Municipal sewer tanks - Uponor Infra


Weho tanks offer a wide range of capacities

One of the most typical products manufactured by Uponor Infra is the universal polyethylene Weho tank. It is characterized by high quality, and offers a wide range of capacities that may be adapted to the individual needs of the ordering party. The Weho tanks are available in inner diameters from 1000 to 3000 mm. The tanks may be of ring stiffness ranging from SN1 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 Weho tanks from other tanks on the market is their wall (structurally based on a dual layered Weholite pipe), the unique construction of caps, and the fact that they can be tailored for any given project.

The advantages of Weho tanks

  • Double-layered walls and welded joints guarantee a 100% leakage proof operation and long-term durability
  • Non-toxic
  • Foundation in difficult soil and water conditions possible
  • Installation in roads and underneath car parks
  • Total resistance to corrosion and high resistance to chemicals
  • Long storage with no loss of parameters (UV resistant)
  • Low weight, quick and easy to assemble (also in winter conditions)

It is also possible to install fittings, technological devices, and other equipment inside the Weho tanks. Pressureless atmospheric tanks may be installed over or underground, or may be partially embedded in soil.

A typical Weho tank is a single-bodied structure, but there is a possibility to join tanks into "batteries" of any capacity. Prefabricated tanks delivered as one component may be of capacity 2-90 m3 (larger capacities are manufactured on demand and transported on individual conditions). The maximum length of the delivered tanks is only restricted by transport limitations.

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 watertightness and reliability. Such a solution enables the installation of large capacity tanks whilst optimising the use of the available terrain.
