Five-A Level Mobile Toilet Standard
The Five-A Level Mobile Toilet Standard covers five dimensions: site selection and layout, functional design, environmental protection technology, management services, and cultural and smart management. The specific requirements are as follows:
I. Site Selection and Layout Planning
Site selection should balance visitor convenience and landscape harmony. One toilet should be placed every 500-800 meters along major sightseeing routes, and the distance can be shortened to 300-500 meters in high-traffic areas (such as entrances and scenic spot intersections). The toilet layout should avoid the main view of the landscape and adopt a semi-concealed design (e.g., using greenery or terrain for blocking). It should also be close to rest areas but maintain a distance of 10-15 meters to avoid odor interference. The passage width should be ≥1.2 meters, the slope ≤1:12, and it should be equipped with night lighting (illuminance ≥30 lux) and non-slip floors to ensure barrier-free and safe passage.
II. Modular Functional Design
The basic functional areas should be configured differently according to gender: men's toilets should have squat toilets and urinals (ratio 1:3), and women's toilets should have squat toilets and sit toilets (ratio 1:1), and be equipped with barrier-free toilets (including handrails, emergency call buttons, and low-level washbasins). Smart upgrade options include sensor-based flushing systems (water-saving rate ≥40%), smart ventilation systems (automatically adjusting air speed according to foot traffic), and remaining stall displays. Special scenario configurations include baby care rooms (with baby changing tables, bottle warmers, and independent air conditioning), emergency power supplies (supporting 8 hours of power), and epidemic prevention facilities (non-contact hand sanitizer dispensers and ultraviolet disinfection lamps).
III. Integrated Environmental Protection Technology
The ecological treatment system uses microbial degradation technology with a treatment efficiency ≥90% and no secondary pollution; solar power generation for a single toilet should be ≥5kWh per day, meeting basic power needs. Water-saving solutions include waterless urinals (saving about 100 tons of water per toilet per year) and low-flow flushing systems (≤4L per flush for sit toilets and ≤2L per flush for urinals). In terms of material selection, the main structure should use galvanized steel plates or fiberglass (corrosion resistance grade ≥A), with surface treatments such as fluorocarbon spraying (weather resistance ≥15 years) or imitation stone veneers (to match the scenic spot style).
IV. Management Service Requirements
One cleaner should be assigned for every 2-3 toilets, with a friendly service attitude and a visitor satisfaction rate ≥90%. The cleaning standard is at least three times a day, with inspections every two hours during peak times, using neutral detergents (pH value 6-8) to avoid corroding materials. In terms of consumables management, there should be ≥2 rolls of toilet paper per squat toilet, ≥500ml of hand sanitizer per sink; garbage bags should be replaced every two hours during peak times and every four hours during off-peak times.
V. Cultural Atmosphere and Smart Management
The interior decoration of the toilets should be integrated with the cultural theme of the scenic spot, and a cultural display area should be set up, with content updated at least once every quarter. Smart management includes a visitor flow monitoring system (real-time display of toilet stall status), environmental sensors (automatically adjusting ventilation and deodorization equipment), and a 'one toilet, one code' evaluation system (visitors scan the code to provide feedback on satisfaction).
