Core Viewpoint - Chongqing is actively implementing sponge city construction, utilizing various measures to enhance urban water management and reduce flooding risks through innovative designs and infrastructure improvements [1][2][3]. Group 1: Sponge City Construction - Chongqing has completed 2,055 sponge city projects, with 535 compliant drainage areas covering 845.8 square kilometers, accounting for 46.2% of the urban built-up area [1]. - The city employs techniques such as infiltration, retention, storage, purification, utilization, and drainage to manage rainwater effectively [1]. Group 2: Rainwater Gardens - Rainwater gardens, referred to as "sponge cells," are designed to collect, retain, and purify rainwater, contributing to groundwater recharge and landscape irrigation [2][3]. - These gardens utilize native plants that can withstand flooding and drought, enhancing their ability to retain rainwater [2]. Group 3: Infrastructure Innovations - The cloud lake in the data valley has a storage capacity of approximately 4,000 cubic meters, controlling rainwater runoff for an area of about 200,000 square meters [3]. - The integration of permeable pavements and bioretention areas along roads helps to slow down rainwater runoff and improve water quality [3]. Group 4: Sports Facilities Adaptation - The Daitianwan Sports Center has been retrofitted with a rainwater reuse system, allowing for the collection and utilization of rainwater for field maintenance and sanitation [4][5]. - Green roofs have been introduced in indoor venues to enhance rainwater retention, creating over 3,000 square meters of green space [5]. Group 5: Industrial Applications - The Chongqing Chemical Industry Co., Ltd. has implemented sponge facilities in its factory area, including 14 rainwater gardens to manage stormwater and improve the working environment [6][7]. - The integration of rainwater gardens with parking lots in Liangping District enhances both stormwater management and aesthetic appeal [7]. Group 6: Future Developments - Chongqing plans to continue its sponge city initiatives by leveraging IoT and big data technologies, aiming to create a more livable and intelligent urban environment [7]. - The city is also focused on developing a "sponge industry chain" to support local enterprises in creating suitable sponge technologies and products [7].
