During 10 years construction and development of Tianjin Eco city, through drawing lessons from Singapore’s experience and adapting measures to local condition, beneficial explorations on the construction of standardization system of water treatment, water security guarantee, improvement of water environment, optimization of water resources and other aspects have been made in Tianjin Eco-city: the Guidelines for Safe Water Supply and Emergency Response Water Saving and Non-traditional Water Resources Management and Utilization were formulated, and The Index System of Sino-Singapore Tianjin Eco-city was first established in China, thus forming the system of Sino-Singapore Tianjin Eco-city Water Management Guidelines.The stock pollution of 2.56 km2 wastewater reservoir was controlled, the catchment area was implemented. Then, the permeable surface was ensured not less than 45% and other relevant low-impact development strategy, and the water supply monitoring mechanism was built to ensure water security. Through upgrading wastewater discharge standards to meet the water quality and quantity of ecological recharge water, strengthening ecological purification of runoff into rivers, connecting water system and promoting water circulation to improve water environment, carrying out water balance matching to increase the science of water application decisions and optimize allocation of water resources, now the utilization rate of non-traditional water resources of Tianjin Eco-city has exceeded 60%. Meanwhile, Tianjin Ecocity implemented a closed-loop intelligent water management system that integrated water quality monitoring, early warning and emergency response. At present, an improving scientific water management model has been formed in Tianjin Ecocity, which can provide reference for other urban water management.
