This pumping station has been set up for a long time. In order to improve the overall function, this project will update the motor starter inverter and increase the voltage level to 3300 volts. The original pump is also updated, at the same time, to solve the load saturation and malfunction problems of the downstream Lion Head Pumping Station, the pumping unit was upgraded to 1700 KW. In case of emergency demand, the new overflow pressure line can be discharged to the Tamsui River. After the completion of the project, in addition to enhancing the function of the Xinzhuang pumping station, it can also ensure the safety of the equipment in the station and avoid being submerged by heavy rain.

The sewage sewerage system of Taipei City has completed 6 (100%) of the main trunks and 27 (97.55%) of the secondary trunks, and the user acceptance rate has reached 75.21%. The Dazhi and Neihu main trunk systems are discharged into Neihu Wastewater Treatment Plant, the remaining main pipe system is discharged into the Dihua sewage pumping station, and then lifted and transported to the Dihua sewage treatment plant. During the heavy rain in recent years, the amount of rainwater has become triple and resulted in insufficient pumping energy for the existing Dihua sewage pumping station.Engineering Features:
▲ Difficulties: New and old channels are connected. In order to avoid the loss of bacteria in the biological reaction tank of the sewage treatment plant and affect the water quality of sewage treatment, it is necessary to complete the restoration of water supply within the shortest time. The construction company manual construction day and night to demolish existing channels, on-site cutting of stainless steel formwork, assembly of formwork and support system steel banding and concrete casting, in order to achieve the goal.
▲ Exceeding the cost of the equipment factory inspection: In order to ensure the quality of the project, before the factory produce the pumping machine, the motor and the operating disc are transported to the qualified (TAF) laboratory. The laboratory's circulating water channel was used after the false assembly. Then, the performance test of the pumping curve was carried out. A total of 48 hours were tested separately and in parallel.
▲ Using water storage to test: From the completion of the installation to the deadline of the project, it is impossible to predict whether there is water to handle the function test of the pumping unit. The organizer has reviewed the intake valve of the existing Dihua sewage pumping station after detailed review. Water is stored in the pipeline system, and diverted it to the wet
well of the pumping station for on-load test. By doing so, we can ensure that the overall system function meets the demand.
▲ Environmental Conservation: Plants should be properly transplanted in the work area, and green beautification and grass-planting bricks should be included for the ecological sustainability.
