Water Use Efficiency

An-Najah National University is committed to sustainable practices in construction and building management, with a particular focus on minimizing water use. The university adheres to the Palestine Green Building Guideline 2024, which provides comprehensive standards for enhancing water use efficiency in all building projects. This guideline plays a central role in the university's approach to environmental responsibility, specifically in terms of reducing water consumption and optimizing resource use.

1. Water Use Efficiency in Building Projects:
   In line with the Palestine Green Building Guideline, the university applies various strategies to improve water use efficiency in both new constructions and the rehabilitation of existing buildings. The guideline emphasizes the following key principles:

   • Reduction of Fresh Water Consumption:
     The university implements water-saving fixtures and systems in buildings, such as low-flow faucets, dual-flush toilets, and efficient irrigation systems. These measures are designed to significantly lower the demand for fresh water across the campus.

   • Minimization of Wastewater Production:
     In addition to reducing water usage, the university is committed to decreasing the production of wastewater. This is achieved through the implementation of greywater recycling systems and other innovative solutions that help reuse water for non-potable purposes, such as irrigation and cooling.

2. Commitment to Green Building Standards:
   An-Najah National University ensures that all new construction projects and any rehabilitation of existing facilities strictly follow the Palestine Green Building Guideline 2024.This guideline provides a clear framework for sustainable design and construction, with a strong focus on water efficiency and conservation.

3. Toilet (flush valve) with a flow rate of no more than 4.8 liter/flush

4. A dual-flush flush toilet with a flow rate of 3 liters/flush for the first flush and 6 liters/flush for the second flush.

5. A rinser with a flow rate of no more than 4.5 liter/min at a pressure of 3 bars.

6. Urinal with a flow rate of no more than 1.9 liter/flush at a pressure of 3 bar.

7. Washbasin faucets with a flow rate of no more than 4.5 liter/minute.

8. Kitchen taps with a flow rate of no more than 8.5 liter/minute.

9. Shower with a flow rate of no more than 7.6 liter/min

10. The use of pot rinse valves in restaurants and hotels with a flow rate of no more than 6 liters/minute.

11. A domestic washing machine with a flow rate of no more than 8.75 liter/kg of laundry.

12. A household dishwasher with a flow rate of no more than 22 liters per cycle, or 15 liters per cycle for small models.

3. Ongoing Efforts and Future Plans:
   As part of its broader sustainability strategy, the university is continuously working to further enhance water conservation efforts by exploring new technologies and innovations in building design. These efforts aim to:

   • Further reduce fresh water usage.

   • Lower the campus’s environmental footprint.

   • Integrate more water reuse systems, especially in landscape management and operational processes.

By applying these standards and practices, An-Najah National University demonstrates its commitment to sustainable development and environmental stewardship, contributing to the efficient use of natural resources and the preservation of water for future generations.
