Water Reuse Policy

The University of Warith Al-Anbiyaa  has established a formal institutional framework for water conservation, water reuse, recycling, and sustainable water-resource management through its Water Conservation Policy (UOWA-WCP-2025-v2.0).

The policy was originally established in January 2020 and has undergone periodic institutional review and revision, most recently in March 2025 (v2.0), to strengthen and maintain the university's institutional framework for water conservation, water reuse, recycling, monitoring, and sustainable water-resource management.

The policy is governed through the university's institutional sustainability governance structure, including the University Council and the Sustainable Development Committee, and is subject to periodic review.

Policy Commitment to Water Reuse

Water reuse and recycling are identified as important components of UOWA's water-management approach. The policy establishes measures to:

• maintain and improve wastewater treatment systems;
• reuse appropriately treated wastewater for suitable non-potable purposes;
• increase the use of treated wastewater for campus irrigation;
• expand rainwater harvesting;
• support water recycling and resource recovery; and
• reduce dependence on freshwater through the beneficial reuse of suitable water sources.

Wastewater Treatment and Reuse

Section 4.1 of the policy establishes institutional measures for wastewater treatment and reuse. The policy requires the university to maintain and upgrade wastewater treatment systems to support the safe reuse of treated water for non-potable applications.

The policy establishes a target for treated wastewater to supply 70% of campus irrigation demand within three years. This figure represents an institutional policy target and is therefore reported separately from the university's measured water-reuse performance.

Suitable treated water may be used for designated non-potable purposes, including:

• landscape irrigation;
• toilet flushing; and
• cooling-tower make-up water, where technically appropriate.

Rainwater Harvesting and Resource Recovery

The policy also provides for the expansion of rainwater-harvesting systems and the maintenance of water-absorption areas and recharge wells.

These measures form part of UOWA's broader institutional approach to reducing freshwater demand, increasing water reuse, and promoting the sustainable and circular management of campus water resources.

Governance, Monitoring and Accountability

Implementation of the Water Conservation Policy is overseen through UOWA's institutional sustainability governance arrangements.

The policy provides for monitoring of water use, water efficiency, recycling, and related performance indicators through university records and monitoring systems. Relevant performance information is reviewed as part of the university's ongoing sustainability-management process.

Policy Revision and Update History

Version / Update	Date	Key Development
v1.0	January 2020	Initial water-conservation framework and governance
v1.1	October 2021	Updated water-efficiency provisions and wastewater-reuse objectives
v1.2	September 2023	Further development of smart irrigation, drought-tolerant landscaping and rainwater-harvesting measures
v2.0	March 2025	Updated water-management metrics, standards references and water-reuse targets

Policy Target and Measured Performance  Clear Distinction

For transparent reporting, UOWA distinguishes between its policy commitment and its measured water-reuse performance:

• 70% = the policy target for the proportion of campus irrigation demand to be supplied by treated wastewater within three years.
• 82.76% = the proportion of treated wastewater reused in 2025, calculated from 120,000 m³ reused out of 145,000 m³ treated.

These percentages represent different measures and use different denominators; therefore, they should not be presented as interchangeable.

The 70% figure is a policy target, whereas 82.76% represents the 2025 measured proportion of treated wastewater that was reused.

Conclusion

The UOWA Water Conservation Policy provides a formal institutional framework for water conservation, wastewater treatment and reuse, rainwater harvesting, recycling, and resource recovery.
