Several residents have reported strange phone calls about water testing in their homes so New Braunfels Utilities is cautioning its customers that there may be a scam in the works since the people ask to come outside of business hours.
"That kind of raises some concern whether their drinking water is okay," said NBU Communication Manager Gretchen Reuwer. "Many of them have agreed, but once they do that, they start thinking about the time in the evening that these people want to come in, and they know that NBU has regular office hours," Reuwer said.
