Sanitation in Challenging Environments: Flood Prone and High Groundwater

Wetlands Work has developed treatment for households in extreme environments, such as areas with permanent or seasonally high groundwater tables, or in flood-prone regions. Our general design consists of three stages, as shown below.  The design takes only 6 m2 of space, relies on gravity flow and an appropriate retention period for anaerobic and aerobic microbial activity. Fifty systems are currently being piloted in Cambodia.
