Retention tanks

are used in the retention of rainwater, gray water, domestic sewage and slurry.

These products are made in the form of a cylinder with a horizontal axis. They are made of a two-layer, spirally wound SPS structural pipe. Equipped with a tight manhole chimney and a gravity ventilation system. These tanks can be produced in any colors, diameters from 600mm to 3500mm and circumferential stiffness SN2 to SN16. We adapt the tank parameters, i.e. volume, length, diameter and peripheral stiffness, to the customer’s needs. In the case of large capacities or specific requirements from the ordering party, it is possible to connect the tank batteries in series or in parallel at the construction site.
