Review of Mobile Toilets in Nanjing

Mobile toilets in Nanjing are a common solution for temporary restroom needs, and their selection should be based on a comprehensive consideration of usage scenarios, type characteristics, rental services, and special requirements.

I. Selection Based on Usage Scenarios and Core Requirements

1. Event Type and Scale: For large-scale festivals and sports events, it is advisable to prioritize flush-type models or those with large-capacity storage tanks to ensure efficient turnover during peak periods. For scattered locations such as construction sites and parks, durable packing-type or biodegradable models are recommended.
2. Duration and Frequency of Use: For short-term events (1-2 days), simple packing-type toilets can be selected, while long-term use (such as at construction sites) requires sturdy, well-equipped flush-type or biodegradable models.
3. User Population: Public areas should be equipped with barrier-free toilets (with wide entrances and handrails), while temporary home use (such as during renovations) can focus on privacy and convenience.
4. Installation Environment: A flat and hard surface (such as concrete or stone pavement) is required, and muddy or grassy areas need reinforcement. Nearby access to electricity or water is necessary, and flush-type toilets require regular emptying of storage tanks.

II. Understanding the Characteristics of Mobile Toilet Types

1. Packing-Type: These do not require external water or electricity connections. They use mechanical devices to pack waste into degradable bags, offering low costs and flexible placement, but requiring regular replacement of consumables.
2. Flush-Type: These provide an experience similar to traditional toilets and come in two types: those connected to an external water pipe and those with their own clean water tank. They require regular emptying of the fecal storage tank and are suitable for scenarios with high hygiene requirements.
3. Biodegradable-Type: These utilize microorganisms or chemical agents to decompose waste, reducing odors and the frequency of emptying. They are environmentally friendly but have higher costs.
4. Waterless-Type: These use foam sealing or vacuum suction technology, consuming minimal water and being suitable for water-scarce environments.

III. Key Points of Rental Services and Processes

1. Service Provider Selection: Local service providers in Nanjing include Yunshui Environmental Protection and Jiedu Environmental Protection, while national chain enterprises such as Shanghai Xinzhang Environmental Protection cover all districts of the city.
2. Price Range: Basic models cost 200-500 yuan per day, while luxury models with more complete facilities are priced higher.
3. Rental Process:
   • Clarify Requirements: Allocate one toilet per 100-150 people, determine the usage time, equipment type (such as standard or barrier-free), and site conditions (flat ground, proximity to water sources).
   • Contact Service Providers: Obtain information through commercial platforms or referrals and initially communicate requirements.
   • Confirm the Plan: Review the cost breakdown (including transportation, installation, and cleaning and maintenance fees) to avoid hidden charges.

IV. Special Requirements and Precautions

• Barrier-Free Design: Prioritize models with an entrance width of ≥90 cm and handrails.
• Large-Scale Event Reservations: Reserve one to two toilets per 100 people, 3-7 days in advance, and even earlier during peak seasons.
• Customized Services: For example, Nanjing Haojia offers double-unit home mobile restrooms with fine decoration features such as plastic-wood flooring, aluminum alloy doors, and ceramic washbasins.
