Night Market Mobile Public Toilets

Night market mobile public toilets are temporary or movable public sanitation facilities designed to address the high demand for restroom services in night markets with large crowds, aiming to alleviate the issue of 'difficulty in finding restrooms' caused by the insufficient number of fixed public toilets.

Typical Cases and Demand Pain Points

1. Prominent Supply-Demand Imbalance
   For example, Lincheng Night Market has only one mobile toilet (with two squatting positions), which is far from sufficient to meet the demand during peak hours, leading to frequent incidents of public urination and defecation. Longsheng Night Market on Jiefang Road lacks public toilets altogether, forcing diners and vendors to relieve themselves in green belts and other areas, severely polluting the environment and affecting the city's appearance. These cases indicate that night market areas often suffer from low coverage of fixed public toilets due to site constraints or delayed planning, making mobile toilets a crucial supplementary facility.

2. Demand for Public Service Upgrades
   Jingdezhen's Jingtai Road Night Market invested 800,000 yuan to build a new fixed public toilet (including five male positions, eight female positions, and barrier-free facilities), not only solving the problem of no supporting public toilets in the surrounding area but also enhancing the inclusiveness of public services through barrier-free design. Such practices demonstrate that the coordinated layout of mobile and fixed public toilets is an important direction for optimizing the night market environment.

Technical Classification and Core Advantages

1. Structural Forms
   They are divided into single-unit structures (independent units) and composite structures (multi-unit combinations), allowing flexible capacity adjustments based on the size of the night market. For example, small night markets can adopt single-unit structures for rapid deployment, while large night markets can achieve efficient coverage through composite structures.

2. Mobility Methods
   These include lifting-type (requiring lifting equipment), handling-type (by manual or small machinery), powered-type (with built-in drive systems), and towed-type (tractable by vehicles). Powered and towed types are suitable for night markets that require frequent relocation, while lifting-type is more appropriate for long-term fixed locations.

3. Sewage Treatment Methods

• Flush-type: Relies on municipal water supply, offering high cleanliness but requiring supporting sewage pipes;
• Waterless suction-type: Uses vacuum pumps to suction feces, suitable for water-scarce areas;
• Recirculating flush-type: Utilizes biodegradation technology to purify sewage, enabling water resource recycling;
• Dry packing-type: Uses biodegradable bags to collect feces, requiring no water or electricity, suitable for remote or temporary night markets.
  Advantages: Their mobility allows for rapid response to demand changes, their combinability supports dynamic capacity adjustments, their transport convenience reduces deployment costs, and they effectively compensate for blind spots in the layout of fixed public toilets.

Design Principles and Policy Support

1. Design Principles
   Emphasis is placed on mobility (lightweight materials, modular structures), economic durability (corrosion and rust resistance treatment), environmental protection and ecology (water and energy-saving technologies), and improved efficiency (reasonable ratio of male to female toilet positions). For example, the configuration of barrier-free facilities must comply with the requirements of the 'Urban Public Toilet Design Standard' (CJJ 14-2016).

2. Policy Initiatives
   The Jingdezhen City Administration Bureau has included mobile toilets in its livelihood projects, implementing the requirements of the government work report through the construction (renovation) of public toilets, reflecting the importance attached to the night market environment by public policies. Such measures provide a replicable governance model for other cities.
