What does dry toilet mean?

Dry toilets, also known as waterless toilets or dry toilets, are sanitary facilities that do not use water to wash and treat wastes.

The working principle of dry toilets is to decompose and reduce odor by mixing human excrement with dry substances (such as sawdust, straw, sand, etc.). These materials can absorb water from excreta, help keep it dry and accelerate the decomposition process. Dry toilets do not need to be flushed with water, which saves a lot of water resources.

Dry toilets do not produce sewage, which reduces the pollution to the environment. The construction and maintenance cost of dry toilets is relatively low, which is especially suitable for areas with scarce resources. Well-designed and correctly used dry toilets can effectively control the spread of infectious diseases and provide health and safety guarantees.

Generally speaking, aqua privy is a sustainable choice of sanitary facilities, which can provide basic sanitary conditions in areas with water shortage or limited resources. However, in practical application, it needs to be properly designed and managed according to the local environment, culture and community needs.

Matters needing attention in building dry toilets

1. Choose a suitable location: choose a place far away from water sources, residential areas and food storage areas to build dry toilets. Ensure that the surrounding terrain is higher than the water source to prevent garbage from infiltrating into the groundwater.

2. Soil conditions: choose a place with good soil permeability to build a dry toilet, so that the garbage can be quickly decomposed and filtered. Avoid choosing clay or areas with drainage problems.

3. Build a suitable bottom: The bottom of the dry toilet needs to build a solid foundation to ensure its stability. Concrete or other suitable materials can be used to build the bottom.

4. Install a suitable pit: Choose a pit with a suitable size to hold a certain amount of waste. The depth of the pit is generally 1- 1.5m, and the width and length are selected as required.

5. Use suitable materials: When building dry toilets, use durable, easy-to-clean and corrosion-resistant materials. For example, brick, concrete or prefabricated dry toilet modules can be used for construction.
