166 Mobile Toilet

In the context of mobile toilets, '166' primarily refers to the ratio standard of providing at least 3 mobile toilets for every 500 participants (1:166), which is commonly seen in the leasing regulations of large-scale events such as the Nanyang Marathon.

1. Specific Meaning of the '166' Ratio

In large-scale events like the Nanyang Marathon, the deployment of mobile toilets should adhere to the '1:166' ratio standard, meaning that one mobile toilet should be provided for every 166 participants. For example, for 500 participants, at least 3 mobile toilets should be provided (500÷166≈3). This ratio aims to balance usage demand with resource costs, avoiding queue congestion due to insufficient toilets or resource waste due to excessive deployment.

2. Customization Options for Mobile Toilets

In addition to standard configurations, some mobile toilet products support customization according to demand, subject to the merchant's offerings. Common customization dimensions include:

• Brand and Type: Brands such as Jindongfang and Boyi Metal offer types like mobile toilets and container toilets, with the former being highly flexible and the latter suitable for long-term fixed use;
• Material and Workmanship: Materials include color-coated steel and steel structures, with workmanship such as welding. The choice should be based on the usage scenario (e.g., outdoor, temporary, or long-term) to select a durability-matched solution;
• Sewage Disposal Method: Vacuum self-priming types are suitable for water-scarce environments, while water-flush types require a water connection. The choice should be based on site conditions.

3. Applicable Scenarios and Significance of the '166' Ratio

This ratio is primarily applied to the temporary toilet deployment in large-scale events (e.g., marathons, music festivals), with its core significance lying in:

• Scientific Planning: Avoiding blind resource allocation through quantified standards to ensure the basic needs of participants or spectators;
• Cost Control: Reducing unnecessary toilet numbers to lower leasing, transportation, and maintenance costs while meeting demand;
• Flexibility: The ratio can be adjusted according to event scale (e.g., increasing deployment proportionally as participant numbers rise) to suit different scenarios.

For further optimization of mobile toilet deployment, it is recommended to conduct a comprehensive assessment considering factors such as event duration, gender ratio (higher demand for female toilets is common), and site layout to ensure service efficiency and user experience.
