Ever scratched your head trying to find safe excreta disposal solutions for pour flush latrines in congested urban slums, remote locations, high water tables, rocky ground and no-network areas? Well, this webinar could have the answers you've been looking for.
The worm based sanitation project in Monrovia was designed by Oxfam and inspired by the Biofil (from Ghana) and Tiger Toilet systems. This novel system aims to tackle the challenges of excreta disposal where de-sludging is not possible and was designed for pour flush latrines (where waste is disposed of directly into an above ground concrete chamber). The worms live in a bedding material (coconut fibre which has been soaked for 24 hours in water) and eat the waste flushed into the chamber. Excreta are deposited on this bedding material whilst the liquid is filtered through a media of gravel, charcoal and sand. The effluent produced is collected in an external sump, which is then emptied by the householder.
After 3 years there is virtually no waste to remove from the chamber as the worms eat and excrete nominal amounts. This approach of course requires community engagement, understanding and pro-activeness before, during and after the installation of the system.
