Installation of Mobile Toilets in Rural Indoor Areas

When installing mobile toilets in rural indoor areas, you can choose between factory-prefabricated finished products or self-made modifications, depending on actual needs and conditions.

Factory-Prefabricated Finished Mobile Toilets

Factory-prefabricated finished mobile toilets are a more convenient option. Their internal water supply and drainage systems are pre-installed, and only external connections need to be made during installation before they can be put into use, eliminating the complex process of on-site construction and suitable for scenarios with high requirements for construction efficiency. Some products support customization. For example, the mobile toilets provided by Henan Hemai Industrial Co., Ltd. are made of materials such as color steel plates or metal carved plates, offering good durability and thermal insulation. They come in specifications like 1.3×1.3×2.35 meters and 1.1×1.1×2.35 meters, allowing flexible selection based on indoor space. With an applicable temperature range of -35℃ to 100℃ and a voltage of 220V, they can meet the anti-freezing needs of rural areas in northern China in winter, preventing pipeline freezing or equipment damage due to low temperatures.

Self-Made Modification Plan

If you choose to make modifications yourself, you can refer to the toilet modification cases in northern rural areas and solve the problem of fecal water treatment by building a three-compartment septic tank. The specific steps include:

1. Excavate the pit: Dig the pit for the septic tank according to the design specifications. The depth should take into account the thickness of the local permafrost layer, ensuring that the septic tank is located below the permafrost layer to prevent freezing in winter.
2. Build compartments: Use bricks or concrete to build three connected compartments, serving as the sedimentation tank, fermentation tank, and fecal storage tank respectively. Over-flow pipes should be installed between the compartments to ensure the gradual flow of fecal water.
3. Install pipelines: Connect the sewage pipeline between the indoor toilet and the septic tank. The pipeline should be made of anti-freezing materials and set at a certain slope to prevent the retention or blockage of fecal water.

Key Design Considerations

Whether choosing a finished product or making modifications yourself, the following design aspects should be emphasized:

• Anti-freezing: In cold winters in northern rural areas, it is necessary to ensure that pipelines, septic tanks, and other facilities are located below the permafrost layer or wrapped with thermal insulation materials.
• Anti-overflow: The capacity of the septic tank should be reasonably designed according to the family population and usage frequency, avoiding the overflow of fecal water and environmental pollution.
• Anti-pollution: The septic tank should be sealed to prevent rainwater infiltration or fecal water leakage, avoiding pollution to the soil and groundwater.
• Anti-odor: Install ventilation pipes or use anti-odor floor drains, reducing indoor odors and improving user comfort.
• Anti-blockage: The pipeline diameter should be sufficient to avoid blockage by debris. Regularly clean the septic tank and pipelines to ensure the smooth operation of the system.
