Introduction: The Sustainable Development Agenda was adopted with the purpose of achieving the goals that were set in 2000 with the adoption of the "Millennium Declaration". In the Agenda, it is stated among the other things to ensure by 2030 that all girls and boys complete free primary and secondary education and also achieve universal and equitable access to safe drinking water and sanitation for all. Purpose: The purpose of the master's thesis consists of a hygienic-technical analysis of a selected house and a local school with an emphasis on drinking water supply and the analysis of personal hygiene knowledge among students of the fourth grade. Methods: In the master's thesis, we used the descriptive method of work. A hygienic-technical analysis of the local house and school was carried out with the help of a systematic observation list and technical measures based on the state of the situation were proposed. In the local school, we analyzed the knowledge of the students in the field of personal hygiene by using a deliberately prepared test adapted to the target population. After the analysis of the tests, we carried out five-day training in the field of personal hygiene. Results: After the hygienic-technical analysis of the house and school, we found out that certain deviations represent a health risk for residents and students in the school. The health risks in the local house are poor sanitation, unprotected drinking water well, and poor hygienic-technical conditions in the kitchen. Preparation of school meals in the yard and the lack of wash basin and soap represent a health risk for the students in the school. The results of the first test in the field of personal hygiene showed that students connected hygiene with religion, learning, washing clothes, and cooking. After the educational measures, students started to differentiate elements of personal hygiene from other types of hygiene and religion. Discussion and conclusion: Based on sustainable development goals, we proposed technical measures to eliminate hygiene-technical deviation, which could achieve the sustainable development goals that are written in The Sustainable Development Agenda.
