Mobile Toilet Construction Standards

Currently, there are no unified and independent construction standards specifically for mobile toilets, but construction considerations can be made by combining their classifications and relevant general standards. Details are as follows:

From the perspective of the classification characteristics of mobile toilets themselves:

• By structure: Monolithic mobile toilets are relatively independent. During construction, it is necessary to ensure their structural stability so that they can withstand certain external forces, such as bumps during transportation and human activities during use. Composite mobile toilets are composed of multiple parts, and the connections between these parts should be tight and reliable to ensure the integrity and stability of the overall structure.
• By mobility method: For mobile toilets that are lifted and transported, the setting of lifting points needs to be considered to ensure that the entire toilet is evenly stressed during the lifting process and that no local damage occurs. For mobile toilets that are towed by power, attention should be paid to the quality and performance of the towing device to ensure safety and reliability during towing and driving, and to prevent dangerous situations such as detachment.
• By sewage treatment method: For waterless packing mobile toilets, attention should be paid to the sealing of the packing device to prevent fecal leakage and environmental pollution. For mobile toilets with water flushing functions, such as ordinary water-flushing and water-saving flushing types, it is necessary to ensure that the water tank has a stable capacity and water pressure, and at the same time, the sewage treatment system should be able to effectively treat sewage to prevent sewage overflow. For microbial degradation mobile toilets, it is necessary to ensure the activity and degradation effect of the microorganisms and regularly maintain and supplement them.

From the perspective of general standards: Although the revised draft for comments of the Urban Public Toilet Design Standard (CJJ14 - 2016) does not explicitly involve specific clauses for mobile toilets, some of its concepts can be used for reference. For example, in terms of hygiene, it is necessary to ensure that the interior of the mobile toilet is clean and hygienic, well-ventilated, and reduces odor generation; in terms of safety, necessary protective facilities such as non-slip floors and handrails should be installed to ensure the safety of users.
