Bio Toilet unit - 2018

Our Current toilet model is Bio toilet. After several trial and errors, Sewa has been building the bio toilets since 2018 . Once it is built, it needs only once a year inspection.

We have two toilet models :

• First one is brick and motor non portable model suitable for permanent residents of Rural areas with low cost bio digesters.
• Second one is portable prefabricated ferro cement slab toilet unit with low cost bio digester suitable for both Urban and Rural areas.

Basic features:

• Bio toilets saves groundwater contamination.
• Bio toilets are economical, low maintenance and eco friendly.
• It is a perfect alternative to the dumping of waste in the ground, especially in rural areas.
• Bio-toilet can be defined as a system in which human waste is biologically degraded into gas and water with minimal or no use of water
• It is an innovative method to decompose waste in an eco-friendly and economical manner.
• Within the bio digester pits, waste comes in contact with the bacteria, it is broken down and converted into carbon and methane gas and water. The methane gas released can be used for energy purposes and water for irrigation.
