Republic Services found a system glitch in its financials that only notified and implemented the annual percentage increase (PI) for approximately half of the Fountain Hill Residents. This is an annual recurring PI of 3.5% that was set to go into effect January 2023. This annual increase is contractual and has been occurring since the beginning of the contract in 2019. The missing PI for half of the Fountain Hills residents was caught in March 2023 and implemented at that time which resulted in a back bill for the 3.5% for the two months that service was provided.
