This project is located in the green belt on the west side of Tianjia Park, with a catchment area of about 247.7ha, an effective volume of 14000m3, and a total land area of about 1747m2. This project is an initial rainwater storage tank used for controlling the pollution of initial rainwater runoff in a combined drainage system. The inlet of the storage tank is intercepted from the current DN1000 combined system pipeline on Xi'an Avenue, and the outlet is discharged into the Tianjia Sewage Treatment Plant.
The vacuum flushing system is adopted. In the absence of anyone on duty, the vacuum flushing system can achieve remote monitoring, information integration, automatic flushing, and autonomous circulation. It can effectively flush sediment from the floor of the storage tank into the collection corridor, achieving the effect of cleaning the storage tank.
