Environmental aspects of water supply to the Kyrgyz-Turkish “Manas” University campus and their assessment in the condition of the “Greenmetric” system criteria
Abstract
The paper considers the environmental aspects of water supply in the campus of Kyrgyz-Turkish “Manas” University, and evaluates them in the context of the indicators of the “UI GreenMetric World University Ranking – 2024” system: SI-infrastructure (70.33%); EC-energy and climate (37.62%); WR-water (70%); WS-waste (66.67%); TR-transport (77.78%); ED-education and research projects (66.67%). It was noted that within the campus, there is a centralized city water supply system, and in addition, four wells have been drilled, fed from the groundwater of the Chui Valley. The main consumers of water are educational, industrial, household and agricultural campus facilities. Part of the water from the springs is used for drinking purposes. Taking these circumstances into account, the chemical composition of the model water was established. Thermodynamic modeling of an aqueous solution was carried out at a minimum Gibbs energy and the concentration distribution of elements, cations and anions in the liquid phase was established. It has been shown that the pH value of water ranges from 7.3 to 7.62, and the redox potential is positive. Accordingly, the properties of water are restorative in nature and are quite suitable for drinking purposes, which means solving an important practical problem.
