To optimize natural resources, CAU has introduced rainwater harvesting systems that capture runoff from rooftops, parking areas, and green spaces. This water is directed into storage tanks and two recharge pits, where it is absorbed back into the ground to replenish local groundwater reserves. Harvested rainwater is also used for irrigation and landscaping, reducing the demand for potable water in non-drinking applications.
Water-Efficient Infrastructure
To minimize daily consumption, CAU has systematically upgraded its facilities with water- efficient appliances.
- In dormitories, 196 combined toilet and bathroom units are equipped with dual-flush systems and low-flow showers.
- Two shared laundry facilities feature 14 high-efficiency washing machines, reducing water use per cycle.
- On the main campus, 36 bathroom facilities for men and women are fitted with sensor- based or push-tap washbasins and low-flush toilets.
This integrated system has led to an average efficiency rate of 77% across all appliances, with continuous monitoring and upgrades performed by the Facilities Management Department.
Looking forward, CAU has committed to expanding its water conservation efforts through the construction of artificial eco-lakes and the development of new green zones on campus. These lakes will serve a dual purpose:
As reservoirs, they will collect and store rainwater for non-potable use.
As biodiversity hubs, they will support local ecosystems, create natural cooling effects, and provide hands-on learning opportunities for students and researchers.
The eco-lake project has already entered its initial construction phase, underlining CAU’s strong commitment to long-term climate resilience and innovation.
Access to Clean and Safe Water on Campus
Ensuring the availability of clean and safe drinking water is one of the priorities of our university. Recognizing that access to water directly impacts the health, comfort, and overall well-being of students, faculty, and staff, the university has implemented a system that guarantees reliable water provision throughout the campus.
Filtered and boiled water is made available on every floor of university buildings, providing reassurance that the water consumed by the community meets hygienic and health standards. To complement this, water coolers are installed on each floor, allowing individuals to conveniently access both hot and cold water at any time of the day. This infrastructure is especially important in supporting a diverse university environment, where students and staff spend long hours on campus engaged in academic and extracurricular activities.
The presence of safe water sources within close reach reduces the need for students to purchase bottled water, thereby lowering costs for individuals and minimizing plastic waste generation. It also encourages healthy hydration habits by ensuring that water is always accessible in study areas, administrative spaces, and common facilities.
Through these efforts, the university not only addresses the essential need for safe water but also strengthens its commitment to creating a supportive and sustainable campus environment where the well-being of the community is placed at the center of development.
Clean Water and Sanitation - SDG 6
Central Asian University considers sustainable water management a key pillar of its Climate Action Plan 2030 and commitment to the United Nations Sustainable Development Goals. In response to growing water scarcity challenges in Uzbekistan, CAU focuses on infrastructure resilience, technological efficiency, and community education to ensure responsible water use across its campus.
The university has established a water reserve system that provides two full days of supply during municipal shortages, along with emergency barrels for fire safety. Rainwater harvesting systems collect runoff from rooftops and green areas, storing it for irrigation and recharging groundwater reserves. Campus facilities feature water-efficient appliances, including dual-flush toilets, low-flow showers, and high-efficiency washing machines, achieving a 77% overall efficiency rate.
Water conservation is also embedded in education and campus life. Students and staff participate in awareness campaigns and sustainability workshops, while water-saving practices are integrated into academic research and innovation projects.
Looking ahead, CAU is developing artificial eco-lakes and new green zones that will serve both as rainwater reservoirs and biodiversity hubs, enhancing climate resilience and providing real-world learning opportunities. In addition, filtered and boiled drinking water is available on every floor of campus buildings, supported by water coolers that promote convenient, healthy hydration while reducing plastic waste. Through these integrated actions, Central Asian University demonstrates that sustainable water management is achievable and scalable in higher education, reinforcing its role as a regional leader in environmental responsibility and community well-being.
