- Priority will be given to the transformation of water-savingappliances and the selection of Class 1 water efficiency appliances.
- Strengthen refined management and strictly implementpipeline leakage control. The water-saving potential of pipelineleakage control is very great, and universities should choose suitablemeasures for leakage control based on their own actual situation.For universities with high water volume and frequent leakage, asmart water information platform can be built to quickly respond toabnormal water usage and repair it in a timely manner; Foruniversities with low water volume, new pipelines, and scarce funds,manual meter reading can be used for management.
- Timely carry out reclaimed water reuse. For universities withlarge green areas, high landscape water usage, and a wide range ofmiscellaneous drainage reuse, the water saving capacity of thereclaimed water reuse system is very considerable, and in highreuse cases, investment costs can be quickly recovered. In responseto the issue of large initial investment amounts, the government canobtain green financial support from financial institutions for watersavingprojects through the recently launched "water-savingbenefits" business. To address the issue of low carbon emissionreduction benefits, further optimization of the process can be carriedout to reduce energy consumption and reduce carbon emissions.
- Timely carry out rainwater reuse. The amount of rainwaterreuse is influenced by various factors such as rainfall, catchmentarea, and reservoir volume. A reasonable rainwater reuse systemshould be designed based on the actual situation. Multiple ways canbe explored to utilize rainwater, combining the transmission andstorage of rainwater with campus landscape and ecologicalenvironment construction, further reducing carbon emissions,building green campuses, and achieving sustainable development.
