The need to identify leakages in the water pipeline infrastructure is vital in the field of water cycle monitoring. Leakages in water pipes could imply a large loss of drinking water and is also a possible threat to our health; when water pressure in the damaged pipes drops, surrounding water is allowed to enter the pipes. Managing these leakages is therefore a high priority, especially since rehabilitation of damaged pipe systems can cut the costs with 30 to 70 % compared to replacing them. However, rehabilitation must start with identifying the problem, which in this particular case means finding leakages and cracks in the water pipes. As the traditional damage-reducing techniques and equipment for obtaining information of underground media has proven to be insufficient, a new technology for inspection and evaluation of water pipe conditions has been the aim for the project WATERPIPE.
