Unfair Utility Billing Concerns

I spoke with my property manager, and she stated we have a shared meter. Also, I was charged at commerical rates instead of residential rates. So, my water bill for one month was $*. Is this legal in Colorado?

Do you think I can take legal action even though my lease states I have to pay for all utilities and I can not request for a reimbursement? What's a PUC?

Food spoilage or any other damage to Tenant’s personal property due to failed electrical or appliances will be at Tenant’s expense and not Landlord’s expense. "

Yeah even though it states all utilties it does not clarify the usage or shared meter
