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 were piloted in Cambodia in 2015-2016. The final design has been up-dated from that shown below.
