Scammers on Hawaii Island are posing as water department workers and demanding cash for fake overdue bills.

• The County of Hawaii Department of Water Supply says people claiming to be its employees are showing up at homes asking for cash.
• Real water department workers never show up unannounced to collect payments.
• Actual employees drive marked vehicles and always carry ID.
• Anyone approached this way should refuse to pay and report the visit to the water department.

Outlook: Expect more of these door-to-door scams as long as they keep working, so treat any surprise demand for cash as fake.
