Water Reuse Measurement at Walailak University

Walailak University, through the Division of Waste Management Landscape Architecture and Environment, is responsible for measuring the volume of reused water treated from wastewater across the campus and all outlets, such as academic buildings, dormitories, the building group of the Center for Scientific and Technological Equipment, lecture buildings, and so on.

In 2022, the volume of reused water at Walailak University was 490–1,050 cubic meters per day, measured by pumping systems and water meters. Meanwhile, Walailak University treated wastewater across the campus in the amount of 700–1500 cubic meters per day. The treated wastewater was measured by flow meters.

Walailak University has been using reused water to implement university activities in order to reduce the impacts of freshwater sources’ diversion on campus and the ecosystems surrounding the university and ensure that the treated wastewater at WU is practical and not contaminated by chemical substances. Here are the activities for using reused water:

1. Watering plants and all landscapes on campus by using fire sprinkler systems
2. Watering plants in communities surrounding the university and other areas with water scarcity, especially in the summer
3. Aquaculture activities
4. Vehicle washing
5. Road cleaning
6. Utilizing the treated wastewater to reduce the temperature of waste incinerators so that the room temperature will not be too high
