Safety Measures for Reducing Asset Strikes

With the rapid expansion in HDD use, there has been a responding increase in safety incidents. 3rd party safety issues, in particular damage to crossing utilities in the bore path, will become a much bigger issue for drillers. Utilities and lead contractors are becoming more focused on this issue and liability issues…

The Economical and Environmental Benefits of Slurry Waste Handling

Improper handling of HDD slurry waste and construction fluids can result in operational downtime, expensive disposal costs due to liquid waste hauling and a negative environmental impact. BOS Solutions specializes in on site, solids and liquid separation of any mud or slurry type. By utilizing our new technology and…

Trenchless Technology Used to Understand Risk Under New Major Road

Managing buried assets and risk is becoming more optimised with the advent of trenchless technologies to assess their condition. The Queensland Department of Transport and Main Roads has recently utilised innovative technologies and techniques to help understand the condition of a critical buried water main, to assess…

Trunk Main Rehabilitation using a Kevlar Reinforced Composite Lining System

The paper presents a flexible Kevlar® reinforced lining solution for the trenchless rehabilitation of critical water main infrastructure. The paper will show the composition of the lining material as well as the functionality of the specifically developed termination fittings. The lining material is characterized by…

Using GPR technology to increase safety and reduce equipment damage and site risks

This paper will highlight the new advances in Ground Penetrating Radar (GPR) technology and software processing which complement traditional Electromagnetic (EM) utility locating methods. GPR allows for mapping of abandoned utilities as well as metallic and non-metallic utilities. Using case studies, we will show new…

Using the Versatility of the CIPP System to address challenges

It is a well-known fact that Cured in Place Pipe (CIPP) Lining is a trenchless methodology for the rehabilitation of deteriorated pipes and that it can extend the design life of the rehabilitated assets by at least 50 years. But the CIPP system is much more than that. There are wide choices of resins with different…

”Why Clean Clean Pipes ?” Sydney Water Trial of SL-RAT

”Why Clean Clean Pipes ?” Sydney Water Trial of SL-RAT The SL-RAT is a new innovative technology introduced to the Australasian market by Austeck Pty Ltd in 2014 and developed by Infosense Inc in the USA. The SL-RAT sends an acoustic tonal pulse down the pipe and in less than 3 minutes makes a blockage assessment and…

Case Study: Horizontal Directional Drilling (HDD) Hydrofracture and Pipe Installation Load Analysis, Prediction VS Actual

Inadvertent drilling fluid returns is one of the most significant issues for HDD operations due to the potential effect it can have on the environment, the integrity of the borehole and the ability to remove cuttings from the borehole. These issues can seriously impact on the overall success of a pipe installation via…

Case Study: Jacking Force of Curved Pipejack (Prediction VS Actual)

Jacking force is a critical element of a pipejacking operation. It influences the length of the tunnel drive, pipe integrity, and location of the shafts and utilisation of Intermediate Jacking Stations. Thus, it has strong impact on the constructability and end use of the pipejacking operation. Therefore, it is…

Case study: Warragul Trunk Sewer

The Warragul Trunk Sewer project was part of the $A13 million Warragul works undertaken by Gippsland Water to improve sewerage systems within the region. Approximately 1,5000m of microtunnelling was utilized during the project, which connected residential properties to a central sewer system. This paper seeks to…

Challenging installation of large diameter HDPE pipe by directional drilling provides a comprehensive water management solution and an improved environmental outcome

This presentation describes the Chichester project and outlines the exceptional capability of the Australian PE pipe industry to deliver value to asset owners. After 85 years of operation, the pipe owner, Hunter Water, decided to replace the above ground 900mm metal pipe line that had been prone to flood damage and…
