1. Reusing stored water is an effective way to conserve water resources and enhance sustainability. Here are strategies and considerations for effectively reusing stored water on our campus:
  1. Greywater from sinks, showers, laundry and rainwater are stored in our campus and treated by local company called “O‘zsuvta’minot AJ”  for reuse.
  2. That stored water is used for irrigation, water flushing and cleaning purposes such as washing sidewalks and vehicles.
  3. Storage Tanks are installed for collecting and holding reused water, ensuring they are sealed and safe. Moreover, filtration systems are being implemented to treat greywater or rainwater before use, ensuring it meets safety standards.
  4. All systems comply with local health and environmental regulations regarding water reuse.
Water audit team monitors the quality of stored water regularly to ensure it remains safe for intended uses and create a maintenance plan for storage tanks and treatment systems to prevent contamination and ensure efficiency.
2. On-campus rainwater collection and treatment system
Navoi State University has introduced a rainwater harvesting system as part of its water conservation measures. Reservoirs are positioned across the campus to collect runoff from rooftops, sidewalks, and other surfaces. The gathered water is then directed to an automatic purification system, which filters out dust, organic particles, and other impurities. Once cleaned, the water is reused for practical purposes such as irrigating gardens and green areas within the university grounds, as well as meeting sanitary needs in campus buildings, including toilet flushing. This approach reduces dependence on treated water and supports sustainable resource management.
3. Water treatment pumps 
At Navoi State University (NSU), water treatment pumps have been installed as part of the university’s recycling and environmental sustainability programs. These advanced systems help purify and reuse wastewater generated from laboratories, dormitories, and other facilities. By filtering and treating used water, the university significantly reduces water wastage and minimizes its environmental impact. The treated water is safely reused for irrigation, cleaning, and technical purposes around the campus. This initiative demonstrates NSU’s commitment to sustainable resource management, promoting eco-friendly practices and efficient water recycling as part of its long-term goal to build a green and environmentally responsible university
4. Irrigation
One of the most effective uses of stored water on campus is irrigation. Navoi State University maintains gardens, trees, and decorative green areas that require regular watering, especially during dry months. Instead of relying on treated potable water, stored rainwater or recycled greywater can be channeled into drip and sprinkler systems to keep plants healthy. This approach reduces water loss from evaporation and runoff, while also lowering utility bills. In the long run, efficient irrigation supported by stored water ensures the campus landscape remains both eco-friendly and cost-effective.
5. Cleaning Purposes- Vehicle Washing
Maintaining a clean and welcoming environment across sidewalks, courtyards, and student gathering zones requires a substantial amount of water. Traditionally, treated water is used for these purposes, but stored water offers a far more sustainable alternative. Using harvested or recycled water for cleaning pathways, floors, and open areas helps preserve high-quality drinking water for essential needs such as cooking and hydration. It also demonstrates the university’s commitment to responsible resource allocation, ensuring that every drop of treated water is used where it is most needed.
NSU operates a number of vehicles, including buses for student transport, official cars, and maintenance equipment. These require regular washing to ensure safety, cleanliness, and functionality. Stored water can easily be directed toward designated washing points, reducing the demand for potable water. Over time, this practice would save thousands of liters of fresh water each year. By making this switch, NSU not only cuts costs but also provides a clear example of how institutions can adopt simple, practical measures to support conservation.
