Chizhou, one of the first group of sponge pilot cities, is rich in water resources. As a small and medium-sized city along the Yangtze River, it has many obvious problems caused by urbanization, such as waterlogging, accumulated water and saturated development.
In the renovation and reconstruction project, a method for treating both sponge city and polluted river is comprehensively used to transform an "urban enclave" into a constructed wetland park with daily natural features, and the original polluted and malodorous water body into a water-engaging open space with a stable water quality of Class IV all the year round. It has made an exemplary attempt on the topic of black and malodorous water treatment in the city center.
Overall of the project
This project is at the low elevation of the region. The place where the project is located belongs to the old city with high-density development, which has a combined sewer system. The water body in the project area was originally a pond left by the abandoned moat, which was also one of the ten polluted and malodorous water bodies in Chizhou. The import of a large amount of discretely-discharged waste water from the surrounding area had resulted in a harsh environment in this place. Additionally, there is a problem of water accumulation in the north community all the year round.
The project focused on how to, firstly, turn this small place into a water-engaging open space with daily natural features, which could be accessed and used easily every day, thus turning a negative space into a positive and participatory space; secondly, improve water quality, build a sponge-like constructed wetland, and solve the problem of rain and flood management in the area.

The main entrance of the park, located on Qiupu West Road in the south, has limited dimension due to the restriction that the facilities on the east side of the entrance cannot be relocated. Under this restriction, the effort will be maximized as far as possible to create an “empty” square, thus making the heritage park open its arms and embrace the citizens to explore this modified enclave in the city.
The vertical revetment between the existing hospital and the water body on the west side is just like a vertical crack that interrupts the continuation of the green basement. In order to form a water-engaging loop, emergent aquatic plants and green island are used to realize the green connection on the west side of the park. The water-engaging trail is independent of the revetment, winding in the plants, creating ecological poetry of constructed wetland together with the intermittent resting terraces and simple white porch.

The entrance connecting the dormitory of Xinhua Bookstore on the north side has been maintained for the convenience of residents. People would face the outstanding platform after passing through the entrance, on which they could view the whole place as their own back garden.

The space on the east side of the park is narrow, and the landscape platform designed to solve the height difference also has the function of primary purification of road rainwater. The soil in the platform is designed with specific substrate according to the water quality of Chizhou.

After renovation and modification, the park has become an accessible waterfront activity space, effectively increasing the regional vitality and upgrading the environment of the old city, and providing a venue for ecological education in the urban area. Polluted and malodorous water body has met the standard of stable Class IV. By restoring lake habitat and improving the diversity of plant communities and animals, the lake has become an important habitat for wild birds such as wild ducks and egrets.

It is a very beneficial attempt to transform the polluted and malodorous water body into a constructed wetland park with daily natural features. Compared with the wetland park in the suburbs where you need to drive, the place with such daily natural features that can be accessible after meals is more precious for people.
