The 8th National ASTT Conference and Exhibition held at Melbourne Park, Melbourne from 20–22 September 2009 was a fantastic event and a great showcase for the trenchless industry.
The biggest ASTT national conference ever – Trenchless Australasia 2009 – provided a world-class forum for the trenchless industry to learn about the latest developments, see equipment on show and meet new people. Managing Editor Kate Pemberton reports.
New members On behalf of the ASTT, I extend a warm welcome to the following new members.
Australian mining supplies organisation, ADG Global Supply, recently signed an exclusive agreement with Robbins HDD LLC, enabling the distribution of Universal horizontal directional drilling (HDD) rigs and related trenchless drilling equipment in Australasia. Trenchless Australasia spoke with Paul Johnson from ADG Global Supply about this exciting partnership.
The keynote addresses at the 8th National ASTT Conference and Exhibition were from ISTT Chairman Dr Dec Downey, ISTT Vice Chair Dr Samuel Ariaratnam, Director of the Water Reclamation Department PUB Singapore Tan Thai Pin, Executive Director of the Institute of Public Affairs John Roskam, and Executive Director of the Water Services Association of Australia Ross Young.
ASTT Trenchless Person of the Year Alan Sutton has spent three decades in the industry, working at the forefront of developments in relining technology. Kate Pemberton spoke with Alan about the history, product development and future of relining in Australasia.
Trenchless Live 2010 will be an experience like no other – a chance to see, hear and touch Trenchless Technology in action.
The underground became the ‘above ground’ in Rotorua, New Zealand, for a No-Dig live demonstration organised by the ASTT at the annual New Zealand Water & Wastes Association conference.
Covering an area of 3,425 square kilometres, Dubbo City Council is active in inspecting, rehabilitating and extending its underground infrastructure. Trenchless Australasia spoke with Infrastructure Engineer Water and Sewerage Roger Reynolds about the benefits of using Trenchless Technology in order to leave the city undisturbed.
According to Executive Director of the Institute of Public Affairs (IPA) John Roskam, the trenchless industry must communicate to the government the essential role of Trenchless Technology in maintaining and building underground infrastructure, linking the industry with productivity, population and participation.
The Australian Green Infrastructure Council (AGIC) will provide a robust framework to assess and rate sustainability performance for infrastructure projects.
A principal objective of the ASTT is to promote the science and practice of Trenchless Technology. To achieve this goal the ASTT has commissioned a set of industry specific guidelines, standards and specifications in three of the most commonly applied trenchless methods, HDD, pipe bursting, and microtunnelling and pipe jacking.Mandy Wong
Severe flooding during Tropical Cyclone Charlotte in February 2009 saw the Far North Queensland township of Karumba left without a potable water supply after part of the 44 kilometre Karumba Water Supply Pipeline was washed away. Carpentaria Shire Council contracted JR & LM Tracksons Directional Drilling to complete urgent repairs to the pipeline under the Norman River, using Vermeer's D330 x 500 HDD rig, in just seven weeks.
Hunter Water Corporation awarded a contract to UEA in early 2009 to design and construct approximately 510 metres of gravity sewer mains using horizontal directional drilling to install the pipe. The pipeline was installed at a maximum depth of 26 metres below the crest of the hills located in the Glenrock State Recreation Area in Kahibah, 7 kilometres southwest of Newcastle in New South Wales.
Water Infrastructure Group has been awarded contracts from Sydney Water to undertake $A9 million rehabilitation projects for the Bondi Ocean Outfall Sewer and the Northern Suburbs Ocean Outfall Sewer Gore Creek and Burns Bay aqueducts.
A relining project at Fox Studios in Sydney has taken centre stage. Fox Studios is built on the original heritage site of the Royal Agricultural Society’s Sydney Showground, home to The Sydney Royal Easter Show for more than 100 years.
Steve Apeldoorn from ProjectMax believes that the trenchless industry in New Zealand is poised for considerable expansion, however the development of standards and guidelines for the industry is an important component of ongoing success and growth.
InfraTrain New Zealand has launched an extensively revised qualification for horizontal directional drilling (HDD), which has been developed in partnership with the trenchless industry.
The Northern Sewerage Project will increase the capacity of the sewerage system for Melbourne’s northern suburbs. The NSP Project Director Rob Muley spoke to Trenchless Australasia, providing a project update and status report on the three tunnel boring machines – Gemma, Victoria and Julia – named by a local primary school.Norman Joyal, Associate, Jacobs Associates
The trenchless industry is technologically advanced and consistently innovative. Cutter soil mixing technology is one such example that has been developed to construct shafts for microtunnelling projects. Norman Joyal told delegates at Trenchless Australasia 2009 about one of the first projects in the United States using this technology to build microtunnelling shafts.Kaleel Rahaim, Interplastic Corporation
Eric Wood developed a process that changed the world of infrastructure renovation: a process that has changed in its thirty odd years of use; and it will continue to evolve.
Insituform’s cured-in-place pipe (CIPP) lining systems are continuing to develop an excellent reputation in the rehabilitation of severely deteriorated stormwater pipes.Paul Hebberd, TerraMacs Limited
While times have been challenging, the trenchless industry in New Zealand and Australia is set to prosper, with the governments in both countries committed to large scale broadband upgrade projects over the coming decade.
The ASTT is advocating on behalf of industry to educate Government and public policy makers about the benefits of using Trenchless Technology, such as HDD, for the installation of Australia’s proposed National Broadband Network.Lyndsie Mewett
Pigs are integral for the maintenance of pipeline infrastructure. Broadly, there are two different types of pigs – cleaning pigs and intelligent pigs (or in-line inspection tools). Here, Trenchless Australasia, looks at the basics of cleaning pigs. This article looks at cleaning pigs for the petrochemicals industry, and provides a water pipeline case study opposite.
Sewer Equipment Company (Australia) – SECA – is expanding its business and services in CCTV and pipe maintenance – and is relocating before Christmas.
Regular high pressure jetting of sewer mains is an essential and accepted part of routine pipe maintenance. The process clears pipelines of roots, debris, obstructions and cleans the inside of the pipe. As a result, the hydraulic capacity of the pipe is typically restored and the potential for surcharges and overflows is reduced.
Water is becoming increasingly scarce and projects require tighter economic controls, companies in the drilling game need affordable ways to process their mud solids. National 'down the hole' distribution company DTH Products has partnered with Tibban, makers of the MudPuppy line of solids control units, and industry leader Baroid to bring together an end-to-end solution that saves drillers time and money.Nicholas M Zembillas, Senior Vice President/Principal, Cardno TBE
A lack of reliable information for the location of underground utilities can result in costly conflicts, damages, delays, utility service disruptions, redesigns, claims injuries and even lost lives during construction activities. While the location of subsurface utilities might be found on plans and records, experience has often shown that the utility locations are not exactly as recorded or the records do not fully account for the buried utility systems.Kurt Jaks, Flexible Pipe Cleaning Tools
Recyclers commenced operations in the late 1970s. Since then water restrictions and the need to conserve this valuable resource has caused the industry to take a closer look at water recycling drain cleaners.
