Biodigester Creates Better Environment
A biodigester toilet tank changes the environment in so many ways. It produces no foul smell. The water soaks into the surrounding soil, thereby increasing the amount of underground water. As a result, soil fertility raises and crop production improves. In addition, there is no wastewater discharge in the streets making it cleaner and most importantly safe.

The biodigester septic system has three parts:
- Grease interceptor
- Biodigester Toilet tank
- Soakage drain.
The drainage system from the house carries waste water, classified as either grey water or black water. Blackwater is sewage that has come into contact with toilet (faecal matter). On the other hand, grey water is sewage from kitchen sink and bathrooms.
Greywater has a lot of oils, fats, grease and detergents. As a result, it is chemically unstable. For this reason, it passes over the biodigester tank and goes through the grease interceptor to remove the oils. This is because the oils can be harmful to the environment. After this, the oil-free water goes to the soak pit.
Biodigester Toilet Tank
On the other hand, black water is directed into the biodigester tank. The already present anaerobic bacteria feed on the solid waste getting rid it of the waste and pathogens. The solid waste left settles at the bottom of the biodigester tank through sedimentation. Clear water through displacement goes to the soakage drain then percolates into the ground.
Displaced water from the tank goes to the soak pit where it soaks away to the ground . The water is about 98 per cent clean and free of pathogens. The water has a fertilizer effect, therefore, can replace inorganic fertilizers. As a result, it is great for use in irrigation purposes. However, it is not for human or animal consumption or cleaning in the house. This requires additional treating.
It is important to note that disposing non-degradable waste materials into the system is will affect the effectiveness of the system. Some of these materials include cigarette butts, sanitary pads, and condoms among others. If they disposed into the system, the system will block or fill up.
In addition, some cleaning detergents like phenyl are not appropriate for use. This is because they can harm the bacteria in the tank making it less effective. Replace them with the recommended cleaning detergents. Other liquids like paint and solvents can also harm the bacteria.
