Failing water meter batteries continue to cause a steady drip of inaccurate water bills for Harrisburg residents. The Harrisburg Authority are juggling repairs with upset residents who are being overcharged.Every time the faucet is turned on, it costs moneymost know that much. But what many Harrisburg homeowners may not know is that their estimated reading on their water meters are resulting in inaccurate monthly bills.In November, The Harrisburg Authority (THA) took control of the city's water and sewer systems as a result of the court-approved recovery plan. The billing still runs through the City Treasury for the time being. Also in November, THA presented to city council some issues regarding failing water meter batteries. At that time, it was estimated that 6,000 batteries needed replaced in Harrisburg.In November, abc27 spoke with Thorin Burgess about his estimated water bill. Burgess said after nine months of a low or zero balance his bill jumped to $998. Others tell abc27 their bills went from $90 a month down to $9. One resident said they received a credit for being overcharged at times.THA Executive Director Shannon Williams said replacing the batteries has been a slow process due to this winter's weather, focusing on water main breaks and overall transition. According to THA's January report, 160 batteries were replaced. However, the report said of 21,696 attempted meter readings in Harrisburg, 12,937 returned back with readings, and 18 meters were missing.Williams said the majority of the problem stems from dying batteries. Most of the water meters were installed in between 2000 and 2003 using a battery with a 10-year life span. Williams said the city did little upkeep and maintenance over the years. Currently, THA workers are noticing more than just failing batteries.
