The Oneonta Department of Public Service will be flushing water mains in the high service area starting today. Work hours are between 9:00 a.m. to 4:00 p.m. and the first round of flshing is to be completed by the end of the week. Officials say that during flushing there may be a change in water color, pressure and/or loss of water. This is a common, temporary occurrence and is not a cause for alarm. Running all cold water faucets in the home should remove any discoloration.
