My sewer bill. Water/sewer are billed together. Last year, I paid ~$135/month. Last month, it was $406. Water is $1.61 per 1000 gallons and Sewer is $2.35 per 1000 gallons, plus a service charge for sewer and other miscellaneous taxes.
The Sewer Authority was sold about 5 years ago and the new owner is charging usury fees for it.
