We live in an era where human activities strongly influence every aspect of nature. Water is a part of nature and, as we know, a necessity for human survival. River flows have significantly changed in the last 10 years, with pronounced periods of drought and floods. In various parts of the world, such as Africa and Asia, interstate conflicts have arisen due to water resources. Water has a national significance for every country. The main goal of this master's thesis is the protection of the Una River and the improvement of water quality.
This master's thesis deals with the development of a conceptual solution for the drainage of wastewater and rainwater from the settlement of Klisa, located in Bosnia and Herzegovina. The Klisa settlement itself is situated within the strictly protected area of the Una National Park. Additionally, the Una River flows next to the Klisa settlement, which, according to the law on the protection of the national park, holds the status of protected water.
Within the master's thesis, two possible solutions to the wastewater drainage problem are developed. The issues are first theoretically explained, followed by the specifications of the problem, and finally, a technical-economic analysis is carried out. Various software tools such as CIVIL 3D, QGIS, EXCEL, etc., were used in the process. This demonstrates that with the construction of the sewage system, this project will contribute to the protection of the Una River water in this area.
