German Society for Trenchless Technology Announces Winners of Annual GSTT Awards

At the opening event of 2015 WASSER BERLIN INTERNATIONAL and No-Dig Berlin conference in Berlin, the German Society for Trenchless Technology (GSTT) presented its annual GSTT Awards for achievement in trenchless construction projects.

WASSER BERLIN INTERNATIONAL Congress and No-Dig Berlin conference is taking place March 24-27 at the Berlin ExpoCenter City in Berlin. This is the second year in a row that the two conferences have taken place together.

The aim of the GSTT Awards is to raise public awareness for the huge technical, economic and ecological



opportunities that this innovative construction method offers, particularly in cities with confined spaces and high traffic density.

Chairman of the board of GSTT Professor Jens Hölterhoff presented the bronze award to the representatives of Vattenfall Europe Wärme AG on behalf of Arge Düker Müggelspree, which completed a district heating supply line that crosses beneath the River Spree. The silver award went to the community of Oss in the Netherlands for its rehabilitation, using liners, of a 1.5-m wide sewage canal, a construction project that it undertook for the first time. The GSTT gold award went to the Essen-based Emschergenossenschaft for its construction of a 47-km long stretch (section 30) of a new canal transporting dirty water. This represents the largest trenchless construction project in Europe. The foreign award went to the National Water Company of Saudi Arabia for its completion of a wastewater collector in Mecca.
