Measurement Reuse Water 2024
Introduction
This report provides a comprehensive account of water reuse and recycling practices at An-Najah National University (ANNU) for the year 2024. It outlines the total volume of reused and recycled water, the systems established for wastewater collection and treatment, and the various applications of reclaimed water across the University’s campuses. The findings reflect ANNU’s steadfast commitment to sustainable water resource management, showcasing its ongoing efforts to close the water loop, optimize resource efficiency, and minimize reliance on freshwater sources.
Through continuous measurement, monitoring, and system expansion, the University demonstrates a proactive approach to reducing its environmental footprint and advancing campus-wide sustainability.
Measurement of Reused and Recycled Water Across the University
An-Najah National University systematically measures the volume of water reused and recycled across all its campuses. The University has developed an integrated water management system that includes collection, treatment, and redistribution of wastewater for safe and productive reuse.
Measurement Process
-
Water meters and flow sensors are installed at strategic points within the wastewater purification and storage systems.
-
Data on reused water volumes are collected monthly, verified by the Facilities and Sustainability Units, and compiled into an annual report.
-
The University ensures that all measurement systems comply with Palestinian environmental standards and ISO guidelines for sustainable water management.
Sources of Reused/Recycled Water
The primary sources of reused or recycled water at ANNU include:
-
Treated Wastewater from the Faculty of Agriculture’s Wastewater Purification Plant;
-
Greywater Reuse Systems in laboratories and selected campus buildings;
-
Rainwater Reuse from collection tanks used for non-potable applications such as irrigation and cleaning.
Total Volume of Water Reused or Recycled
During the 2024 reporting period, An-Najah National University recorded the following volumes of water reused or recycled:
Total Reused/Recycled Water Volume (All Sources): 2,000 m³
This figure represents the total amount of treated wastewater, greywater, and collected rainwater that was reused across all campuses during the reporting year.
Wastewater Purification and Reuse – Faculty of Agriculture
The Faculty of Agriculture operates a dedicated wastewater purification plant that treats wastewater generated from laboratories, student facilities, and fish farm.
Water Recycling Process
-
Collection: Wastewater is collected through a network of underground pipelines.
-
Treatment: The purification unit applies physical, chemical, and biological treatment processes.
-
Storage: Treated water is stored in specialized tanks within the Faculty’s premises.
-
Reuse: The purified water is reused for irrigating experimental farms, orchards, and green areas within the Faculty.
Total Volume of Treated and Reused Water: 800 m³
This process significantly reduces demand for fresh groundwater, promoting circular water use and supporting sustainable agriculture within the University.
Greywater Reuse Systems Sports Complex
A pilot greywater recycling system has been implemented across several of the University’s Sports Complex facilities, including locker rooms, shower areas, and washbasins, to treat and reuse water for irrigation and cleaning purposes.
The reused greywater is primarily utilized for:
-
Toilet flushing.
-
Cleaning sports grounds.
-
Irrigating landscaped spaces near academic buildings.
Total Volume of Greywater Reused: 1200 m³
This initiative serves as a practical demonstration of sustainable water management, reducing freshwater demand and paving the way for large-scale adoption of greywater reuse across other University facilities.
Rainwater Reuse and Non-Potable Applications
Rainwater collected from campus rooftops and courtyards through the rainwater harvesting system is also considered part of the University’s reuse initiative, as it reduces the use of fresh groundwater for non-drinking purposes.
Collected rainwater is reused for:
-
Garden and landscape irrigation;
-
Floor and surface cleaning;
-
Cooling and fire suppression systems.
Total Volume of Reused Rainwater: 7,000 m³
This approach supports ANNU’s integrated model of rainwater recovery and reuse, ensuring that natural precipitation contributes directly to water conservation goals.
Campus-Wide Water Reuse Management Framework
An-Najah National University has established a structured management framework to ensure the long-term sustainability of its water reuse systems:
-
Monitoring and Data Collection: Monthly measurements from each water reuse system are aggregated into the University’s environmental database.
-
Maintenance and Quality Control: Regular inspections are conducted to ensure water quality and safety in accordance with the Palestinian Environmental Quality Authority standards.
-
Sustainability Integration: Reuse data are incorporated into the University’s Annual Sustainability Report.
Conclusion
An-Najah National University demonstrates leadership in sustainable water management by implementing and expanding systems for wastewater treatment, greywater reuse, and rainwater utilization.
By measuring and documenting all forms of reused water, ANNU not only reduces its dependence on groundwater resources but also contributes to national efforts in climate resilience and water conservation
