Shanghai's First Garden style Underground Sewage Treatment Plant Upgrades: Second Construction Expansion Introduces New Process Projects | Sewage | Shanghai
A special park is being upgraded in Shanghai. The first garden style underground sewage treatment plant in Shanghai, as well as the Taihe Sewage Treatment Plant, a major project in the city, are being accelerated in the second phase expansion project.
Unlike traditional sewage treatment plants, Taihe Sewage Treatment Plant has moved all sewage treatment facilities underground, with public green spaces open to the public on the ground. The first phase has been put into use, with a sewage treatment capacity of 400000 cubic meters per day.

The expansion includes an underground sewage treatment facility with a processing capacity of 200000 cubic meters per day and related sludge treatment facilities. At the same time, a new sewage east main pipe with a diameter of 1500 to 2200 millimeters will be built, with a total length of about 10.5 kilometers. A new sewage lifting pump station will be built along the line, with a design capacity of 80000 cubic meters per day.
Expansion will serve regional transformation and upgrading. Liu Fahui, the project leader of Jianshe Fangcheng Investment Water Affairs, told reporters that with the transformation and development of the entire Baoshan Wusong area, the scale of sewage treatment in the region is becoming larger and larger. At present, the scale of Wusong sewage treatment plant is 40000 cubic meters per day. With the completion of the second phase expansion project, this newly constructed sewage east main will help to connect the Wusong Sewage Treatment Plant, Taihe Sewage Treatment Plant, and Wusong Innovation City Sewage Treatment Plant under accident and emergency conditions.

Thanks to the application of a new technology, the second phase expansion project can save a lot of time. This morning, the reporter saw at the site of the East Main Pipe Project of Taihe Sewage Treatment Plant that the vertical shaft boring machine with a diameter of 8 meters has been hoisted in place and is ready for deployment.
After the completion of the Taihe 1.2 pipeline project, it will serve as the main sewage collection pipe for the daily sewage treatment plant in the area, serving as a connecting pipe between the Wusong Sewage Treatment Plant, Taihe Sewage Treatment Plant, and Wusong Innovation City Sewage Treatment Plant under accident and emergency conditions.

According to Guan Wei, the project manager of the THK1.2 section of the Shanghai Road and Bridge Taihe Sewage Treatment Plant expansion project of Tunnel Co., Ltd., this technology is called mechanical excavation suspension assembly vertical shaft construction technology. It has the advantages of small footprint, short construction period, high safety and stability, and good environmental control, meeting the land intensive requirements of the construction industry.
After the completion of the second phase expansion project, the total scale of Taihe Sewage Treatment Plant will increase to 600000 cubic meters per day, providing services to nearly 1.5 million people within a 145 square kilometer service area. "After the expansion is completed, Taihe will also enhance the sewage treatment capacity of the Shidongkou area, improve the quality of the regional water environment, ensure the safety of the sewage treatment system, reduce the risk of overflow in the area, and play a comprehensive role in regional pollution interception and control," said Liu Fahui.
