Extra Charge on Water Utilities?

I got my water bill due for December and it was 152% higher than normal…

I looked at the bill details and there’s a $175 charge for ‘10/15/25 Mand Serv’. Seems like it stands for mandatory service.

I never had anyone out to my property. I’ve also been paying Boynton Beach water bills for nearly a decade and never seen this.

I’ll give the department a call tomorrow but has anyone seen this or can tell me what it’s related to?
