Non-pressure underground water tanks

Drinking water tanks. Fire-fighting water tanks. Rainwater tanks.

In our range of underground tanks we offer single-walled tanks for drinking water, rainwater and fire-fighting water, as well as other liquid media.

Metal Zbiorniki is a manufacturer of drinking water tanks. Our underground tanks are used both for storing drinking water and for balancing temporary fluctuations resulting from changing water demand. In addition, the tanks can be used as fire-protection water tanks and as tanks for storing excess rainwater.

Our tanks hold a certificate from the Państwowy Zakład Higieny (PZH). The tanks are protected against corrosion on both sides. The internal surfaces of the tanks that come into contact with drinking water are protected with coatings certified by PZH. The external surfaces of the tanks are coated with a special heavy-duty polyurethane primer enamel suitable for underground installation.

We manufacture tanks based on our own documentation or documentation provided by the customer. Our underground tanks can be installed, depending on soil and groundwater conditions, on a foundation set into the ground, on a compacted sand and cement base, or on an embankment in the ground. Our underground tanks are most commonly cylindrical with a horizontal axis, closed with convex end caps in accordance with standard PN-EN 12285-1.
