SCAM ALERT: Recently calls from an unknown source have been made to WMU customers indicating that their account is delinquent and that payment must be received within 45 minutes in order to avoid a disconnection of service. These calls are NOT from Willmar Municipal Utilities. It is not the practice of the utilities to make threatening calls with such an immediate payment time. Should you receive such a call please contact Willmar Municipal immediately in order to avoid falling prey to this scam.
