Covington homeowners surprised by their unusually high stormwater utility bills this month are advised to call the Covington City Hall. According to Bobby Johnson, system information manager for the city of Covington, of the 5,400 stormwater bills sent out this month approximately 3,000 bills were affected by a software glitch which did not factor in earlier paid credits to accounts. Homeowners who elected to pay half of their yearly stormwater utility bill in July would not have seen the credit added to their account in November.
