Our water storage tanks are made with high-density polyethylene (HDPE) that is resistant to UV rays and corrosion. Available from 500 to 75,000 L.

What is a water storage tank?

HDPE tanks for underground storage of liquids

Our rotomoulded water storage tanks are manufactured with 100% virgin high-density polyethylene (HDPE) that withstands weathering thanks to its resistance to ultraviolet (UV) rays.

This level of quality makes our tanks suitable for contact with products meant for human consumption.

We manufacture a wide range of tank models, both for above-ground and underground storage. Storage capacities range from 500 to 75,000 L, depending on the selected model.

Our underground tanks up to 15,000 L are made in one piece. For larger models, tank 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 welding.

Within our range of surface tanks, we even have a product specially designed to pass through doors with a maximum width of 680 mm.
