Trenchless International

January 2011

From the Chairman’s Desk

I am honoured to serve you as the newly-appointed Chairman of the ISTT and look forward to doing my part to help continue the global growth of Trenchless Technology. I feel that my three years as Vice Chairman, as an understudy to Dr Dec Downey, have prepared me for the challenges and opportunities that lie ahead.

Executive Director’s Report

We begin a new year with new leadership. Dr Samuel Ariaratnam takes over as Chairman and Derek Choi is the new Vice Chairman, replacing Dr Ariaratnam. We have four new members of the Executive Subcommittee – Enrico Bio (IATT), Jeff Pace (ASTT), Sergio Palazzo (ABRATT), and Takehiro “Robert” Toyoda (JSTT). We lose two very effective subcommittee members Karel Franczyk and Olga Martynyuk – but I am happy to report that both Karel and Olga have volunteered to remain active in support of ISTT educational efforts.

Sliplining kicks goals in South Africa

Selected as the 2010 FIFA World Cup Host City Green Goal Project, the City of Cape Town’s Green Point Irrigation Project used Trenchless Technology for 80 per cent of the installation of a new 5.1 km pipeline.

Trenchless: a capital idea

n March 2011, NASTT No-Dig will be held in Washington D.C. To mark the occasion, Trenchless International takes a look Under Washington and speaks to the new ISTT Chairman, from Arizona, Dr Samuel Ariaratnam.

Under Washington, D.C. – an infrastructure forgotten

by Ralph Carpenter, Marketing Specialist/Project Manager AMERICAN Ductile Iron Pipe, AMERICAN SpiralWeld Pipe

The establishment of Washington D.C., capital city of the US, would not have been possible without the development of an intricate water and wastewater system. Here, Ralph Carpenter traces this development from a simple pine log water pipe in 1808 to today’s innovative trenchless solutions.

Taking the ISTT to the next level

Long-serving ISTT representative Dr Samuel Ariaratnam has been elected ISTT Chairman. Here, Trenchless International talks to Dr Ariaratnam about the industry, his inspirations and his plan for the ISTT.

NASTT: Chairman’s farewell message

by Chris Brahler, NASTT Chairman

My term as NASTT Chairman has come to a close. I would like to take this opportunity to thank each one of you for allowing me to serve as your Chairman for the past two years. It has been my honour and pleasure to serve NASTT and to work alongside some of the finest volunteers in the Trenchless Technology industry.

A tandem cleanout

Fort Saskatchewan, located northeast of Edmonton, Alberta, has successfully used the tandem products of LMK’s performance service lateral T-Liners and VAC-A-TEE (external cleanouts) to thwart the infiltration of roots into the sanitary and storm sewer systems.

Drilling to the ‘Top of Europe’

TERRA AG’s underground piercing tool was recently used to complete a rail crossing in the Swiss Alps, Switzerland.

World record HDD installation in New Jersey

A complex installation to replace a critical pipeline for the Middlesex Water Company (MWC) was accomplished through a partnership between CDM, an international consulting and engineering firm, Northeast Remsco Construction (Remsco) and the Mears Group (Mears).

The Dutch implement HDD for ‘gas roundabout’ concept

by John Tiratsoo, Pipelines International Editor-in-Chief

The Netherlands’ state-owned infrastructure company N.V. Nederlandse Gasunie is currently working on the Dutch government’s ambitious ‘gas roundabout’ concept utilising directional drilling for a majority of the construction’s crossings.

Crossing the Mississippi with HDD

A major new gas pipeline being constructed in the US Midwest will help supply the country’s long-term energy needs, and contribute to its ongoing energy independence and stability.

Australian project makes its mark on the world stage

by Ian Bateman, Interflow

Interflow, and project partner Sekisui Rib Loc, have been awarded the ISTT International No-Dig Project of the Year 2010 for the Rehabilitation of the North Georges River Submain, the first time an Australian pipeline renewal contractor has won this prestigious international award.

Greening the globe with trenchless

by Anne Rees

Trenchless offers a sustainable option for a wide range of underground infrastructure projects. From the construction of interstate oil and gas pipelines, to sewer rehabilitation in high density urban areas, trenchless techniques can offer tangible environmental benefits. Here, we overview the ‘green’ potential of No-Dig, and survey several environmentally friendly trenchless projects around the world.

Reducing carbon-loading

Uhrig has designed a liner to minimise energy loss by recovering the waste heat for reuse in buildings-yet another way Trenchless Technology can help reduce carbon footprints around the globe.

Marine wastewater outfalls installed by Trenchless Technology – Part One

by James Thomson

Marine Waste Water Outfalls and Treatment Systems is a book written by six authors, all with extensive experience and expertise in some aspect of the design and construction of marine outfalls. The lead author was Professor Phil Roberts of Georgia Institute of Technology, a world expert in the mixing and fluid dynamics of natural water bodies, which is fundamental to effective outfall design. It is emphasised that the book is based on pre-treatment and not the discharge of raw sewage into the oceans.

Cleaning up Thames and the River Lee

Construction has commenced on the Lee Tunnel, a new four-mile sewer which will prevent 16 million tonnes of sewage overflowing into the River Lee, located in the UK, each year.

Breaking ground around the globe

In the past year, tunnelling projects have broken ground and finished up around the world. From high profile water transfer lines through the Andes to new metro tunnels just metres below city streets, tunnel boring machine (TBM) tunnelling is more challenging, and more innovative, than ever.

International No-Dig comes to Sydney in 2013

At the 2010 International No-Dig conference, held in Singapore from 8–10 November, the ASTT successfully won the bid to hold the 2013 ISTT International No-Dig in Sydney, Australia.
