(openPR) - Reaching the grand old age of 100 is generally a very good reason to celebrate – but not if you´re talking about the sewage networks in the western industrialised nations. In Germany alone around 18% of the 485,000 kilometres of public network of sewage pipes are damaged. In the private sector the damaged quotient is put at 20% of a total of 1.3 million kilometres. Technology is not the problem here, because for a long time now modern methods and solutions have been available for lasting repair of any damage. In fact in recent years civil engineering work has been moving further and further away from conventional methods, particularly in pipe-laying and canal work, as well as in special areas such as well drilling, drinking water supplies and geothermics. Modern machinery in combination with electronic communication and monitoring techniques is now greatly facilitating working operations. The 28th bauma, which takes place from 23 to 29 April 2007 in Munich, will be offering a full overview of the current market in this field.
Modern drilling techniques are essential for a number of civil engineering operations. In geothermal drilling operations, for example, equipment mounted on tracked vehicles or moving gear can now reach depths of 350 to 400 meters.
