Trenchless International

July 2012

Executive Director’s report

John Hemphill ISTT Executive Director

If you just read the headlines, 2012 might be considered a difficult year, what with the weakness of the economy world-wide, political tensions in many regions of the world, and even a prophesy of the world coming to an end according to an ancient Mayan calendar. However, when it comes to the trenchless community, 2012 is shaping-up to be a pretty good year.

From the Chairman’s Desk

This past quarter was filled with a number of activities involving the ISTT and several affiliated societies. In total, there were six trenchless events – beginning with No-Dig Poland 2012 in April, and ending with No-Dig Moscow 2012 in June. It is nice to see so much activity in various countries.

SASTT visits Zandfontein Depot of Joburg Water

As part of the South African Society for Trenchless Technology’s 20th anniversary celebrations, the Society attended its first site visit in many years. On 28 February 2012, the Zandfontein Depot of Johannesburg Water parking lot was crowded with excited society members shaking the hands of industry friends they had not seen for over a year.

ISTT outreach gathers momentum

The ISTT’s outreach program is continually drawing more international associations together for the exchange of international knowledge with Argentina working with the ISTT to establish an Affiliated Society.

Trenchless experts head to Zhengzhou

The Chinese Society for Trenchless Technology 2012 International Trenchless Technology Conference and Exhibition was held in China’s Zhengzhou International Convention and Exhibition Centre, from 20–22 April, with great success, bringing over 300 industry representatives from across the globe to the conference and approximately 1,200 visitors to the exhibition.

Finnish Society thinks laterally at IFAT

Tough PE pipe materials ideal for installation

Andrew Wedgner and David Walton, Borouge

Polyethylene pipes have long been used to renovate ageing pipeline networks to reduce gas and water leakage levels and to install new systems. In combination with trenchless installation methods, a new pipeline can be installed at a low cost without disturbing city flow or damaging the environment. Here Borouge details three innovative case studies.

Inaugural India No-Dig brings industry together

Fifth Jubilee proves popular in Poland

Poland’s fifth Trenchless Technology International Jubilee Conference and No-Dig Poland 2012 exhibition, held in Kielce from 17–19 April 2012, was a great success.

An underground success

The 2012 Underground Infrastructure Research International Conference and Exhibition, held from 5–6 June in Niagara Falls, Ontario Canada was a resounding success with record numbers in attendance.

An eventful year in France

France sans Tranchée Technologies has a series of exciting trenchless events taking place across France in 2012.

Celebrating trenchless in Colombia

The in and outs of pipe jacking

Andrew Marshall, Pipe Jacking Association, UK

Pipe jacking is a specialist tunnelling method for installing underground pipelines with minimum surface disruption. Primarily used for new sewer construction, it is also used for sewer replacement and relining, gas and water mains, oil pipelines, electricity and telecommunication installations, culverts and subways.

Microtunnelling mapped for Marmara Sea

ISKI, Istanbul’s Metropolitan Water and Sewerage Municipality, has commenced three new microtunnelling projects that will provide Turkey’s inland Marmara Sea with better environmental protection.

Tunnelling success Down Under

The Melbourne Main Sewer Replacement, an Australian project upgrading the historic century-old main sewer in Melbourne, has progressed well over the past 12 months and was commissioned in May 2012, tracking on schedule for completion in mid-2012.

The short and tall of pipe rehabilitation

The water and sewage infrastructure renovation market is particularly challenged by pipes with extremely large or extremely small diameters – spiral-wound pipe lining provides one of the most minimally invasive techniques for these difficult pipe ranges.

A burst of inspiration in Germany

Here Trenchless International looks at two pipe bursting case studies where STG Braunsberg uses Tracto-Technik equipment for fast installation to fight rising flood waters and to renovate pipe under a busy road.
