Changsha Huanghua International Airport

Drinking Water Safety: The drinking water supplied to passengers and airport staff must be ensured to comply with national drinking water hygiene standards. This typically includes regular testing of source water and water within the distribution network, covering microbiological indicators, physicochemical parameters, and other relevant factors.

Wastewater Treatment and Discharge: As a large public facility, an airport generates substantial quantities of domestic sewage as well as industrial wastewater that may contain various pollutants. Such wastewater must be treated to meet prescribed discharge standards before being released into the municipal sewer system or natural water bodies. Consequently, the airport may operate its own wastewater treatment plant, equipped with online monitoring devices to enable real-time tracking of treatment performance and discharge quality.

Stormwater Management: To prevent waterlogging or pollution incidents during heavy rainfall events, the airport is also required to maintain and inspect its drainage system, ensuring that it can effectively remove surface ponding and will not cause environmental pollution due to overflow or other causes.
