Mobile Toilet Recommendation

Mobile toilets are designed as fully movable facilities to meet temporary or phased toilet needs, suitable for various locations and characterized by flexibility, environmental friendliness, and cost-effectiveness.

I. Suitable Locations and Structural Materials Mobile toilets are suitable for areas with dense populations or difficulties in constructing fixed public toilets, such as stations, docks, tourist attractions, construction sites, and squares. Their structures typically include fecal storage tanks, sanitary fixtures, walls, roofs, and moving devices. The materials have evolved from early wood to lightweight corrosion-resistant materials like fiberglass and polyethylene, with some using lightweight stainless aluminum steel to reduce energy consumption and operating costs.

II. Classification and Sewage Treatment Methods They are classified by structural form into single and composite structures; by moving method into hoisting and powered towing types; and by sewage treatment method into water-flush, waterless suction, recirculating water-flush, and dry-packing types. For example, the dry-packing type requires no water source and is suitable for water-scarce areas; the recirculating water-flush type achieves water reuse through biodegradation technology, highlighting its environmental friendliness.

III. Allocation Principles and Scenario Applications

1. Small Events (under 100 people): Allocate 1-2 toilets per 50 people, such as 1 single-person toilet for under 50 people, and 2 single-person or 1 two-person toilet for 50-100 people, with 1 spare reserved.
2. Medium Events (100-500 people): Allocate 2-3 toilets per 100 people, with a recommended male-to-female ratio of 1:1.5. For example, for a 200-person event, 2 two-person and 1 single-person toilet are recommended; for over 300 people, 4-5 toilets are needed, with accessible toilets added.
3. Large Events (over 500 people): Allocate 3-5 toilets per 100 people, such as for a 1000-person event, 3 two-person, 3 single-person, and 1 accessible toilet are suggested, with temporary handwashing stations added during peak times.
4. Special Scenarios: For long-term use scenarios like construction sites and scenic spots, allocate 1 toilet per 30-50 people; for campsites, 1 per 20 people is recommended, paired with shower rooms, and a 10% spare reserve is suggested to cope with equipment failures or sudden increases in numbers.

IV. Design Principles and Functions Design should adhere to principles of mobility, cost-effectiveness, durability, and environmental friendliness, using lightweight and durable materials, controlling height and width, and ensuring complete moving devices. Their origin aims to compensate for the insufficient number and layout defects of fixed public toilets, playing a crucial role especially in difficult urban construction areas, while promoting social sustainable development through resource conservation and pollution reduction.
