Field evaluation of an affordable, effective on-site sanitation system To further develop a technology based on biofilter technology and using the 'Tiger Worm'.
The project is facing the challenge of providing sustainable and affordable on‐site sanitation for low‐income households who either lack sanitation or who use a pit latrine.
The Tiger Toilet is a latrine system that has the potential to be an affordable, compact, and superior alternative to pit latrines and septic tanks. It harnesses the capabilities of composting worms such as the Tiger Worm (Eisenia fetida), to digest the solids within the system, making it very compact and particularly suitable to high density urban environments.
Mission
The project aims to address the global challenge of providing access to adequate sanitation; worldwide, over 4 billion people currently use latrines that can be unpleasant and unhygienic or lack sanitation provisions entirely. Sewered systems will never be a reality for many around the world; therefore an on-site (i.e. a system that does not require piping the waste off-site for treatment) option is needed. Presently the best on-site option is a septic tank, which is often financially out of reach.Approach
Contributing partners to this project include Oxfam, Water for People, and PriMove India. The initial development of the Tiger Toilet was funded through a grant from the Bill & Melinda Gates Foundation to the London School of Hygiene and Tropical Medicine (LSHTM). LSHTM is also supporting the current project by assisting BVV with the user evaluation of the system, which will assess users’ satisfaction with the Tiger System as well as their interest in purchasing the system. This project is funded under the USAID DIV scheme.Project description on USAID DIV website
