Kingsport Residents Could See A $7 Monthly Increase On Utility Bills Starting Next Fiscal Year. The Proposed Hike Covers Water, Sewer, And Stormwater Services, With Most Of The Funds Going To Replace Aging Infrastructure And Meet Environmental Standards. Officials Say Old Galvanized Water Lines And Stricter Regulations Are Driving The Costs. The Plan Calls For A $2.51 Water Rate Increase, $4 More For Sewer, And A 50-Cent Rise For Stormwater—The First Since 2011.
