Manholes - Peštan


A special segment of production at Peštan are revision and drain manholes. Peštan manufactures manholes, with or without a settling tank, as an integral part of the collectors in gravity systems of wastewater, rainwater or mixed water. Standardly made of polypropylene. The product range of Peštan company has included drain manholes. These products are mainly intended for the collection of rainwater in the rainy sewage systems in individual household installations as well as in systems engineering (collecting rainwater from roads).

  • Manholes

    Manholes are manufactured as a monolithic structure made up of a flat bottom, manhole body (PP corrugated pipe) and connections to a specification projects. Ports and body are mutually welded by extrusion welding. In the same way, the bottom of the manhole is connected with the body of the manhole. Peštan revision manholes are an integral part of the collectors in gravity systems of wastewater, rainwater and mixed water. They are used as revision manholes, manholes  to stop the fall (cascading manholes) or manholes with sedimentation trap for flushing sewers.

    Manholes are made to order / project specification. Diameter of the manhole is DN 800 mm, the height is up to 6m. The diameters of input / output connecting pipes are up to DN 600 mm.

    Drain manholes – drain shafts

    Our production range has included drain manholes manufactured with a flat bottom or gutter at the bottom. Manholes with flat bottom are made of corrugated pipes and in the following diameters:

    a. Drain manholes ø315
    b. Drain manholes ø400

  • Physical properties of materials

    The physical properties of the material from which the pipe of the manhole is made of can be viewed in the corresponding section of corrugated PP or PVC pipe (not link the PP corrugated pipes and PVC pipes)

    Chemical resistance of materials

    Whether it is a shaft made of corrugated pipes or PVC pipes, table of chemical resistance of materials you can find in section Download.

     Connecting manholes and pipes

    Whether a revision or drain manhole, the points of contact with the pipes on each Peštan manhole have a socket, which must be appropriate to insert the pipe, a water resistance is achieved through the sealing rings made of EPDM rubber (EN 681), which are either assembled on pipes (corrugated pipes) or inserted into sleeves (smooth tubes).

    Installation, jointing pipelines with manholes and testing of the system is done according to applicable European standards – EN 1610th
