Mobile Toilet Sewer System

The installation, use, and maintenance of the sewer system for mobile toilets should follow the following key points to ensure their normal operation and hygiene safety:

1. Selection of Installation Location
The installation location of mobile toilets should meet the conditions of good ventilation and convenient drainage. Sufficient space should be reserved around the sewer outlet for subsequent maintenance and inspection. If installed indoors, it should be compatible with the building's drainage system; if used outdoors, the terrain slope should be considered to avoid rainwater backflow or sewage accumulation.

2. Sewer Pipe Connection Specifications

• Interface Matching: Select an appropriate sewer pipe interface based on the size of the sewage outlet, ensuring that the type (such as PVC, metal, etc.) matches the pipe material. Special sealing rubber rings or gaskets should be used at the interface to enhance sealing performance.
• Fixing and Extension: Firmly connect one end of the sewer pipe to the sewage outlet and extend the other end horizontally along the ground to the entrance of the drainage system. The extended section should be kept straight or slightly inclined downward (with a slope of ≥1%) to avoid blockages caused by bending.
• Sealing Treatment: Apply waterproof sealant evenly at the interface, covering the entire contact surface, and press it tightly until it fits snugly. The sealant should be a corrosion-resistant, anti-aging, and environmentally friendly material to prevent sewage leakage and environmental pollution.

3. Angle and Slope Control
The sewer pipe must be kept horizontal or vertical, with the inclination strictly controlled within a reasonable range (usually not exceeding 5%). If the slope is too steep, the fast flow of sewage may impact the pipe wall; if the slope is insufficient, it may lead to the deposition of excrement, causing blockages or backflow. A level can be used to assist in calibration during installation.

4. Regular Cleaning and Maintenance

• Daily Cleaning: Check the sewer outlet weekly for debris accumulation and use a soft-bristled brush or high-pressure water gun to flush the pipe wall to prevent the solidification of grease and paper scraps.
• Deep Unclogging: Use professional pipe unclogging agents (such as alkaline cleaners) monthly to dissolve organic matter or remove stubborn blockages with mechanical unclogging tools (such as spring-type uncloggers).
• Anti-freezing Measures: In cold winter environments, wrap insulation materials (such as rubber-plastic sponges) around outdoor sewer pipes to prevent freezing and cracking; when not in use for a long time, drain the water from the pipes.

5. Handling of Abnormal Situations
If slow drainage, odor diffusion, or pipe wall leakage is detected, stop using it immediately and investigate the cause: check the interface sealing, clear blockages, adjust the pipe slope, or replace aging components. Do not dismantle the pipes randomly; it is recommended to contact professional personnel for repair.
