Graduation thesis introduces the theoretical principles for construction of water supply and urban drainage systems, which are then applied on settlement Stočje in Kropa, Carniola region. In the first part the general characteristics and construction of the simultaneous and separate sewer system, together with the main elements of the water supply system and legislation in this field are presented.
In the second part, the construction of both systems is described in detail for the settlement Stočje in Kropa. In this part of the settlement I have proposed two alternative pipe lines and analysed which option is better, according to the way of construction (simultaneous or separate). The system is comprised of one primary pipe and five secondary pipes. An inventory of construction work was made, together with the assessment of costs for simultaneous and separate construction. The calculations were based on the profiles for different pipe sections, based on gravitational water drainage system principles and surveying data. Simultaneous construction proved to be cheaper, when compared to separate one. Moreover, this way of construction brings additional benefits, such as construction can take place only once at one location, possibility of one contractor, faster construction and reconstruction of the whole road, not only a part of it.
Drinking water has to be safe and impeccable, as it has influence on our health. If the sanitary water is inadequate, it can cause different diseases that is why the water distribution and sewerage systems need to be of a sufficient quality. With the simultaneous construction, we can provide appropriate systems and reduce the costs of the investment.
