Investigation of the potential of Bio-gas slurry as an odour suppressant in pit latrines.

Abstract

A pit latrine is the most basic form of improved sanitation which is currently used by a number of people around the globe. In spite of the wide spread use, known successes and advantages associated with pit latrines, they have received little attention in form of research and development. This review focuses on the usage and performance (filling, smell and odor control by bio gas slurry) of pit latrines in urban areas Kampala especially Kawempe and proposes approaches for their improvements and sustainability. Bad smell from human waste carries so many social, moral, aesthetic, and disease-related concerns that it represents a major barrier to successful sanitation adaptation for people all over Kampala. This study summarizes the odor control technologies for sanitation research in low- and middle-income settings from several toilets around Kampala especially in secondary schools. Research also addresses the often-overlooked issue of reduction of smell for effective sanitation promotion. The research argues that people therefore have developed strategies to avoid smell basing on the assumption of bio gas slurry as an odor suppressant, some of these being of concern to public health.
