Mobile Toilet Purchase Plan

The purchase of mobile toilets should be based on demand positioning, selection criteria, procurement processes, and installation and operation management. The specific plan is as follows:

I. Clarify Demand Positioning
Plan the procurement quantity and configuration according to the pedestrian flow characteristics of different scenarios:

• Urban Core Business Districts: With an average daily pedestrian flow exceeding 50,000, two mobile toilets with 6 female toilet stalls, 4 male toilet stalls, and 1 accessible toilet stall are required to meet peak-hour demand.
• Subway Station Exits: With an average daily pedestrian flow of 30,000, three mobile toilets with 4 female toilet stalls and 3 male toilet stalls are configured to accommodate both commuting and transient populations.
• Large Parks and Greenways: With an average daily pedestrian flow of 20,000, three mobile toilets with 3 female toilet stalls, 2 male toilet stalls, and 1 accessible toilet stall are configured to adapt to the dispersed distribution of visitors.
• Temporary Event Venues: Reserve two easily disassembled and assembled simple mobile toilets to cope with sudden surges in pedestrian flow and ensure flexibility.

II. Establish Selection Criteria

1. Material Selection:
   • For core business districts and subway station exits, choose steel frame structures with eco-friendly PVC panels, which are fire-resistant, waterproof, and corrosion-resistant, with a lifespan exceeding 10 years.
   • For parks and greenways, select fiberglass materials, which are lightweight for easy mobility and have strong weather resistance.
2. Functional Configuration:
   • Basic configurations: Sensor-flush toilets, handwashing stations, hand dryers, activated carbon deodorization systems, and forced ventilation devices.
   • For core business districts and park models, add emergency lighting systems and accessible handrails to enhance safety and convenience.
3. Sewage Disposal Methods:
   • In areas with municipal sewage pipelines, use direct discharge methods; in areas without pipelines, select 1000L sealed sewage storage tanks paired with regular pumping services.
4. Environmental Protection and Water Conservation:
   • Comply with national environmental protection standards, use water-saving fixtures, with an average daily water consumption per toilet stall of ≤5L.
   • Park models can be equipped with solar power systems to reduce energy consumption.

III. Standardize Procurement Processes

1. Market Research: Screen 3-5 suppliers with ISO9001 quality management system certification and environmental product certification, focusing on their experience in similar projects (such as urban events or business district supplies).
2. Bidding or Inquiry: Clearly define technical parameters, delivery schedules, and after-sales service requirements, and request suppliers to provide product samples and test reports.
3. Contract Signing: Agree on a warranty period of ≥2 years, a maintenance response time of ≤24 hours, and set penalty clauses (a penalty of 5% of the contract amount for late delivery or substandard quality).
4. On-site Acceptance: Jointly inspect the appearance and functional accessories with municipal and environmental protection departments, conduct a 72-hour trial run, and complete acceptance after confirming no issues such as water leakage or deodorization failure.

IV. Installation Layout and Operation Management

1. Installation Layout:
   • Core business districts: Place on idle land beside the main entrance, ≤50 meters from the main road, avoiding fire exits.
   • Subway station exits: Place on the sidewalk beside the exit, with anti-slip ground treatment.
   • Parks: Place near visitor rest areas or scenic spots.
2. Operation Management: Develop detailed rules, including regular cleaning, equipment maintenance, and sewage tank pumping, to ensure long-term effective operation.
