These water tanks are rotationally molded into a one-piece structure, with no seams, joints or welds to cause leaks. The polyethylene resin is made with UV inhibitors to keep these tanks in working condition for longer. The resin is also FDA approved, which means you can use these tanks to store fresh potable water. The green and black tanks are more effective at blocking out sunlight which limits algae growth. These tanks are equipped with tie-down slots and built-in measurement indicators. These tanks are designed to only store water. This is a 1.0 specific gravity tank.
