Engineering Application of Integrated Rainwater Infiltration and Drainage System

Integrated rainwater infiltration and drainage system is an effective technical measure for rainwater utilization in buildings and residential areas.Combined with the practical application situation of Yongyou software,main technical measures and design methods of this system are analyzed with emphasis on the impact on surface runoff.Integrated rainwater utilization facilities can substantially reduce the rainwater discharge and have a significant influence on the planning and design of urban drainage system.In the same design period,the urban rainwater pipeline diameter can be properly reduced.
