Employees of construction and public works companies carrying out work to install drinking water pipes must take training abroad to obtain the skills to carry out this work and to meet the conditions required by the municipalities. As a result, companies do not have the opportunity to properly train their employees, which has an impact on the quality of the work and the necessary execution times, and on the other hand it can potentially generate poor quality work that can have an impact on the quality of drinking water distributed across the country. This may result in the distribution of water of poor non-potable quality.In addition, the training provided in the others does not take into account all the specificities of the work to be carried out in Luxembourg (types of products, methods of assembly of pipes, controls, etc.).The project consists of structuring and developing a training programme qualifying on the topic of the installation of drinking water pipes.
