This article analyses the relation between the failures that occurred in the water supply network and the road traffic in the city of Cluj-Napoca in Romania. The calculations in this case study were made using the Autodesk Robot Structural Analysis Professional 2011 software. In the case study, the following types of pipes were analysed: steel, gray cast iron, ductile cast iron and high density polyethylene (HDPE). While in most studies only a few sections of pipelines, several types of pipelines and certain mounting depths have been analysed, the case study presented analyses the entire water supply system of a city with a population of 324,576 inhabitants, whose water supply system has a length of 479 km. The results of the research are useful in the design phase of water distribution networks, so depending on the type of pipe material, the minimum depth of installation can be indicated, so as to avoid the failure of the pipes due to road traffic. From this perspective, similar studies could also be carried out regarding the negative influence of road traffic on sewerage networks, gas networks and heating networks.

[Numberless Heading] Abstract[Normal] Manuscript preparation for CETRA 2014 proceedings is a fairly simplified process. Everything you need for a properly formatted article is contained in this template document which uses a feature of Microsoft Word called Styles. A style is a set of formatting characteristics that you can apply to text in your document to quickly change its appearance. When you apply a style, you apply a whole group of formats in one simple step. For example, you may want to format the sections headers to make them stand out. Instead of changing the headings one by one, you can give them a style and change them all at once. All the styles in this document are preformatted so you only need to pick an appropriate one for the part you are working on. In this example document each section that uses a specific style starts with a style name surrounded by square brackets for easy identification. The text you are reading at the moment is formatted using [Normal] style, whilst the heading above it uses [Numberless Heading] style and so on. These words serve only as a reference and should be omitted in the paper you submit. Figure 2. This group may be expanded to a list by clicking on the icon in its lower-right corner which will open a window similar to the one in Figure 3.
