Shanghai Mobile Toilet Solution

Shanghai's mobile toilet solution has evolved from an emergency facility to a refined urban infrastructure project, covering the entire process of site selection, technology, design, and operation and maintenance, reflecting the integration of humanization and intelligence.

Site Selection Strategy: Data-Driven Hierarchical Distribution The site selection for Shanghai's mobile toilets is based on data such as pedestrian heat maps, large-scale event plans, and temporary needs in old residential areas, adopting a hierarchical distribution model. Through the flexible deployment method of 'plug and play', it fills the coverage blind spots of fixed public toilets while adhering to two major principles: not interfering with the landscape of main roads to ensure harmony with the urban appearance, and being within a 5-minute walk to enhance convenience. For example, denser distribution is implemented in high-traffic areas such as business districts and transportation hubs, while temporary sites are set up around old residential areas to meet sudden demands.

Technological Innovation: Emphasis on Environmental Protection and Intelligence Technologically, Shanghai's mobile toilets adopt two core solutions:

1. Microbial Degradation Technology: By using microorganisms to decompose waste, internal circulation is achieved, eliminating dependence on municipal sewer networks and suitable for areas without sewers.
2. Packaging + Vacuum Suction Combination: This reduces the frequency of waste removal and lowers operation and maintenance costs. Additionally, intelligent components are equipped, such as electronic screens displaying 'occupied/unoccupied' status in real-time and automatic deodorization spray systems, enhancing the user experience. Some toilets also integrate mobile phone charging ports to meet modern living needs.

Design Details: Age-Friendly and Function Expansion The design focuses on age-inclusiveness and barrier-free facilities:

• For the elderly, children, and mothers with infants, safety features such as one-touch emergency buttons and anti-collision rounded corners are installed.
• At least 15% of the toilet stalls are designated as third toilets or barrier-free stalls to meet the needs of special groups.
• Ventilation adopts an 'upper supply, lower exhaust' model to optimize air circulation.
• The appearance is gradually evolving towards a public toilet and modular design, with some solutions integrating facilities such as refrigerators and shower rooms. For example, seven upgraded mobile public toilets on Haitong Road and Meihua Road in Pudong New Area have added barrier-free access and 'sanitation stations', reflecting a human touch.

Operation and Maintenance System: Dynamic Response and Departmental Collaboration In terms of operation and maintenance, a dynamic management mechanism is established:

• Increasing the frequency of waste removal and cleaning during peak hours to ensure hygiene standards.
• Pre-setting reinforcement measures for extreme weather to safeguard facility safety.
• Establishing a collaborative process with local sanitation and urban management departments to achieve rapid response and resource allocation. This system ensures the efficient operation of mobile toilets throughout their entire lifecycle, from construction to use.
