The BlueBox Combo storage system is a foldable, fully enclosed water storage solution. It’s designed to prevent contamination from rust, dust, mold, rot, insects, animals, and airborne bacteria. The system is easily transportable and deployable without preparation. Its inner liners are made of food-grade LDPE, compliant with EU regulations. The tanks can be connected serially, both horizontally (up to five tanks) and vertically (up to three tanks), allowing for adjustable volumes and a common fill/discharge point.
