Mobile Toilet Water Tank Capacity Selection

The selection of the water tank capacity for mobile toilets should be comprehensively determined based on the usage scenario, usage frequency, maintenance cycle, climatic conditions, and special requirements. Specific recommendations are as follows:

I. Basic Capacity Range

1. General-purpose water-storage mobile toilets: Suitable for outdoor scenarios without sewer facilities (such as parks and scenic spots), the water tank capacity is usually 100-300 liters, and the sewage tank needs to be cleaned regularly.
2. Mobile toilet sewage tanks: The basic capacity range is 200-500 liters. Among them, small and simple models (such as those temporarily used on construction sites) are equipped with 200-300-liter water tanks; large-scale events (such as music festivals) require large-capacity water tanks of over 400 liters.

II. Key Influencing Factors

1. Usage frequency: The water tank capacity needs to match the average daily number of users. For example, a toilet used by 50 people per day needs to have a capacity 30% larger than that used by 20 people per day to avoid frequent cleaning.
2. Maintenance cycle: If the cleaning cycle is 3 days, the water tank capacity needs to be twice as large as the specification for daily cleaning; if cleaned daily, a smaller capacity can be selected.
3. Climatic conditions: In hot areas, due to high evaporation and rapid odor diffusion, a 20% capacity margin should be reserved to ensure user comfort.
4. Special requirements: For models dedicated to the disabled, due to the larger amount of water used for each flush, the water tank capacity needs to be increased by an additional 15%; if equipped with water-saving devices (such as vacuum suction types), the capacity can be appropriately reduced.

III. Typical Scenario References

1. Small-scale events or construction sites: Choose a 200-300-liter water tank to meet the needs of less than 50 people per day, with a maintenance cycle of 1-2 days.
2. Large-scale events or scenic spots: Equip with a water tank of over 400 liters to support the use by 200 people per day (for example, a mobile toilet with a built-in 400-liter wastewater tank can serve about 200 people). After the tank is full, it needs to be pumped and treated by professional vehicles.
3. Long-term fixed usage scenarios: Prioritize the selection of water-storage (with a sewage tank) equipment, and adjust the capacity according to the actual usage frequency and maintenance capabilities to avoid sewage overflow due to insufficient capacity.

Summary: The selection of the water tank capacity should take actual needs as the core, and be comprehensively evaluated in combination with the usage scenario, maintenance conditions, and climatic factors to ensure the efficient operation of the equipment and controllable maintenance costs.
