    Let’s follow the steps of the media to have a look!
     
     

    The first stop: Yuhang Tanghe city management station, a new service that warms the hearts of the people and provides convenience for the people
     

    At 9 a.m., the media reporters arrived at Yuhang Tanghe city management station on time. The length of the river course regulated by BEWG in Yuhang Tanghe River is 8340m, and the main construction contents are revetment reconstruction, comprehensive pipeline construction, bridge construction, landscape greening and supporting facilities engineering. Two urban management rest stations have been built along the line, with the integration of urban management, Party and mass construction, etc., which were opened to the public in November 2020.
     

    Gu Chaoguang, general manager of the Operation Branch of Beikong (Hangzhou) Environmental Engineering Co., Ltd., introduced the facilities and services of Yuhang Tanghe urban management rest stations. The convenient facilities, Party building alliance, etc. have been highly praised by the media reporters.
     

    The urban management rest stations provide services for the front-line personnel engaged in urban management including sanitation, law enforcement, parking fees, municipal administration, greening, river courses, etc. In addition to leisure tables and chairs, air conditioners, refrigerators, microwave ovens, water dispensers and other hardware facilities, medical boxes, mobile phone charging device, newspapers and periodicals, needle boxes and other supporting services are also provided in the stations. A Party building alliance is also established for the stations, which integrates such Party building resources as BEWG and the Future Science and Technology City, etc., giving full play to the fighting fortress role of grass-roots party branches and the vanguard and exemplary role of the Party members to actively provide services to sanitation workers and the general public within their capabilities.
     

    The second stop: the south river water system to display new water control technology
     

    At 10 a.m., Zhou Xuhui led the media to visit Xinqiao Port and Hongwei Port of the southern river water system. The sub-projects of comprehensive regulation of water system in the south includes 22 river courses, with a regulated drainage area of about 24.76km², which mainly covers drainage system reconstruction, ecological restoration, living water and smart water projects in the urban area of old Yuhang. 
     

    At the scene, on the river near Xingang bridge, an unmanned ship was patrolling. The staff also showed the new technology of ecological water control of the project. The mussels fished out of the river attracted the strong attention of the on-site media, “I didn’t expect that there were mussels that could produce pearls in the landscape river of Hangzhou! I also didn’t expect that small mussels could play a big role, which could not only purify water, but also improve economic benefits. It really makes the best of both worlds!”
     

    Xinqiao Port and Hongwei Port are important rivers located in the Future Science and Technology City of Yuhang District. Along the banks are important parks such as the Provincial Party School, Haichuang Park, Alibaba, etc. Before treatment, the water of Xinqiao Port and Hongwei Port was turbid, and the cross section of Haichuang road exceeded the standard continuously, and the water quality was inferior to Class V all year round. As the leading unit of the PPP project for the comprehensive treatment of the water environment in the Yuhang Tanghe River Basin, BEWG fully serves the improvement of the water environment of the Future Science and Technology City. Relying on rich experience in river and lake management, BEWG has systematically investigated the water quality, sediment, river outfall, etc. of Xinqiao Port and Hongwei Port by using unmanned ship monitoring technology. On this basis, it selects water environment restoration and biological chain targeted water treatment technologies, and makes full use of the biological chain built by aquatic plants, microorganisms, microalgae, mussels, fish, etc. to gradually purify the water body.
     

    After three months of treatment, at the beginning of April 2021, the water quality of the main sections of Xinqiao Port and Hongwei Port continued to improve, and the mussel-based biological chain targeted treatment technology began to play a role. After test by a third-party testing unit entrusted by the Future Science and Technology City Management Committee, the river water quality has maintained Class IV for a long time, with remarkable treatment effect.
     
     
     

    The third stop: Phoenix Mountain Park-----new look tells a new story
     

    Near noon, the media came to the last stop, Phoenix Mountain Park. The total land area of the sub-project of Phoenix Mountain Park is 373,000㎡, and the main construction contents include park infrastructure, integrated pipelines, landscape architecture, landscaping and other supporting ancillary works.
     

    Gu Chaoguang made a detailed introduction to the media about the way of soaring beauty before and after the governance of the Phoenix Mountain Park. The once bare mines have disappeared, replaced by a sea of flowers and lush forests.
     

    There were many abandoned mining areas in the Phoenix Mountain Park. According to the current situation of the site, and combined with the needs of people’s livelihood, BEWG has followed the characteristics of “natural traceability and demand superposition” to transform and comprehensively utilize the mining area. The original terrain of the park is affected by mining, and some mountains and rocks are easy to slide, so it is not suitable to build footpaths in the mountains. In addition, since the mining area is deep, a high drop is formed with other areas. In order to facilitate people’s visit, an overhead trestle with a length of hundreds of meters was built along the mountain in the mining area in the east. As a link connecting the east and west mountains, the trestle not only meets the connection of the height difference between mountains, but also meets the tour experience without steps in the whole process on the basis of not damaging the natural resources of the mountain. 
     

    Meanwhile, the mined flat valleys were covered with green to create a flower sea landscape. Some mines were built into a lawn area, and some were built into a forest crossing area to meet the leisure needs of different tourists. It is worth mentioning that the trestle railings are designed as toughened glass that takes into account both tour safety and perception permeability. At night, there are color changing light strips hidden in the handrails on the trestle, so tourists can get themselves in it and experience the night view. Nowadays, the glass trestle has become a well-known “must-visit place”.
