Drainage system for heat and power station, Gdynia, Poland

Drainage system for heat and power station

The heat and power plant in Gdynia struggled with choking drainage ducts and the resultant elevated level of ground water, which would lead to flooding of the underground levels of the facility. The construction of a classic drainage system using excavation methods was seriously challenged and even impossible in many places due to collisions with numerous underground systems as well as the protective zones of overhead power lines. As a result, a decision was taken to build a new drainage network in the trenchless technology with the use of jacking drainage VipLiner DN630mm modules from Uponor Infra.

VipLiner jacking drainage module VL-PD DN630mm L=1 m with cross-axial slots (240 slots of 150x1.5mm) – 895 modules

VipLiner drainage modules feature solid polyethylene (PE) pipes with smooth inner and outer surfaces. Due to their strength characteristics, special technology and geometry of their outer layer grooving, the modules can be used for trenchless drainage systems which lower the level of ground waters. VipLiner 1-metre drain module have slots made using a water jet cutter. 240 slots of 150mm x 1.5mm in size are spaced in perpendicular along the axis. Their cross-section has a wedge shape, with the narrower opening at the inner surface. Such cross-sectional geometry creates a natural reverse filter, ensuring that the soil surrounding the drain pipe is not washed away.

This world-first method is innovative and patented!

Slotted drainage VipLiner module has been awarded the TYTAN 2016 Award in the ‘Product of the Year’ category during the XIV International Conference "Trenchless Engineering" in Krakow.

 The district cooling system in Helsingborg involves the streamlining of current production. By means of seawater and using heat from the district heating network to power an absorption cooling unit, district cooling provides much better environmental values than electric cooling units. The district cooling station is an efficient source of cooling for buildings, industrial facilities and shopping centres.
