December 2007

From the Chairman’s Desk

The International View Firstly, a quick overview and impressions from the Roma 07 International No-Dig Event held in Rome in September 2007. With 300 paying delegates, 186 participating exhibitors, 50 members and guests, 98 exhibitor/sponsors, 1,650 visitors and a total of 2,250 sq m of exhibition space, the first Mediterranean No-Dig was considered a successful event.

Secretary’s Corner

NEW MEMBERS On behalf of the ASTT, I extend a warm welcome to the following new members:

ASTT showcases latest techniques at NZ conference

Live demonstrations at the New Zealand Water and Waste Association conference in Rotorua on 20 September showcased the latest advancements in technologies for the rehabilitation of wastewater systems.

Trenchless Australasia 2008 - less than 3 months to go

As Trenchless-Australasia 2008 draws near, excitment continues to build with the draft program now available.

“Could do better”

James Thomson

The first No-Dig was held in London in 1985 and for the first time a disparate set of installation and rehabilitation methods were brought together under the name “Trenchless Technology”.

Global trenchless community meets in Rome

The ASTT again had a presence at the ISTT Conference, which took place in Rome. Co-hosted by the International and Italian Societies for Trenchless Technology with the rallying cry, “All Roads lead to Rome”, 348 delegates from 40 countries met at the Ergife Conference and Exhibition Centre in Rome 10 -12 September 2007 for the 25th ISTT annual No-Dig Mediterranean 2007. The ASTT stand was manned by Jeff Pace and Chris Bland, while Australian reliners had a strong presence amongst delegates with Geoff Weaver of Interflow, Chris Meredith of Kembla and Trevor Groenveld of CLM in attendance.

Nominations open for project of the year

It’s time to nominate outstanding projects for Project of the Year awards. The Awards will be presented at the Gala Dinner at Trenchless Australasia 2008, the 7th National ASTT Conference and Exhibition and the winning projects will also be featured in an upcoming issue of Trenchless Australasia.

An Australian First

In Situ Spray Lining for the Rehabilitation of Watermains – A Sydney Water and an Australian Water Industry First In its drive to become the market leader in the provision of innovative pipeline solutions to water and wastewater infrastructure owners, CLM Trenchless has recently acquired the licence for the spray lining system using the Copon Hycote 169HB (Hycote) product, developed by UK coatings company E.Wood (3M).

Bringing water to drought-ridden Qld requires novel hard rock technology

Population and commercial booms in southeastern Queensland have put substantial pressure on the region’s dwindling water supplies. The Western Corridor Recycled Water (WCRW) project will replenish the stores by piping purified recycled water to power station and industry – leaving the remainder for drinking and consumer use.

Taking on the tough HDD projects and winning

Living on the outskirts of Sydney’s northwest has some major advantages. Being surrounded by some of Australia’s most picturesque mountain ranges along with the quiet and peaceful serenity of the bush makes this area highly priced for people wanting a change of pace from the hustle and bustle of city life.

Tunnel boring on the Southern Regional Water Pipeline project

As part of the Southern Regional Water Pipeline (SRWP) project in Queensland, Microtunnelling Tunnel Boring Machines (MTBMs) are being utilised to tunnel underneath rivers, through hills and under major roadways to minimise impact on the environment and the local community.

Tenders let for Timaru sewer pipe tunnels

Tenders with a combined value of around $15 million have been let by the Timaru District Council, New Zealand, to tunnel underneath some streets on the coastal belt and link up sections of pipes as part of the council’s Main Trunk Sewer upgrading program.

Pipe Jacking enables sewer upgrade to cross major highway

Maunsell has successfully taken on the design and construction management of the replacement main trunk sewer serving the northern suburb of Johnsonville on behalf of Wellington Water Management, the local council controlled organisation acting for Wellington City Council, New Zealand.

Family and reliable equipment the cornerstones for business success

Mark Hunt’s business philosophy is simple but effective – earn more than you spend. His down-to-earth attitude to running a business saw him branch out alone at only 21 years of age, after completing an apprenticeship as a plumber.

Kembla ‘goes into bat’ and scores big

Well known for more than 14 years for its use of the latest No-Dig systems for sewer rehabilitation, Kembla Watertech Pty Ltd has recently added more runs to its Trenchless Technology scoreboard with successful water main rehabilitation projects at Bowral, New South Wales, and Milang, South Australia.

Sewer relining works at Cockatoo Island

Cockatoo Island, the largest island in Sydney Harbour, dominates a special triangular space bounded by Balmain, Drummoyne, Hunters Hill, Woolwich and Greenwich, with the other two smaller knolls of Spectacle and Snapper Islands nearby.

Premium Pipe Services starts relining contract

Premium Pipe Services, a subsidiary of integrated pipe services and supply company ShieldLiner Limited, has commenced a contract with the City of Kalgoorlie-Boulder for sewer replacement works.

Another TT Group first in Australia

Grundo Pit with Rockhammer Power Supply - Elizabeth Bay, Sydney

Grundoburst 1250 G on site in Warsaw, Poland

In the old part of Warsaw in Poland a ND 400 mm clay pipe required replacement over a length of 30 m. Inspection of the mains by the water and sewerage company in Warsaw showed regular sand on the bottom of the mains, so that it was apparent that the main was fractured and bit and pieces fell to the bottom of the pipe. This presented a permanent problem of undercarving the road surface – an imminent danger to the public.

New Interflow development seals gap in sewer renewal technology

The completion of a recent project in Geelong has demonstrated how an important advance pioneered by sewer renewal contractor Interflow Pty Ltd has extended the possibilities for sealing of lateral connections to lined sewers.

Benefits of non-disruptive asset management

Kevin Bainbridge, A.Sc.T.

Trenchless rehabilitation technologies have been in existence for several decades now. However, use of these methods has risen dramatically over the last 5 to 10 years. Although there are likely many contributing factors associated with the increased popularity of trenchless rehabilitation, the most influential factor — and the one which will sustain its popularity for some time — has been the introduction of asset management philosophies into the infrastructure industry.

Light cured GRP in structural pipeline rehabilitation

Cured in place lining is an efficient and reasonably priced method for the trenchless rehabilitation of gravity and pressure pipe systems.

Applied Felts - a leader for over three decades

Every pipeline rehabilitation project has its unique challenges. That’s why you need a company that not only understands these challenges, but helps you solve them. As the world’s largest independent manufacturer of quality felt liners, Applied Felts has been a leader in the trenchless CIPP industry for more than three decades.
