Ever wonder about the efficiency of our “modern” toilet and water-based sewage systems, or if they even really make sense? Dr. Lucas Dengel shares with us the argument for Ecological Sanitation, or “Ecosan,” from his practice and perspective in Tamil Nadu, India. Ecosan is a universal concept that can (should) be considered everywhere, with practices adapted to local needs and conditions. The transition to a better way of separating, treating and actually gaining benefit from our sewage may be easier said than done, especially in cities—as most common ecosan practices rely on outhouses and composting containers, not conveyance through large, multistory buildings. But it’s time to start shifting our thinking. There’s a real need for healthy sanitation worldwide, and there’s a lot to gain from waste.
The following is reprinted from a document written by Dr. Dengel in January 2011, with minimal edits. Dr. Dengel is a medical doctor who became interested in the prevention of disease, rather than just treatment, early in his career in India. Now an organic farmer and an expert in ecosan, he champions its adoption, along with the use of effective microorganisms (EM) in treating sewage and waste—both for the sake of public health and for their many other benefits. Dr. Dengel lives and works in Auroville, Tamil Nadu, India.

Ecosan – ecological sanitation
Why should there be a need for an alternative to flush sanitation?
