Due to the extreme cold conditions of this winter, residents of the city are advised to test the temperature of their drinking water. If the temperature is below 40 degrees, it would be advisable to run water continuously to avoid water pipes from freezing. In order to properly test your water, run water continuously for approximately three minutes and then insert a small thermometer that is typically hung in a freezer or used in an aquarium. Running water with a stream the diameter of a pencil lead is generally sufficient to avoid freezing but, the farther your water temperature falls below 40, the stronger the stream needs to be. Once the water temperature falls below 40, it is likely that you will need to run that water until the ground thaws in the spring. If you have any questions, contact Brian Burkholder, Water Superintendent at 507-867-3810.
