The aim of this research is to develop a conceptual solution for the water supply of the Tuliševica settlement in the municipality of Lovran. The settlement contains a small number of inhabitants and is located in a mountainous area above Lovran on relatively steep terrain. Therefore, there was no water supply network in the area until 2017. This paper presents possible solutions to the mentioned problem with the help of a branched network of gravitational flow, which starts from a reservoir built at a height of 471 meters above sea level (m ASL). The reservoir also supplies other surrounding settlements; hence it is placed at such a high position in relation to the settlement of Tuliševica, which is on average at 350 m above sea level. Large height differences result in unacceptably high pressures in the pipeline, which need to be reduced to an acceptable size. In search of the simplest and most economical solution, variants of changing the pipe profile, building a break-chamber, and installing reducing valves on the network to reduce pressures were tested.
