The manholes are made of PE material and are compatible with polyethylene sewage pipes.
They are made with technology of rotomolding or manufactured from KONTI KAN SPIRAL PIPE. Either one of these technology to be used, manholes gave compact sewage system.

TYPES OF MANHOLES:

  • Standard manholes
    This kind of manholes is situated centrically above pipe. Because of static and safety reasons this type isonly recommended if the diameter of the pipe is smaller or equal to the diameter of the manhole. They can be with two or three inlets.
    Normally the diameter DN800 of DN1000 is used for base of this kind of manhole.
  • Tangential manhole
    This manhole is situated tangentially to the pipe, which means displaced from the middle. That is the reason why by using this kind of manholes with the standard diameter of DN 1000 it can be also used by pipes with higher diameter.
  • Special manhole
    If it is necessary special construction of manholes (non standard), then the manholes can be manufactured from KONTI KAN SPIRAL PIPE, inlet and outlet from KONTI KAN pipes.

Standard
Valid standard for fabrication, static calculation and installation of manhole are EN13598-1, EN 124: 1994 and EN1610

Fittings
Manholes can be very easy connected to pipes with whole range of different fitting fabricated from KONTI KAN Pipes.

All these manholes are produced in hights according to the customers demands and have special designed polyethylene manhole covers.
