My Charlotte Water Bill is...$7300?

Hi all, seeking any and all advice (and perhaps validation) for this issue. I woke up to an automated email about my water bill and checked it as I always do just to make sure all was well.

All was not well. Charlotte Water claims I have used what amounts to $7,284.90 in water in my last billing cycle.

The city came out last month and fixed a pipe in my front yard, so I thought this was related. But I called, and they tell me all looks good on their side and my meter now. They told me my next course of action is to hire a plumber to come out and make sure the issue is not on the private side, so I'm doing that.

Look, I get it: sometimes your private residence springs a leak, and you don't find out until you check your bill. That's what rainy day funds are for. But is this even close to believable? Even if I did have a leak, could it have really wasted thousands of gallons of water without me noticing any water pressure issues, pools of water, or anything else wrong?

I'm just posting to see if anyone has had an issue even remotely close to this, and if I should proceed differently. Thanks for your time and consideration!

Edit for Update:

Thank you all for some good advice, helpful tips, and even some of you for expansive knowledge of this topic! The plumber found nothing and put that in writing for me, which triggered the city to escalate the case. They'll be sending a supervisor to assess what's going on and my account has a delinquency protection for now.

I never expected so many of y'all to care about my water. These comments definitely made me calm down a bit. Y'all are great. Charlotte's got a lot!

UPDATE 2:

Hi all, thanks again to everyone for sharing their experiences and offering their advice over the past week! You all had some outstanding advice and knowledge to keep me sane. I've also read some disappointing stories, some far more than a simple error on an account statement. That said, many of you have also asked for an update and I suppose I'll thank my lucky stars as well as the community here.

A supervisor from Charlotte Water came by for all of about seven minutes and basically said yeah, this is ridiculous. He checked the meter, parts of my property, and had made the assessment that this was clearly an error before I even got to answer the door. It almost seemed like he was annoyed that they sent him out for this anyway, especially in the cold! He told me that the high usage is likely related to the busted main that they fixed by the street, and that they will get my bill reduced to an average of the past three months before the errors.

This seems to be the best case scenario. I'll believe it when the new bill comes across, but seemingly common sense prevailed here. I know that's not the case for everyone who posted here, but keep fighting the good fight. I'm thankful to the community for helping me keep my peace of mind. I'm going to come up with some sort of idea to give back, especially if the previous "slightly higher" bill I already paid gets credited. I can't pay all your water bills but I'll find a way to contribute back to this community! Thank you again!
