Shanghai Qingcaosha Reservoir Raw Water Project is a municipal engineering project of the 11th five-year—plan. It consists of three main projects that are reservoir and water intake pump gate, pipeline for raw water of Yangtze River, terrestrial waterlines and pressure pump station. It is a huge urban water supply project. Under the process of design and construction, STEC made impressive achievement to economize on land and water by adopting such innovative technologies as pipeline series booster, pipe jacking curve, anticorrosion steel pipe combination and pipeline series of water hammer. STEC also overcame difficulties during the construction, such as ultra-deep foundation pit, transportation, ventilation and precision measurement of ultra-long distance. The project also managed to cross under tunnels, rivers, houses and maglev which is already in operation. The project won the National Gold Cup for Municipal Engineering Project, the National Gold Medal for Quality Project, the National Customer Satisfaction Project, Shanghai Safe Construction Site, Shanghai Civilized Construction site and Shanghai Environmental-Friendly Construction Site. Shanghai Qingcaosha Reservoir Raw Water Project is a major project to solve Shanghai citizens’ drinking water problems. The water supply area covers 8 districts including Yangpu, Hongkou, Zhabei, Huangpu, Jing’an, Changning, Putuo, and Xuhui, with a scale of 719 cubic meters per day, benefiting 11.5 million people according to the design. After the establishment of the raw water project, the raw water supply system of Shanghai will form a stable pattern of “two parallel rivers and three water sources” by relying on the upstream of Huangpu River, Chenhang reservoir at the mouth of Yangtze River and Qingcaosha raw water supply, thus solving three main difficulties in terms of the total water supply, the quality of drinking water and the safety of water supply in Shanghai.

Project Completion Date:07, 2014
Participating Mode:Design
Project’s Scale:Handle 300 Tons of Sludge Per Day

Shanghai Zhuyuan sludge treatment project, the fourth round of a three-year environmental protection plan and the World Bank loan project, is mainly located within the planning Zhuyuan sludge plant in Waigaoqiao area, Shanghai Pudong New District. It mainly receives and disposes of dewatered sludge from four sludge treatment plants, namely plant one, plant two, Quyang and Sitang in Shanghai Zhuyuan after it was established. It is the largest project with the counterpart technology in Asia Pacific region, and its treatment quantity accounting for a quarter of total sludge amount in Shanghai, and employs the advanced state-of-art “half-dry + incineration” technology. Incineration gas purification employs the technology of “electrostatic precipitator + bag filter +scrubber”, burying the flying ashes into the old harbor after incineration in the short term and utilizing the disposed building materials in the long term, which will guarantee the stability, reduction, reuse and recycle of sludge in Zhuyuan sludge treatment plant after the whole project goes into operation. Shanghai Zhuyuan sludge treatment project solved the difficulty of “sludge around the city”, finding out a way to treat sludge instead of burying it away.

Project’s Scale:Handle 30 Cubic Meters of Sewage Per Day

Shanghai Suzhou Creek Environmental Integrated Improvement Project overcame the difficulty of river closure for dry weather flow in the middle and lower reaches of Suzhou Creek and closed the gaps in the river closure project dealing with direct sewage discharge. The river closure project in the middle and lower reaches involved roughly 10 administrative districts including Jiading, Putuo. The dry weather sewage flow of direct discharge for river closure reaches 30 cubic meters per day. This project is divided into three phases of establishment and improvement of discharge system. The service area of the first phase of the project, tributary sewage for river closure in Suzhou Creek, occupies about 230 square meters, covering 61 discharge system or land parcels. This project effectively controlled and collected sewage produced by the pollution source and decreased the pollution burden that the tributary laid on the mainstream of Suzhou Creek through the large-scale utilization of deodorization techniques in pump stations. The second phase of the project is an important part of water treatment in the latest round of environmental protection plan. The service area occupies 525 square meters. It combined regional planning, built and improved municipal sewage collection system, improved sewage closure facility which offered a path for sewage treatment in rural areas. It built 10 sewage treatment stations, 2 sewage closure facilities, and about 112-kilometer-long rain sewage pipes of which the total investment was 1.08 billion yuan. The third phase of the project covers an area of 525 cubic meters including establishing and improving the discharge system, collecting inland river sewage through drainage pump stations, and rainwater pump station with split-flow rainwater system in charge of river closure for dry weather sewage, involving 20 drainage water systems. It built a 51-kilometer rainwater sewage pipe whose flood and water-logging control capability is 33 cubic meters per second and 3 new closure facilities for dry weather sewage of which the total investment was about 1 billion yuan. The first-stage project won the third prize of National Outstanding Projects in Survey and Design. The second-stage project won the second prize of National Outstanding Projects in Survey and Design. And the third-stage project’s treatment technology won the third prize of Shanghai Scientific and Technological Progress Award in 2007.

After helping to build over 8,300 prefabricated houses in Mianyang city, STEC began to assist Dujiangyan City immediately, supporting the building of two sewage treatment plants in Mount Qingcheng, Dujiangyan City. Dujiangyan Sewage Treatment Plant, located in Mount Qingcheng world cultural heritage site, is the first sewage treatment project in a scenic spot in Chengdu. The project consists of A and B sewage plants, plant A located at the sixth group, Daguan Town in Mount Qingcheng, Dujiangyan City, covering an area of 39.27mu while plant B located at the first group, Puyang town in Dujiangyan city, covering an area of 63.98mu. The project consists of prefabrication, biological treatment structures, affiliated facilities and partial sewage treatment project. On the design of sewage plant, with the professional help of the STEC’s design institute, we chose the best alternative. In terms of the construction, we selected the most talented staff to construct the sewage treatment plant, which became a quality project in the disaster area, and won unanimous compliments. After the establishment of the sewage treatment plant in Mount Qingcheng, its capability of treating sewage was 40,000 tons per day. The sewage after treatment meets the national highest discharge standard: Class A, Level 1, which can not only be used in agricultural irrigation and daily water supply, but also in breeding fish.
