Bigger operations require big storage tanks. For the hobbyist, sterilized plastic garbage cans are sufficient. You can determine how much storage space you will need by allowing two gallons per tap. For example, if you have fifteen taps, a thirty gallon garbage can is sufficient most of the time. If commercial tanks are used, the massive weight of the sap must be considered. Significant thought should be given to the support of these tanks. A 250 gallon tank will weigh almost a ton with a full load of sap. A ton will require more support thank two 2x4's.
