    Manholes

    Our manholes complete our range of high-quality system solutions. Public authorities are increasingly focusing on manholes for wastewater systems. For a number of reasons, wastewater today is considerably more aggressive than it was a few years ago. The main cause of this is changes to social demographics. In addition, wastewater today has to be transported over greater distances. For treatment plants to work efficiently, it is crucial to avoid unwanted water infiltrating into wastewater systems through insecure manholes. 

    Standard manholes come equipped with a one-piece PU bottom element with integrated manhole connections from DN 150 to DN 400 in the pipe wall, as well as integrated buoyancy protection.

    Construction features

    • KERA.Port manholes are monolithic up to transport height 
    • Extension pieces are delivered with integrated joint
    • Cover slabs complete the manhole; for DN 1000 manholes, an optional taper is available
    • The corrosion-resistant inner lining of channel elements/cover slabs/ tapers is made of polyurethane (PU) up to DN 1000
    • Structural analysis allows a possible installation depth exceeding 8 meters, documented with heavy traffic loads. Furthermore, the manholes are approved for installation within the range of railway traffic
    • With their rigid, non-deformable material, the manholes are absolutely secure and won’t buckle
    • Manholes with nominal sizes DN 600, DN 800 and DN 1000 are equipped with a PU bottom element as standard
    • Delivery includes the manhole base unit, extension pieces and cover slab or taper
