Conceptual solution of the water supply system of Brezovica pri Borovnici, Niževec, Zabočevo, Dražica in Ohonica

Magistrsko delo obravnava idejno zasnovo vodovodnega omrežja za naselja Brezovica pri Borovnici, Niževec, Zabočevo, Dražica in Ohonica. Za potrebe naloge je bil urejen horizontalni in vertikalni potek trase vodovodnega omrežja s pomočjo programske opreme Sewer+ ter obdelani in pripravljeni vhodni podatki za zagon hidravličnega modela s programom Epanet. Hidravlični model je bil ustrezno uravnan z vidika vzdrževanja, optimalnega delovanja in ekonomičnosti, pri čemer so bili upoštevani vsi veljavni predpisi. Zasnova se deli na dva dela, pri čemer so bile v teoretičnem delu prikazane osnovne enačbe za dimenzioniranje elementov vodovodnega sistema, v praktičnem delu pa je bila predstavljena problematika, ki ji sledi še analiza rezultatov hidravličnega modela in opisana izvedba vodovodnega omrežja z vsemi potrebnimi elementi, ki so podprti z grafičnimi prilogami. Dimenzioniran je bil vodohran, črpališče z vodnjaško črpalko, tlačni cevovod za napajanje vodohrana z upoštevanjem vodnega udara, gravitacijski razdelilni cevovod z umeščenimi jaški za redukcijo tlaka in hidrofor za dvig tlaka v omrežju za manjši odsek. Za konec je bila narejena stroškovna analiza, ki je podala grobo oceno investicije.This master’s dissertation discusses a conceptual solution for the water supply system in the villages of Brezovica pri Borovnici, Niževec, Zabočevo, Dražica, and Ohonica. For the purpose of this thesis, the horizontal and vertical course of water supply alignment were edited in Sewer+ software. Additionally, for the activation of the hydraulic model, entry data were processed and prepared with Epanet software. Hydraulic model was suitably adjusted in the aspect of maintenance, optimal activity, and economical efficiency, at which all valid regulations were taken into consideration. The outline of master’s dissertation consists of a theoretical and practical part. First, the elementary equations for designs of elements for the water supply system are introduced. In the second, practical part, the discussion of the thesis is presented, followed by the analysis of hydraulic model results and description of a corresponding water supply system, supported with graphical appendices. In addition, the analysis is supported with the designs of water reservoir, a pumping station with the well water supply, pressure pipeline system for the water supply of water reservoir, including the water hammer, pipeline gravitational manifolds with placed-in manhole for pressure reduction, and a hydrophore for pressure raise in the system of a smaller section. In conclusion, a rough approximation of investment is presented with the analysis of cost calculations
