System Alerts
Please be advised that due to a continued period of dry weather, the Latrobe Municipal Authority (LMA) is increasing pump speeds to our distribution system in order to restore water levels in storage tanks throughout the system.

As a result, customers may temporarily experience dirty water.

If you experience dirty water, please consider flushing with cold water until clearing occurs.

We apologize for the inconvenience and appreciate your patience during this time.
