Battery tanks Weholite Uponor Infra

Multi-purpose tanks

Multi-purpose polyethylene tanks for water, sewage and other liquids


One of the most typical products manufactured by Uponor Infra is universal polyethylene tanks, which are characterized by high quality, offer a wide range of capacities – that may be adapted to the individual needs of the ordering party – and are available in inner diameters ranging from 1000 to 3000mm. The tanks may be of ring stiffness ranging from SN2 to SN8 (PN-EN ISO 9969), which helps adjust the parameters of the tank construction to the specific water and soil conditions of a given project. What distinguishes Uponor tanks from other tanks on the market is their wall (structurally based on a dual layer Weholite pipe), the unique construction of caps and the fact that they may be tailor-made for a given project.

Tank batteries of any capacity


A typical tank is a single-body structure, but there is a possibility to join tanks into batteries of any capacity. Large capacity tanks (up to even over a dozen thousand cubic meters) are delivered in sections that are ready to be joined by extrusion welding. Consequently, the final product is a monolithic construction that is free of mechanical joints and guarantees maximum water tightness and reliability. Such a solution enables the installation of large capacity tanks with the optimum use of the available terrain.
