City of Buchanan issued the following announcement on Oct 2.
HYDRANT FLUSHING - OCTOBER 5-7
The City of Buchanan water department will be flushing hydrants October 5-7 as part of our regular maintenance process. During and immediately after this process, you may want to avoid doing any laundry or excessive use of hot water as there can be some discoloration.
If you experience dark or cloudy water, it's best to run COLD water through your bathtub faucet, an outdoor spigot, or flush the toilet until the water runs clear. Kitchen or bathroom faucets are not recommended as sediments may clog the screen filter. Using hot water will pull the discoloration into your hot water heater and take longer to flush out.
