FLOU Water Tanks

Our water storage tanks can be used in many applications, including rain harvesting, irrigation, livestock agriculture, food preparation, drinking water and so much more.  FLOU tanks are made from FDA-approved potable water-safe, food-grade plastic and are produced to the highest quality standards.

FLOU water tanks come in a variety of vertical Polyethylene tanks, in many shapes and sizes.  They are made with a black food-grade inner layer molded in to prevent light penetration and inhibit algae growth to keep your water as fresh as possible.
