On 4th June, 2015, PWT construction project, the largest and most advanced underground pumping station in Hangzhou - Hemugang pump station was successfully operated. The station is capable of 78 tons per day. In the future, about 50% wastewater of Hangzhou will transferred to this station and delivered to Qige WWT Plant for purification. The operation the project made an important breakthrough in the EPC field.

Background

On 10th May, Sibao WWT Plant was officially closed, the original water which entered the plant was transferred to Qige WWT plant, and the pipeline between these two plants is 9.8 kilometers.

As we know, total investment of Hemugang WWT Plant is 88,857,500 RMB, covers an area of 26,750 square meters, and the greening rate is more than 70%, which is the largest and most advanced underground pumping station in Hangzhou. Wastewater transfusion volume is up to 780,000 t/d. After put into operation, transfusion can rely on the "gravity flow run" to enhance the operational safety of pipes, and greatly enhance the capability of water transfer. Moreover, the station will in charge of the purification of High School campus along the Qiantang River.

Advantages

Hemugang WWT Plant is an underground pumping station, major equipment are built underground, and therefore produce little noise when running. When wastewater arrives here, it will go through a simple filtration, larger garbage will be blocked and pulverized, and then flows into the sewers; pump station has biological, ions, chemical three deodorizing device, ensure that the sewage generated in transfusion the exhaust gas in time, to meet national standards before discharge; in addition, also on the sewage pumping station water quality monitoring, water quality exceeded once found, will automatically send an alert to notify downstream of sewage treatment plants and environmental protection sectors.
