Purchase Mobile Toilet Solution

The plan for purchasing mobile toilets should be comprehensively planned from four aspects: demand positioning, selection criteria, procurement process, and installation, layout, and operation and maintenance management. The details are as follows:

I. Demand Positioning: Match Quantity and Configuration According to Scenarios
Plan the procurement quantity and functional configuration based on the pedestrian flow characteristics of different scenarios:

• Urban Core Business Districts: With an average daily pedestrian flow of over 50,000 people, 2 mobile toilets with 6 female stalls, 4 male stalls, and 1 accessible stall are required.
• Subway Station Exits: With an average daily pedestrian flow of 30,000 people, 3 mobile toilets with 4 female stalls and 3 male stalls are configured.
• Large Parks and Greenways: With an average daily pedestrian flow of 20,000 people, 3 mobile toilets with 3 female stalls, 2 male stalls, and 1 accessible stall are configured.
• Temporary Event Venues: Reserve 2 quickly assemblable and disassemblable simple mobile toilets to cope with sudden surges in pedestrian flow.

II. Selection Criteria: Materials, Functions, and Environmental Protection Must Meet Standards

1. Material Suitability for Scenarios: Steel structure frames with environmentally friendly PVC panels are selected for core business districts and subway station exits, featuring fire and water resistance, corrosion resistance, and a lifespan of over 10 years. For parks and greenways, fiberglass materials are chosen for their lightweight nature and strong weather resistance, facilitating position adjustments.
2. Functional Configuration: All toilets must be equipped with sensor-flush toilets, handwashing stations, hand dryers, activated carbon deodorization systems, and forced ventilation devices. Core business district and park models require additional emergency lighting and accessible handrails. Sewage disposal methods should be adapted to site conditions, with direct discharge for areas with municipal pipelines and 1000L sealed sewage storage tanks with regular pumping services for areas without pipelines.
3. Environmental Protection and Energy Consumption: Products must comply with national environmental protection standards, using water-saving fixtures with a daily water consumption per stall of ≤5L. Park models can be equipped with solar power systems to reduce energy consumption.

III. Procurement Process: Standardized Operations to Ensure Quality

1. Market Research: Screen 3-5 suppliers with ISO9001 quality management system certification and environmental product certification, focusing on their experience in similar projects.
2. Bidding or Inquiry: Clearly define technical parameters, delivery cycles, 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 quality issues).
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 and Maintenance Management: Ensure Long-term Effective Operation

1. Installation and Layout: Toilets in core business districts should be placed on idle land beside the main entrance, within ≤50 meters of the main road and away from fire exits. Subway station toilets should be placed on the sidewalk beside the exit, with non-slip floor treatment. Park toilets should be placed in visitor rest areas or scenic spots.
2. Operation and Maintenance Management: Develop detailed rules for regular equipment inspections, cleaning, and disinfection to ensure the long-term usability of the toilets.
