As a large-scale urban municipal project, the underground drainage pump station needs to reserve dozens of inspection ports on the ground for the maintenance and hoisting of large equipment, and needs to be equipped with access for large vehicles. When the greening Department of Jing'an District took over the greening project of the water pump station, it did not continue the traditional old scheme of discharging potted flowers, but introduced the practice of foreign postmodern industrial site Gardens -- building tall trusses to replace cranes to leave space for greening; The deconstruction module art wall with a sense of sculpture with a height of three floors is cleverly erected around it; The inspection port reserved for equipment maintenance of water supply and drainage pump station has also become a movable anti-corrosion wood floor. Above the drainage pump station, there is a modern display space. "In the future, fashion shows, fashion exhibitions, art galleries and other activities will be held here," Huang caidi, director of the Greening Bureau of Jing'an District, told reporters. "As soon as the Butterfly Bay Garden was completed, many fashion studio walk show reservations were received."

The underground is a large municipal drainage pump station of more than 5000 square meters, and the ground is a large modern urban garden of more than 8000 square meters. The Butterfly Bay Garden, located at the intersection of Taixing road and Kangding Road on the Bank of Suzhou River in Jing'an District, skillfully combines the two organically and artistically, creating a new urban waterfront landscape full of artistic sense. Butterfly Bay Garden has been open to the public free of charge a few days ago, and has been widely praised by the public and experts.

The drainage pump station inevitably has peculiar smell, especially in summer, Butterfly Bay Garden built a stone array drop pool in the front of the park square, and an array pool in the west to purify the surrounding air through the negative ions generated by the flow circulation of cascade water body. The pool extends two arc art landscape walls to the north, which cleverly hides the ground facilities of the drainage pump station. Butterfly Bay is a hydrophilic platform and corridor along the Suzhou River, dotted with bamboo forest, tall magnolia, Washington palm, beech, ginkgo and other plants. The park is rich in plants, landscape walls, trusses, porches, cascades and hydrophilic platforms, forming a dynamic and static, light and shadow changing, virtual and real contrast, and becoming a landmark scenic spot along the Suzhou River.
