Cold Weather

If you live in a region that receives significant freezing weather in the winter, you may be concerned about storing rainwater. However, with proper planning and construction, you may have nothing to fear. Usually the most vulnerable location that is prone to freezing is the piping. Be sure to wrap any exposed piping in insulation and when possible bury them below the freeze line. It may also be helpful to plan for a "dry-line" system which has no standing water in the pipes. Valves, pumps, and treatment equipment should be protected in a pump house or insulated box. As for the tank itself, round tanks with straight sides do better than round tanks or corrugated sides. Insulation around the tank can be used in extremely cold regions, and you must make sure that the roof can handle a heavy snow load.
