Abstract: Due to water shortages, many districts and cities have started reusing wastewater as an inexpensive supplemental source of water. This study was conducted to evaluate the suitability of various sites for construction of decentralized wastewater reclamation facilities, to identify suitable conditions for reclaimed water reuse in various industries, and to provide helpful information for the formulation or revision of urban wastewater reclamation policies. To accomplish this, the factors influencing the construction of wastewater reclamation facilities were analyzed taking Beijing as an example. In addition, the suitability of wastewater reclamation by water consumers from government institutes, colleges and hotels in Beijing was evaluated after consideration of the water consumption of several consumers in each of these industries. The results indicate that most government institutes and one- and two-star hotels are not suitable, while most hotels of three-star or higher level and most colleges are suitable, for the construction of wastewater reclamation facilities.
