A dilapidated steel pipeline frequently in need of repair was located in an ecologically sensitive area which has meanwhile been reclassified as an FFH site. In order to avoid further disruptions due to repair work, the old pipeline needed to be replaced without disturbing the biotope and without going in with heavy equipment. Nowadays tasks of this kind are solved very elegantly with ductile iron pipes which are pulled in by means of the single pipe assembly HDD “nonimpact” process.

The pipe landscape all over the world is changing. Pipe materials have evolved from grey cast iron and lead into today’s ductile iron, steel and plastics (PE and PVC). Yet it is plastic pipes that have produced the most exciting developments, and possible solutions to longer term issues like leakage, environmental impact and whole-life pipe performance.

Simply for geological and topographical reasons alone, the renewal of a drinking water transport pipeline in the densely wooded region of the Western Ore Mountains is no straightforward undertaking. Thanks to modern piping systems with their highly developed structural design methods, joint technologies and corrosion protection techniques, projects of this kind can be handled without problem. In the case illustrated here, the planning engineers were confronted with a fairly unusual additional challenge in the form of the soft, unbuffered water in the reservoir which, in conjunction with the cement mortar lining of the pipe, can be subject to an inadmissible increase in its pH value in stagnation phases. By using a proven method, endorsed in the DVGW regulations, of applying carbon dioxide gas under pressure in individual sections of the pipeline before acceptance and commissioning it was possible to ensure that the drinking water in the “Auer Ring” always meets the directives of drinking water legislation.

Many large interceptor sewers, predominantly installed under public roads, have been in use for over 100 years. They are made of brickwork or compressed concrete and often show serious damage, so that it would seem that long-term stability can no longer be guaranteed. As an alternative to replacing large profiles, various renovation procedures offer significant advantages with respect to investment costs, environmental protection and urban pollution. Depending on the procedure, it may well be possible to extend the service life, in order to match that of a replacement. However, beforehand, an in-depth study of the current stability and residual load capacity of the existing sewer is required, along with needs-based selection and dimensioning of the rehabilitation procedure. The new standard DWA-A 143-2 serves as a good basis for the necessary static calculations.

E-Power Pipe® is a trenchless method for the economic and environmentally friendly installation of underground cables. The new development from Herrenknecht has been nominated for the bauma Innovation Award 2019 in the "Machine” category. Trenchless technology offers significant advantages over the conventional open-cut method. The innovative procedure closes a technical gap because it allows small diameter drives with ten times greater lengths, shallower depths as well as high precision and speed.
