Miancheng City Rainwater Collection Pool

Rainwater Harvesting Module Sponge City Rainwater Collection Pool  addresses the following issues: research on modern stormwater control design theories and modeling software; or the introduction and implementation of local stormwater control design standards and technical guidelines; transforming experience-based, extensive design into rigorous, detailed, and scientific design.

Technical challenges to be addressed include: actively promoting low-impact development technologies, enhancing rainwater utilization, advocating for source reduction, and building sponge cities; Rainwater Harvesting Module Sponge City Rainwater Collection Pool  emphasizes theoretical calculation and analysis of drainage capacity of storm inlets, such as service area, location, spacing, quantity, and numerical analysis of water accumulation near storm inlets; additionally, China currently lacks mathematical models for splash velocities of various storm inlets. To cope with major storm events, it is necessary to design and verify, clarify the drainage capacity of streets, and integrate different functional land uses in cities for stormwater management, biodiversity habitats, public recreation, and visual landscapes; reduce urban stormwater runoff and peak runoff by utilizing natural depressions for storage and reducing the proportion of impervious surfaces;

Minimize the cost of drainage infrastructure construction. Rainwater Harvesting Module; Sponge City Rainwater Collection Pool; Based on advanced international experience, the principles of green stormwater control engineering planning and design can be summarized as: source reduction, collection and infiltration, safe conveyance, storage and utilization, and controlled discharge. China's research and practice in stormwater storage are still in their infancy, mostly limited to urban community scales and focused on engineering facilities, with relatively insufficient macro-scale stormwater management planning aimed at integrated effects of stormwater management, water quality protection, and landscape. Cities should prioritize retaining limited rainwater, making greater use of natural forces for drainage, and building sponge cities that naturally store, infiltrate, and purify rainwater.

Therefore, the construction of sponge cities is an important measure for implementing ecological civilization. Rainwater Harvesting Module; Sponge City Rainwater Collection Pool is an effective means to achieve multiple goals such as restoring urban water ecology, improving urban water environment, and enhancing urban water security. It should be scientifically planned and put into practice.
