In this article about how to construct a simple onsite biodegradable biodigester, I will implore you to take into account the following points in your next digester toilet construction journey;
The soil type and water table conditions in the area where the new toilet will be constructed should be considered while choosing the location of a simple onsite biodegradable toilet biodigester.

The best place for a biodigester to be installed is somewhere with sandy soils and good drainage. This will enable the digester to be fully buried.
On the other hand, when constructing a biodigester in a location that is less than ideal, such as an area that is waterlogged, the constructor of the digester must ensure that it is installed at a depth that ensures it will never be submerged in water, not even during the rainy season.
The depth to the surface in a specific area that is saturated with groundwater is commonly used as a measurement for the water table.
It is critical to remember that the weather and seasonal changes frequently cause the water table in a particular area to change.
Therefore, the placement of a biodigester should take into account the highest water table condition that exists at a particular site as well as the immediate surroundings of the digester.
Digging a hole and measuring the depth to which the water has saturated the soil is a reliable method for estimating the depth of the water table in a given area.
When there is a high water table close to or at the surface of the ground, the digester should be located either on top of or just slightly below the ground.
Look at the picture below.
In an ideal situation, and assuming that the water table is located anywhere between the surface of the ground and around 4 feet below the surface, the toilet digester can be built at a depth of only half that, approximately 1.5 feet into the ground.
When extreme conditions cause the water table to drop to a depth of less than 4 feet, the digester can be built to its maximum depth, with less than 1 foot protruding above the surface of the ground.
Note: It’s not necessary to place a vent pipe on top of a biodigester. The plumber can also do this on the PVC pipelines coming from the building.
