What is a water storage tank?

HDPE tanks for underground storage of liquids

Rewatec tanks are manufactured using the rotomolding technique with 100% virgin high-density polyethylene (HDPE). The material used is of a quality suitable for contact with products for human consumption and is resistant to ultraviolet rays (UV), in order to last unalterable in outdoor conditions.

We manufacture a wide range of water tanks, both for above ground and underground storage. If you need a surface model, we have multiple solutions for any type of need. Vertical and horizontal tanks, and even a model specially designed to pass through doors with a minimum width of 680 mm.

Underground models up to 15,000 litres are made in one piece. For larger models, the joints are welded internally and externally and mechanically reinforced around the perimeter. For complete safety, a leak test is carried out on each joint after completion of the welding.

Storage capacities range from 500 to 75,000 L depending on the selected model.
