This chapter analyzes China’s water environment quality and governance status from the perspective of China’s water environment management policy，mainly from the water pollution prevention action plan and the “13th Five-Year Plan” of water environmental protection. Generally speaking，China’s water environment is generally improving，but the Yellow River，Songhua River，and Huaihe River Basins still have light pollution，and the rivers，seas，and Liaohe River basins have moderate pollution. Water environmental protection work still needs to be strengthened. In addition，black and odorous water bodies around Governance results are uneven，and the governance market has huge potential. In order to solve the problem，this chapter analyzes the treatment project of China Construction Water & Environment Co.Ltd of China Pingshan River，and introduces its “3 + 1” water management ideas of “pollution control，flood prevention，ecological restoration” + “urban construction” and integration of space and business information. The project can provide a reference for water environment treatment in other cities in China.
