Eco-sanitation Training

WMG's Eco-sanitation Technical Training provides you with in-class and hands-on instruction in the function, design, and construction of composting toilet systems for urban or rural environments.
Course description

The basic principle of ecological sanitation is to close the loop between sanitation and agriculture without compromising human health. In a closed-loop system, human feces and urine are treated as resources to benefit the surrounding environment, rather than waste products discharged to a conventional sewage treatment system. Successful eco-sanitation systems are hygienically safe, socially acceptable, economically feasible, environmentally sound, and technically appropriate. This course will give you an introduction to the concept of eco-sanitation, an overview of various types of composting toilets, human and environmental health considerations, and social acceptability of composting toilets. You will participate in the design and hands-on construction of a residential composting toilet.

This training is open to professionals, educators, and activists from a wide variety of backgrounds who have the capacity to implement the principles of eco-sanitation, either professionally or personally. The course combines classroom lectures with hands-on construction of a composting toilet system and tour of local eco-sanitation sites. WMG’s Water Harvesting Certification course is recommended as a prerequisite, but not required.
