Our facilities are made for winter temperatures in the 40’s and 30’s but when the temperatures dipped to 17 to 19 degrees for three nights we were on the alert. We were stuffing more and more blankets into shelters, particularly for those who live in a shelter alone and adding heat lamps and heating blankets for those particularly at risk. All of our water was frozen in the morning including that to our houses. Luckily breeding pigs had enough water in the pools that the ice could be broken up and water released. The automatic waterers and the large black water bowls were out of commission. Once it began to thaw a bit the pipe breaks began to spray water everywhere. All told in the three days we probably had 30 or more broken pipes and some at our Annex as well.
