The major cause of freezing is settling of the two inch pipe that pumps to the drain fields which causes back flow to settle in the pipe instead of going back into the pump station. Most contractors install a 10 foot 4 inch sleeve and use a more rigid pipe to prevent this. Other causes are too little water use since sewage heats the drain field. High water tables which slow down percolation into the ground. Also running sump pump water, humidifier water or dripping faucets. The best way to prevent freezing is to put straw over the drain field and the pump station pipe.
