Guangzhou Metro Portable Toilet
Guangzhou Metro's portable toilets exhibit significant features and achievements in procurement, application, technological innovation, and maintenance management.
Procurement: Guangzhou Metro Group Co., Ltd. once conducted a domestic online price comparison for the procurement project of fixed assets for portable toilets and related services for the Guangfo Line in 2024. The owner of the materials is Guangdong Guangfo Rail Transit Co., Ltd. After winning the bid, the winning bidder is required to sign a contract with the owner, reflecting Guangzhou Metro's standardized procurement process for portable toilets.
Diverse Application Scenarios: In the Tianhe CBD area, movable portable toilets are placed near subway entrances and commercial districts with heavy foot traffic. They are open 24 hours a day and maintained by dedicated personnel. In the pilot area, complaints about public urination have decreased by 67%, and citizen satisfaction has significantly improved. During large-scale exhibitions and sports events, such as the Canton Fair, more than 500 portable toilet units were deployed at once around the Pazhou Exhibition Hall, effectively alleviating the toilet pressure for exhibitors and visitors. Additionally, two portable public toilets have been put into use at Exit C and Exit D of Panyu Square Subway Station, each with four toilet stalls. Outside the stalls, there are sinks and faucets. Inside the toilets, there is free toilet paper, and sewage pipes are installed to discharge waste into underground septic tanks.
Outstanding Technological Innovation: The third-generation portable toilets used in Guangzhou are equipped with multiple intelligent functions, such as sensor-based flushing, automatic disinfection, and emergency call buttons. Some toilets are also installed with solar panels to achieve self-sufficiency in energy. The interior space is carefully designed to ensure barrier-free access for the disabled, enhancing the user experience and convenience.
Comprehensive Maintenance Management: The Guangzhou municipal department has established a dedicated cleaning and maintenance team for portable toilets, which conducts inspections every 2 hours to ensure that hygiene standards are met. Each toilet is equipped with a QR code, allowing citizens to evaluate hygiene conditions or report repairs by scanning the code. The management department can monitor the situation at each location in real-time, ensuring the normal use and hygiene of the portable toilets.
