For purpose of promoting the construction of reclaimed water market, this paper took Xi'an city asexample by researching on its development process of reclaimed water market. From the perspective of evolutionary game theory, we studied the equilibrium and evolutionary paths for a tri-game between government, manufacturers and consumers in the reclaimed water reuse market. Our analysis showed that the evolutionary process of reclaimed water reuse market consisted of four stages and the system could evolve to different equilibriums at different stages. Support from government can significantly improve the amount of reclaimed water treatment and recycling in the initial stage. In the subsequent stages of development, the participation of manufacturers and acceptance of consumers should be improved by distributing financial subsidies, improving utility of using reclaimed water, reducing utility of tap water, increasing profit of reclaimed water manufactures and reducing cost of government management.
