The product consists of a Tank with a capacity of over 3000l, a telescopically applied revision and its extensions and covers. The inflow to Tank can be made with a sewer pipe with a diameter of 110 or 160 mm.

The design of the revision, allowing its adjustment, allows to align the differences between the terrain level and the completion of Tank. It is produced as a monolithic polyethylene by rotational molding, thus providing impermeability of water and sewage, mechanical resistance to soil load, decompression, impact and resistance to aggressive substances in sewage, temperature changes and full stability in the ground.

Additionally, thanks to the ribbed construction, they are characterized by high structural strength. The dimensions of the Tank allow its assembly on small plots. In addition, the installation due to light weight is possible without the use of heavy and expensive cranes. They are an ideal solution for use as pumping wells, water meter shafts, drainless tanks.
