Of the £4 billion worth of damages, £186 million is attributed to vital water infrastructure. In response to the report, British water authorities have recognised that much of their vital infrastructure, including distribution assets and treatment plants situated near rivers, require increased protection. NASTT rewards young trenchless professionals The North American Society for Trenchless Technology (NASTT) has announced a new scholarship program and a new award to honour the memory of two influential people in the trenchless industry and to encourage young professionals in the trenchless industry. The Michael E Ardent Memorial scholarship program includes five individual scholarships of $US5,000 each to be awarded to eligible students who are members of a current chapter of NASTT. The Trent Ralston Award for Young Trenchless Achievement has been created by the NASTT to acknowledge a young individual who has demonstrated excellence in the early stages of their career and has made a valuable contribution to the Trenchless Technology industry. EPA invests to renew or retire aging water infrastructure The EPA will invest $US10 million in the Aging Water Infrastructure Research Program to evaluate new technologies that will assist utilities in coping with aging and failing water and wastewater systems in the United States. The research will be undertaken by the US Water Environment Research Foundation and will examine innovative tools and procedures to improve the maintenance, rehabilitation, and replacement of aging sewer lines, water mains, and other components that constitute water and wastewater infrastructure in a cost-effective manner. Hawaii commended for green wastewater projects The Hawaii State Department of Health (DoH) has been recognised for its innovation and program management in underground infrastructure and its ability to exceed the American Recovery and Reinvestment Act’s Green Project Reserve requirements. One such green project is Honolulu’s Waimalu Sewer project, which is currently undertaking microtunelling operations. The late Trent Ralston.

KG Tief- und Rohrleitungsbau Subterranean storage caverns for natural gas are being built on the Ems River, near the city of Leer, in Northern Germany. This requires flushing out salt mines to produce large underground cavities. In order to discharge the concentrated saltwater (brine), a 42-kilometer long pipeline must be laid to the Outer Ems near the city of Emden – the last 283 meters of the outflow pipe at the “Rysumer Nacken” artificial dune field will be built using the new one-pass Direct Pipe® method developed by Herrenknecht. This innovative installation technology means that any disturbance of the delicate natural environment around the East Frisian mud flat can be kept as minimal as possible. Compared with conventional methods, Direct Pipe® does not require the costly and timeconsuming installation of steel sheet piles alongside the offshore route. With the help of a Pipe Thruster, the prefabricated pipe string will be pushed directly towards the inlet structure located in the Outer Ems. The excavation work can be carried out simultaneously by a tunnelling machine which is coupled to the pipeline and, after reaching the target, can be disconnected and removed. Direct Pipe® met the high expectations of all parties involved as far as both efficiency and environmental protection are concerned and also made a valuable contribution towards securing future supplies of natural gas.
