Community Drainage Design and Effect Analysis based on Sponge City Concept——Case study of a residential project in Suqian City
Taking a newly built sponge community in Suqian City as an example,the concept of"sponge+"is deeply integrated into the scheme design of the new community,and the ecological drainage system is systematically constructed with rainwater runoff control,runoff pollution reduction and rainwater resource utilization.All the roof rainwater is collected into the rainwater storage tank,which is used for daily greening watering and road washing.The ground rainwater enters the sponge facility to achieve natural accumulation,natural penetration and natural purification.Through the effective combination of sponge facilities and municipal facilities,the investment of drainage facilities is greatly saved,the rainwater resources are effectively recycled,and the living environment of the community is improved.After the construction,the community has effectively coped with multiple heavy rainfall tests,setting a good demonstration benchmark for the construction of livable and resilient city.
