Outdoor Mobile Double-Squat Toilet Installation

The installation of outdoor mobile double-squat toilets requires scientific planning and standardized operations. The key steps and precautions are as follows:

I. Planning and Site Selection Before Installation

1. Site Condition Assessment
   Choose a flat and solid ground, avoiding low-lying areas, slopes, or soft soil regions to prevent toilet tilting or damage due to unstable foundations. If the site is slightly uneven, adjustments can be made using pads or gravel filling.

2. Location Convenience and Environmental Impact
   The site should be close to main activity areas or pedestrian paths while maintaining a minimum distance of 10 meters from dining areas and water sources to avoid contamination risks. Consider the prevailing wind direction throughout the year and place the toilet downwind of residential or activity areas to minimize odor dispersion affecting people.

3. Quantity and Layout Planning
   Scientifically estimate the required number of toilets based on foot traffic, event duration, and gender ratios. For example, large events can follow the standard of one squat position per 50-100 people. When arranging multiple units, maintain an orderly layout with a spacing of 1.5-2 meters for ventilation and ease of use.

II. Technical Points During Installation

1. Foundation Treatment and Fixation

   • Short-term Use: Use sturdy pads or lay a 5-10 cm thick gravel layer to distribute pressure and increase stability.
   • Medium to Long-term Placement: Pour a simple concrete foundation (thickness ≥ 15 cm) or use dedicated ground anchor fixation devices to ensure wind resistance.

2. Level Adjustment and Stability
   Use a level to calibrate the toilet's position. Adjust the base feet or insert stable materials (such as wooden wedges or rubber pads) to ensure the toilet is in a completely level state, avoiding inconvenience or structural damage due to tilting.

3. Pipe and Power Connections (if applicable)

   • Water Supply System: When connecting the water supply hose, ensure the interface is secure and leak-free, and install a check valve to prevent backflow.
   • Electrical System: If lighting or ventilation equipment is required, it should be operated by a professional electrician using waterproof sockets that comply with outdoor electrical safety standards (such as IP44 or higher protection ratings).

4. Auxiliary Facilities and Signage Setup
   Install anti-slip pedals and simple handrails around the toilet and set up clear signs at the entrance, inside, and around the area, including usage instructions, directional guidance, and emergency contact information, to enhance safety and convenience.

III. Material and Structural Advantages

The frame of mobile double-squat toilets is usually welded from steel, with wall materials including color-coated steel plates, fiberglass, or stainless steel, featuring lightweight, corrosion resistance, and easy lifting. Some designs are plug-and-play types, equipped with pre-installed sinks, squat toilets, and water pipes, requiring only a water source connection on-site, significantly shortening installation time.
