A manufacturer of wastewater/storm water processing equipment developed a new flexible auger system to transfer solids from wastewater. The new system helped to automate what had been a labor-intensive procedure. But the flexible auger was sometimes housed in unheated buildings in cold climates where freezing is an issue, especially since the equipment is used intermittently. Without freeze protection, the system could potentially have problems on start-up.  Systems range between six and thiry feet.
