Wastewater/Sewage Discharge Management

Water resources are another issue that Yang Ming gives particular focus. The Company strictly complies with the water resource regulations stipulated by the competent authorities in business locations and the international regulations of the IMO and MARPO in terms of the use of water resources and discharge. 

Water Resource Management Measures

Boundary	Management Measure	Description
Ocean vessels	Ballast water treatment equipment	Refer to 3.7 Biodiversity for details
	Vacuum toilets	The toilets are installed in the accommodation area of vessels to reduce the fresh water consumption for flushing while lowering the volume of water delivered.
	Clean bilge water tanks	The tanks store clean condensation water produced by main engine air coolers to reduce the working load of oil-water separators.
Onshore business locations	Installation of water-saving devices and regular pipeline inspections	Faucets are adjusted to have the proper amount of water flow out each time to avoid wasting water resources. The purchase of products with Water Conservation Marks is prioritized. The pipeline is regularly inspected to see if there is any water leak. RO systems are also used to recycle wastewater.
	Office wastewater management	The domestic wastewater/sewage and rinsing wastewater from the 2nd and higher floors of the building in Cidu are directly discharged to the public sewer of Keelung City, and those from the 1st and lower floors are pumped into the public sewer with the sewage/wastewater pumps in the basement.
Container terminals	Container washing wastewater management	All container washing wastewater is collected in the sedimentation tank, treated with the wastewater treatment system, and then discharged into the sea after meeting the discharge standards of the Bureau of Environmental Protection. The Company reports related water quality inspection results every six months according to laws and undergoes random audits by the Bureau of Environmental Protection.  On average, about 40,000 liters of domestic wastewater/sewage is discharged into the septic tank every month. The Bureau of Environmental Protection is commissioned to pump fertilizers twice every year.
