Trenchless International

April 2012

From the Chairman’s Desk

This past quarter was quite eventful for the ISTT. I am pleased to announce the formation of three new Affiliated Societies. Our first ever Society located in the Middle East was marked by the United Arab Emirates Society for Trenchless Technology (UAESTT), which includes Abu Dhabi, Ajman, Dubai, Fujairah, Ras al-Khaimah, Sharjah, and Umm al-Quwain.

Executive Director’s Report

ISTT Chairman Samuel Ariaratnam and I attended the North American Society for Trenchless Technology (NASTT) No-Dig Show in March in Nashville, Tennessee, US. Also attending were Klaus Beyer from the German Society for Trenchless Technology (GSTT), Andrzej Kuliczkowski from the Polish Society for Trenchless Technology (PSTT) and Helio Rosas and Diogo Dantas from the Brazilian Society (ABRATT). I had the opportunity to address conference attendees on the role of key participants in the trenchless movement, and in particular, the pivotal place held by trenchless societies.

Napa uninterrupted

The installation of a 7,400 ft section of watermain was an impressive feat for the City of Napa located in California. Here Project Engineer Megan Thomas talks with Trenchless International about the challenges of drilling under the Napa Valley Memorial Park Cemetery, Napa City College, Kennedy Park Golf Course, and Native-American artefact sites.

Surveying São Paulo’s sewage network

Midway through the third and final phase of São Paulo’s Project Tietê, designed to improve the city’s sewage network for a rapidly expanding population, Trenchless International takes a look at the tunnel boring work going on underneath the city.

No-Dig: a significant key to the buried infrastructure deficit

By Kevin Bainbridge, Robinson Consultants

The infrastructure deficit across North America is one of the most significant issues facing society today. Buried water and wastewater infrastructure is a large part of this deficit and the failure of this infrastructure will have a profound effect on society’s quality of life.

Hammering through tough jobs in Germany

In order to connect 400 residential houses to the German Telecom glass-fibre network, Trench-Project turned to a trenchless installation using Tracto-Technik’s displacement hammer.

The right tool for the job

By Randy Happel, Two Rivers Marketing, Des Moines, Iowa

The role that tooling selection plays in enhancing productivity is important to ensure a successful project. Here, Randy Happel helps break down the process in selecting the right tool for the job and how to extend the life of machines.

Cleaner shafts with compressed air

Hermes Technologie has expanded its repertoire of coating abilities, adding accident prevention technology and automated shaft coating to complete complex jobs.

Renovating to preserve history

The historic Balans Sewer in Middleburg, the Netherlands, was in extremely poor condition, allowing wastewater to seep into the ground below. Contractor Van der Velden Rioleringsbeheer explains how a cured-in-place liner restored and preserved the culturally important sewer.

Drilling in the Ukraine

The impact of Trenchless Technology is far reaching and improving infrastructure all over the world. Eastern Europe is an example of this progress, which can be illustrated by looking at Trans-VISMOS, an experienced horizontal directional drilling company located in Kiev, Ukraine.

Making history: the OPAL pipeline

The creation of the OPAL pipeline has not only utilised trenchless methods for crossing rivers, waterways and harbours in order to make history as the biggest natural gas pipeline in Europe, but has also unearthed precious historical artefact in the process.

Drilling to Treasure Island

The Treasure Island Project in Russia used HDD to install an oil transport pipeline under the Kama River and, like the Robert Stevenson story of the same title, involved an island, oil – the modern world’s treasure, and daring adventures had by the drilling crew.

Under London – this time with a lot less trenching

By Dec Downey, Principal Trenchless Opportunities Ltd

In the feature article Under London published in this magazine in July 2010 we learned of the New River constructed in 1613 by Sir Hugh Myddleton to supplement traditional water sources; the Thames and Fleet Rivers, the Walbrook and the Tyburn Stream feeding Conduits and Fountains in the City.

UK Utilities

As part of the Trenchless International’s water utilities around the globe series, this edition takes a look at the UK’s twelve water and wastewater utilities, which are a combination of publicly owned and privately owned enterprises.
