A dry toilet, also known as a waterless toilet or dry toilet, is a sanitation facility that does not use water to flush and dispose of waste.
Aqua toilets work by mixing human waste with dry materials (such as sawdust, straw, sand, etc.) to break down and reduce odor. These materials absorb moisture from excrement, help keep it dry, and speed up the decomposition process. Dry toilets do not require the use of water for flushing, thus saving a lot of water resources.
Dry toilets do not produce sewage and reduce environmental pollution. Dry toilets are relatively low-cost to build and maintain, making them particularly suitable for resource-poor areas. Well-designed and correctly used dry toilets can effectively control the spread of infectious diseases and provide hygiene and safety.
Overall, dry latrines are a sustainable sanitation option that can provide basic sanitation in areas where water is scarce or resources are limited. However, in practical applications, appropriate design and management are required based on local environmental, cultural and community needs.
Precautions for building a dry toilet
1. Choose a suitable location: Choose a place to build a dry toilet away from water sources, residential areas and food storage areas. Make sure the surrounding terrain is elevated above the water source to prevent waste from leaching into groundwater.
2. Soil conditions: Choose a place with good soil permeability to build a dry toilet so that waste can be quickly decomposed and filtered. Avoid choosing areas with clay soil or drainage problems.
3. Build a suitable bottom: The bottom of the dry toilet needs to be built with a solid foundation to ensure its stability. The base may be constructed using concrete or other suitable material.
4. Install a suitable pit: Choose a pit of appropriate size so that it can accommodate a certain amount of waste. The depth of the pit is generally 1-1.5 meters, and the width and length can be selected according to needs.
5. Use appropriate materials: When building dry toilets, use materials that are durable, easy to clean, and corrosion-resistant. For example, it can be constructed using bricks, concrete or prefabricated aqua toilet modules.
