The Norokie Nature Farming School restroom project also includes building septic tanks, already under construction. Septic tanks are primary domestic sewer treatment units that separate and transform solid waste.

The septic tanks, an added and much-needed benefit, are crucial to fighting diseases, verminoses, and endemic diseases, like cholera, since they stop human waste from being directly discharged into rivers, lakes, water springs, or even on surface soil. They are essential to improve hygiene among rural populations.

Septic tanks are nothing but underground tanks that receive sewer – human waste and grey waters – retain the solid waste and then start the biological purification process of the effluents. These effluents must be filtered in the soil so that the biological purification process can be completed and thus eliminate the risk of contamination.
