New Pumps to Enhance Taipei’s Wastewater Processing Capabilities

Pumping Station is the ‘heart’ of a city’s wastewater treatment system. Spending years moving wastewater, the No. 8 and No. 9 pumps at Dihua Pumping Station have served residents over the past 27 years. First installed in 1995, the performance of these machineries has declined significantly due to wear and tear.


Fully aware of this issue, the Sewerage Systems Office (SSO) made plans to replace these pumps with newer devices. The installation process is slated for completion around April. The new pumps will boost the operating efficiency by roughly 20-percent once they’re in place.


Chief Chang of SSO’s Facilities Management Section pointed out that the primary function of the Dihua Pumping Station is to pump wastewater from the screening area and send it off to either the Dihua Sewerage Treatment Plant or the Bali Sewage Treatment Plant for further treatment. The facility is important in terms of dispatching the effluent to respective destinations.


Each of the replacements has a pumping capacity of roughly 272,160 CMD per day, which is a 20-percent increase compared to past numbers. Furthermore, the new devices are more energy-efficient and will save the city approximately 142,776 kWh each month. This is equivalent to the amount of electricity used by 405 households in a month. 


The agency remarked that it will continue to upgrade related equipment and systems to improve wastewater transport and reduce carbon gas emission. Installation of the devices need to take place outside of rainy seasons and must have minimal impact upon the operation of the pumping station. Fortunately, the careful planning by experts and agency staff and their rich experience in executing constructions help ensure the pumps can be replaced according to schedule.
