Scams are on the rise in the Bay Area this holiday season, reaching people through text messages, phone calls, and even knocking on front doors.
Scammers are even posing as law enforcement and utility workers to obtain people's information.
"Customers are telling us that people are coming to their front doors, knocking on their doors, letting them know they are water agency employees and are there to test their taps," said Andrea Pook of the East Bay Municipal Utility District.
In the past few days, the utility said it has gotten over 40 calls from customers about the scam, primarily in Richmond and Oakland.

"We do see this around the holidays, and people should be careful," said Pook.
