Illustrated Guide to Mobile Toilet Layout Specifications

There is currently no direct illustrated guide to mobile toilet layout specifications in the Fuzhou area, but designs can be created by combining written specifications with on-site conditions. Below are the key layout requirements:

I. Spacing and Quantity of Toilet Points

1. Large Events: Allocate one toilet stall for every 50-100 people, with a maximum spacing of 100 meters between stalls. For example, a music festival with 10,000 attendees would require 25 toilet stalls, spaced within 80 meters.
2. Small Temporary Areas: Provide one mobile toilet for every 200 square meters, such as in markets or temporary construction sites.
3. Gender Ratio of Toilet Stalls: For large events, a ratio of 1:1.5 (male to female) is recommended, while a 1:1 ratio can be used in general scenarios to reduce female waiting times.

II. Facility Configuration Standards

1. Internal Design:
   • Odor Control System: Utilize water seals or biodegradation technology, with water-flush toilets using no more than 3 liters per flush.
   • Safety Features: Install non-slip floor tiles, handrails beside squatting stalls, and ensure accessible toilet stalls are at least 90 centimeters wide.
   • Cleaning Requirements: Dry toilets must be cleared every 24 hours, while water-flush toilets should be disinfected twice daily.
2. External Signage:
   • Display bilingual (Chinese and English) signs for 'Male' and 'Female', and install reflective strips or LED light strips at night.
   • A common configuration is 'three squatting stalls + one accessible stall', with directional arrow signs at the entrance.

III. Site Selection and Environmental Adaptation

1. Terrain Requirements: Avoid low-lying flood-prone areas, strong wind zones, and drinking water sources, maintaining a minimum distance of 5 meters from dining areas.
2. Ground Treatment: Choose hardened ground in construction areas and secure toilets with expansion bolts; in outdoor scenic spots, toilets can be concealed among trees or flowers but must be laid with non-slip floor tiles.
3. Isolation Measures: Install fences or green belts around the toilets to maintain visual separation from the main event area and reduce odor impact.

IV. Circulation and Supporting Facilities

1. Pedestrian Flow Guidance: Use continuous arrow signs to connect the main entrance with the toilet area, avoiding cross-traffic congestion.
2. Handwashing Station Setup: Install additional mobile handwashing stations near dining areas, keeping them at least 10 meters away from the toilet area to prevent water splatter.
3. Emergency Equipment: Equip each toilet stall with a trash bin, lighting, and an emergency call button. Install cooling fans in hot weather and heating facilities in cold regions.

V. Hygiene Management and Maintenance

1. Daily Inspections: Check the water and electricity systems, flushing equipment, and consumables (such as toilet paper and disinfectant) daily.
2. Clearance Timeliness: Complete fecal clearance and toilet reset within 4 hours after the event ends to prevent bacterial growth.
3. Disinfection Process: Use chlorine-based disinfectants to spray the interior and exterior of toilet stalls, focusing on high-contact areas such as door handles and flush buttons.
