Pipeline replacement using relining

Mark Heathcoate, Plastics Industry Pipe Association of Australia

Relining of old pipeline systems is becoming an increasingly attractive option to asset owners and operators as an effective alternative to open trench replacement. Relining options rely predominantly on plastics pipe systems for their success. These trenchless options utilise the existing pipeline and as the name suggests minimise the excavation or trenching required.

Curing elderly pipes in the retirement capital

As New Zealand’s leading installer of Cured in Place Pipe (CIPP), PipeWorks has delivered the majority of sizable and challenging CIPP projects throughout the country in the last five years.

Save time and money with Patch-A-Pipe

When Sideliner began operations eight years ago the only option was to excavate corrupted small diameter pipelines. As is often the case with new technology there was no market for pipe lining. Seeing the potential for a small diameter pipe lining system, Sideliner embarked on developing systems to eliminate the need to excavate, and in doing so, developed a market in this area.

Structural Pipe Rehabilitation-Compact Pipe

By Bernd Vetter

The rehabilitation of existing pipelines within South East Water’s reticulation network by use of the close-fit lining technique known as Compact Pipe, promises to deliver substantial benefits by completing the job faster, at lower risk and with the least impact on the environment and public.

Testing of junction seals shows long life expectancy

While deteriorated pipelines can now be structurally renewed by a variety of lining technologies, it is universally recognised that a separate operation is needed to provide secure, water-tight junctions.

New specialist Trenchless Technology contractor announced

Last December, the formal execution of a number of agreements by the shareholders associated with the establishment of a specialist Trenchless Technology contracting company, Premium Pipe Services Pty Ltd, was completed and the company commenced operations as a specialist pipe line services company and a one stop No Dig Trenchless Technology contractor.

Effective root control programs

In order to achieve targets relating to sewer collection asset performance it is essential to develop an effective overall strategy that will deal with different problems, such as root intrusion, that inevitably occur.

Rootfoam provides a preventative solution

Rootfoam prevents the regrowth of tree roots and entry into sanitary, sullage, septic and stormwater sewers following mechanical clearance.

What are you doing about tree roots in your sewers?

RootOut® is a form of stand alone chemical root control, which avoids many of the problems associated with older forms of root control, and has its own unique benefits.

A trenchless assessment guide for construction and replacement of underground utilities

John Matthews and Erez Allouche

When decision-makers try to select the optimal trenchless construction method for installing or replacing underground utilities, they are often overwhelmed by the large number of methods and attributes that one needs to consider as part of a comprehensive analysis. The Trenchless Assessment Guide (TAG) provides users with suitable construction options for a range of situations.

Nordipipe used in Taiwan watermain rehab program

Every laid pipe can be damaged due to ageing, ground movements and many other common reasons. Typically, this has been manually repaired or conventionally replaced. However conventional methods can be very costly and time consuming, on top of safety and environmental issues that may arise.
