Summary

On-site sanitation systems (OSS) remain the dominant household arrangement across the state of Tamil Nadu for urban sanitation. Given that these OSS are spread over different hydrogeological zones, factors such as aquifer systems, soil drainage characteristics, groundwater levels and flood hazard areas have a bearing on their suitability. A study was undertaken for the state of Tamil Nadu to understand how these factors collectively determine the suitability of OSS systems. This report presents the findings of this study.
