Are waste stabilisation ponds barriers to or reservoirs for cholera? Final Report for DFID.
The purpose of this project was to address strategically important gaps in our knowledge of the fate of toxigenic Vibrio cholerae in wastewater and waste stabilization ponds (WSP). In particular, it investigated the possibility that WSP might be sources rather than barriers for the pathogen. The research evaluated methods for detecting and quantifying V. cholerae in wstewater, and evaluated removal of toxigenic strains of V. cholerae in WSP. The results established that WSP are a barrier to V. cholerae O1 and O139 and that wastewater reuse using this technology can be promoted with confidence.
