How to Set Up Mobile Toilets for Street Vendors

Setting up mobile toilets for street vendors involves following processes such as preliminary planning, layout, installation, management, and compliance. Here are the specific steps:

I. Preliminary Planning

1. Determine Usage Scale: Configure toilet stalls based on the number of attendees and event duration, with 1 mobile toilet required for every 50-80 people. For example, an event with 1,000 people requires at least 13 toilet stalls, including accessible and baby-changing stalls.
2. Site Inspection: Check ground load-bearing capacity (≥2 tons/㎡), spatial dimensions, and avoid low-lying areas prone to water accumulation. Confirm electricity and sewage conditions, as some models require external power sources.

II. Layout Principles

1. Location Selection:
   • Close to pedestrian routes, within ≤100 meters of the main area, and maintain a distance of over 15 meters from dining areas and restrooms.
   • Convenient transportation, within ≤50 meters of the main venue or entrance, avoiding muddy or steep sections.
   • Privacy: Keep away from crowded areas (e.g., stages), maintain a distance of ≥2 meters from temporary structures, and avoid facing entrances or exits directly.
   • Choose a location higher than the surrounding ground to ensure the sewage pipe of the septic tank connects to the municipal sewer system or set up temporary drainage facilities.
2. Zoning Setup:
   • The recommended ratio of regular male and female toilets is 1:1, with 1-2 additional stalls added during peak female usage times.
   • Set up special needs areas (accessible, baby-changing) separately with clear signage.
   • Configure toilet stalls at a ratio of 1:20 based on the estimated number of people, adding 1 accessible stall for every 50 people during peak female usage times.
   • Ensure aisles between adjacent stalls are ≥1.5 meters wide to accommodate wheelchair passage, and doors do not obstruct adjacent facilities when opened.

III. Construction and Installation

1. Foundation Treatment: Use cement hardening or lay anti-slip mats, reserving ≥60 cm of operating space around the equipment. Temporary toilets require concrete bases for fixation, with a load-bearing capacity of ≥5 tons/㎡.
2. Sewage Disposal Plan:
   • Models with sewage tanks require planning for waste removal routes, prioritizing connection to the municipal sewage system.
   • Septic tanks should be cleaned every 3 days, with wastewater meeting the 'Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants' and prohibited from being discharged into storm drains.
3. Supporting Facilities: Install clear signage (visible from 50 meters away), equip with lighting systems (brightness ≥30 lux at night), and lay anti-slip tiles or mats on the ground.

IV. Post-Installation Management

1. Daily Inspections: Check equipment status every 2 hours, clear garbage, and replenish toilet paper and hand soap.
2. Emergency Plan: Reserve 1-2 spare units, prepare disinfectants and repair tools; inspect drainage holes during the rainy season and add insulation layers during winter to prevent freezing and cracking.

V. Compliance Requirements

1. Filing: Submit a 'Temporary Facility Filing Form' to the sanitation department and display the filing number publicly.
2. Environmental Protection: Prohibit setup in green belts or ancient tree protection areas, classify and remove garbage; equipment must comply with the 'Standard for the Setup of Urban Environmental Sanitation Facilities' and provide testing reports; leasing units must possess environmental protection filing qualifications.

VI. Leasing Service Standards

Choose a reputable company, requiring site surveys 72 hours in advance, completion of installation and commissioning within 3 days, and daily inspections by an operation and maintenance team; the contract must specify emergency plans (e.g., handling rainstorms and equipment failures).
