A sustainability strategy of integrated highway wetlands for urban water management in China

Abstract

Abstract The rapid expansion of urban space has caused many problems all around the world. This is especially true in China, where we need to face challenges such as limited spaces, wastewater treatment, decreasing water resources, ecological preservation, and so on. In the management of urban water, an economic, environmental, and social balance needs to be. The aim of this study was to develop a freeway strategy of Integrated Constructed Wetlands to achieve this balance. This strategy combined several disciplines of civil engineering, ecology, landscape design, and agricultural irrigation, and this conceptual idea will be demonstrated through a design for Huai’an city in Jiangsu province, which sits on the East-route Water Transfer Project of China. The project consists of surface flow wetlands, ecotype corridors, retention facilities, and stabilization ponds. Importantly, it is designed beside the Ning-Lian freeway that goes around the city. The whole system could treat effluents from city and wastewat...
