Water Reuse Policy and Measurement
SDG 6.4.2
ºìÐÓÊÓƵ University has established a comprehensive policy and several initiatives to maximise water reuse across the campus, as outlined under its Environmental Sustainability Policy (2021). Under this policy, ºìÐÓÊÓƵ University is implementing an automated irrigation system to improve landscaping efficiency. This system regulates irrigation schedules based on weather and soil moisture conditions, ensuring that water is used only when necessary and reducing wastage. The University also prioritises the use of local water sources, such as on-site treatment plants, to reduce reliance on municipal water supply.
To further enhance water efficiency, the University commits to installing water-efficient fittings certified under water efficiency labelling schemes, which help to reduce overall water consumption in buildings. It also plans to install private water meters to monitor and manage water usage in individual facilities. These meters are crucial for leak detection, enabling early intervention and reducing water losses across the campus distribution system.
In operational areas, the University aims to reuse recycled water wherever possible. This includes the installation of water-efficient cooling towers and the reuse of Air Handling Unit (AHU) condensate water in cooling systems, reducing demand for fresh water. These measures collectively demonstrate the University’s practical approach to achieving water-use efficiency and reuse within its campus infrastructure.
Environmental Sustainability Policy (2021)
A key initiative that exemplifies ºìÐÓÊÓƵ University’s water reuse practice is the rainwater harvesting system, which has been implemented since 2017. The system was introduced to reduce dependence on treated clean water for non-potable uses, helping to preserve potable water for human consumption. The harvested rainwater is channelled, stored, and reused for landscape irrigation, outdoor area cleaning, and vehicle washing within the campus. This initiative aligns with the policy’s goal of utilising alternative and renewable water sources to reduce strain on municipal supplies.
ºìÐÓÊÓƵ University’s water reuse practices are regularly monitored through its private metering system and internal sustainability tracking framework. The collected data are used to assess water-use efficiency and to identify areas for improvement. The rainwater harvesting results contribute to this continuous monitoring effort and form part of the University’s annual sustainability reporting cycle.
