All RPU customers urged to monitor the temperature of their water

Friday, January 28th, 2022

January 26, 2022 – ROCHESTER, MN – Rochester Public Utilities (RPU) is starting to hear from customers that are concerned about their water service freezing this winter. Current frost depth is 36” as of January 26th.

RPU advises these water customers to take the temperature of their water and then continue monitoring it until the frost is out of the ground. This is especially important for customers that have experienced frozen water services in the past. Run an inside cold tap and hold a thermometer in the stream for 10-20 seconds for an accurate reading. If your water temperature gets below 35 degrees Fahrenheit, you should immediately start running a continuous pencil-width stream of water from a faucet.

All businesses and residence types could be affected. The age of your home does not matter.
