For transporting seawater, 275-gallon Intermediate Bulk Container (IBC) totes are excellent vessels. If you’re buying a used tote, make sure it was previously used for food-safe purposes or has a new bottle.

To prepare the tote for seawater, leach it with fresh water for 24 hours, and the first load of seawater should also be discarded after a similar leaching process. To expedite filling and emptying the tote, a hatch should be cut into the top–this allows for inserting a high volume sump pump directly into the tote. The pump linked is not rated for saltwater to reduce cost–after each use it needs to be rinsed thoroughly by running fresh water through the pump to clean corrosive material from the pump.
