The invention relates to an urban drainage, water replenishment and 
water exchange pump 
station hub which is designed for solving the technical problems of the poor management of similar pump stations, the poor urban drainage, water replenishment and 
pollution control effects and too high reconstruction cost. The hub comprises a water replenishment pump 
station and a water drainage pump 
station, wherein the water replenishment pump station is located on an outland river on the side of a 
main river channel, and the water drainage pump station is arranged in an urban inland river. The urban drainage, water replenishment and 
water exchange pump station hub is characterized in that an 
underground pipeline for achieving communication of the two pump stations is arranged between the water replenishment pump station and the water drainage pump station, and the water replenishment pump station and the water drainage pump station are provided with an outland river 
sluice and an inland river 
sluice correspondingly, and are each provided with a 
control system. The 
underground pipeline design can save land, and meanwhile, when the 
water level of the inland river is too high, drainage is carried out through the water drainage pump station; when the 
water level of the inland 
river network is too low, water is supplemented through the water replenishment pump station and the 
underground pipeline; and when the inland 
river network is polluted, water is exchanged through the water drainage pump station and the underground pipeline. The structure is simple, the design is reasonable, the construction cost is low, the investment is small, and the effects of drainage and 
pollution control are good; and the urban drainage, water replenishment and 
water exchange pump station hub is suitable for new construction and reconstruction and upgrading of urban pump stations.
