Sanitation systems and technology options

Working Group 4

This working groups aims at delivering adequate information on all sustainability criteria of different sanitation systems and technologies. This includes possible sanitation technology configurations, and will facilitate decision making, implementation and operation.

Background: Why focus on sanitation systems and technology options?

Appropriate technology plays a crucial role for every sanitation system. Together with economic considerations, it is a decisive factor for the success of a sanitation system. One of the challenges for improving sanitation in low and middle income countries is to acquire sound knowledge of the wide range of sanitation options to assure informed decision making for the most feasible sanitation system.

This technology should be chosen according to health and hygiene as well as ecological, economical and financial factors and should best fit to the site-specific context. The technology selected should consider the entire sanitation chain, from the point of excreta generation through collection, transportation, treatment and safe use of treated material.
