Water Reuse Measurement (6.4.2)

Measurement and reporting of reused water volumes to support sustainability planning.

Introduction:

Al-Ahliyya Amman University (AAU) implements an integrated and highly structured framework for measuring, documenting, and reporting water reuse across all campus facilities. This system ensures that every stage of water recovery—from collection to treatment to reintegration—is monitored with precision, forming a core component of the university’s long-term sustainability planning.

The measurement process follows a unified governance model supported by officially approved institutional policies and procedures that define the methodology, quality assurance requirements, and operational standards necessary to ensure consistency and reliability across all units.

Within this framework, AAU conducts regular monitoring cycles in which reused water volumes are evaluated, validated, and incorporated into the university’s Sustainability Dashboard and Annual Sustainability Report. This approach enhances transparency, strengthens data reliability, and enables evidence-based decision-making regarding water management, infrastructure development, and campus operations.

The continuous measurement of reused water supports AAU’s commitment to resource circularity and reinforces progress toward SDG 6.3 by improving water quality management and SDG 6.4 through enhanced water-use efficiency. By adopting a rigorous, policy-driven measurement system, the university demonstrates sector-leading practices in sustainable water governance and contributes meaningfully to responsible environmental stewardship within the higher education sector.

5. Student Research and Capacity Building on Water Monitoring

The Hourani Center for Applied Scientific Research involved engineering students in projects developing IoT-based measurement prototypes for future water reuse tracking.
This strengthens innovation capacity and student engagement in sustainability research.

Impact Evaluation & Development Plan

Performance Evaluation
- Efficiency increase: 56% growth in reuse volume since 2022
- Reuse coverage: 100% of irrigation and cleaning operations supplied by reused water
- Reporting accuracy: 100% data validated and included in sustainability reports
Development Actions
Action 1: Implement automated data logging through smart meters connected to central servers for real-time tracking.

Action 2: Expand metering coverage to include rainwater harvesting systems and greywater reuse pipelines.

Action 3: Develop a monthly Water Reuse Performance Bulletin published by the Sustainability Center.

Action 4: Collaborate with local water authorities to align data formats with national environmental reporting frameworks.

Action 5: Introduce AI-based analytics for trend prediction and sustainability planning optimization.
Benchmarking & Best Practice
Adopted Practice: Aligned with ISO 14046 Water Footprint Standards and Jordan’s National Water Strategy (2023–2040) requiring quantitative monitoring of reused water.

Local Adaptation: AAU’s reuse measurement system integrates digital metering and manual verification logs adapted for Jordan’s semi-arid climate, ensuring data reliability and continuity even during seasonal fluctuations.

Future Benchmark Goal (by 2028):
- Achieve full smart metering coverage of all reuse sources and pipelines.
- Increase total reuse volume by 50% compared to 2024 baseline.
- Integrate measurement data directly with carbon and sustainability performance indicators.
Institutional Integration Summary

Water reuse measurement at AAU is a core part of its sustainability governance, combining data management, operations, and scientific verification.
The Sustainability and International Ranking Center supervises data analytics, while the Facilities Department handles meter readings and system maintenance, and the PDRC verifies quality.

This structure ensures evidence-based sustainability planning, allowing AAU to make informed decisions that optimize resource use and minimize environmental impact.
Through transparent data, technological innovation, and interdisciplinary cooperation, AAU demonstrates measurable progress toward SDG 6.3 (Reuse and Quality) and SDG 6.4 (Water Efficiency), positioning itself as a national leader in quantitative water sustainability management.
