlier stage. This also saves costs, for example when a bearing failure in a pump is starting to develop,”
says Hubert Traub, Plant Manager of the wastewater treatment plant.

For the local team, it was particularly important that the acoustic condition monitoring integrates smoothly into everyday work. SIPREMA complements the experience of maintenance staff with an additional digital layer of perception, supporting well-founded decisions in daily operations.

This practical example shows how acoustic condition monitoring works in real life: pragmatic, easy to understand, and with tangible benefits for maintenance.
