Preliminary Solution for Rehabilitation and Expansion of the Čepić Settlement Water Supply System Using the WaterCAD V8i Computer Program

Ovim diplomskim radom izvršen je idejni projekt vodoopskrbnog sustava naselja Čepić koje se nalazi na istoku Istre, u sastavu općine Kršan. Unutar rada analizirane su dvije varijante vodoopskrbnog sustava. Na početku rada definirane su osnovne značajke promatranog područja, definirane su mjerodavne količine vode za pojedine kategorije potrošača. Nakon toga, izvršeni su hidraulički proračuni pomoću Microsoft Excel programskog paketa. Proveden je hidraulički proračun volumena vodospreme. Za valorizaciju rezultata hidrauličke analize korišteni su računalni programi WaterCAD V8i i Urbano Hydra. Vodoopskrbna mreža postavljena je ispod prometnica, a kao materijal cijevi odabrano je lijevano željezo. Unutar WaterCAD V8i računalnog programa analizirana je upotreba čeličnih i PVC cijevi. Također, analizirana je pojava požara unutar vodoopskrbnog sustava i njezin utjecaj na fizikalne veličine. Rezultati hidrauličke analize unutar WaterCAD V8i računalnog programa prikazani su pomoću “Color coding” opcije koja omogućava jasan prikaz promjene fizikalnih veličina pomoću boja. Unutar Urbano Hydra računalnog programa, osim hidrauličkog proračuna, izrađeni su uzdužni i poprečni profili za pojedine dionice vodoopskrbnog sustava.Within this master’s thesis, water supply system of the Čepić Village, which is located in the east of Istria, in the municipality of Kršan, was designed. Two variants of the water supply system were analyzed in this work. At the beginning of the thesis, the basic features of the observed area were defined, then the relevant quantities of water for certain categories of consumers were defined. After that, hydraulic analysis were performed using the Microsoft Excel program package. The calculation of the water reservoir volume was carried out. The computer programs WaterCAD V8i and Urbano Hydra were used to valorize the results of the hydraulic analysis. The water supply network was placed under the roads, and cast iron was chosen as the pipe material. The use of steel and PVC pipes was analyzed within the WaterCAD V8i computer program. Also, the occurrence of fire within the water supply system and its impact on physical quantities was analyzed. The results of the hydraulic analysis within the WaterCAD V8i computer program are displayed using the "Color coding" option, which enables a clear display of physical parameters using colors. Within the Urbano Hydra computer program, in addition to the hydraulic calculation, longitudinal pipeline and cross sections were created
