Abstract: In terms of water conservation in cities, Xi'an has implemented an IC card water control system in more than 200 enterprises, and at the same time, vigorously promoted intelligent water control systems and sewage treatment recycling models in colleges and universities. Currently, water-saving facilities have been installed in more than one third of colleges and universities in Xi'an. Since 2004, all 12 newly built university campuses have constructed sewage treatment and reuse systems, which can save about 18 million cubic meters of water resources every year.
