Adapter ring on manhole cone

Sewer manholes in roads have a lot to put up with. They are exposed not only to vertical, but also to horizontal loads. For this reason, newer types of manhole cover are secured against lateral displacement. However, older types of manhole, with no such security, are still predominantly found in roads. For these, there is now an adapter ring available that is claimed to prevent displacement. IKT has tested this…

Municipalities are therefore obliged to provide timely information and advice to site owners on both technical…

Pressure sewer pipes are well down a sewer operator’s list of their favourite parts of the network. Because there are no inspection or maintenance ports. Because the precise location of the pipe is often not known. Because numerous bends obstruct the flow. They can be found in practically all drain and sewer networks, but their characteristics and their special design confront sewer network operators with a real challenge when it…
