Using high-quality water to flush our excrement is a bad idea for many reasons—the main reason being that it is a waste of clean water. Sewer systems are good, especially when they return the end product to the land, but it is expensive in terms of transport and resources. There have been experiments with bio-digesters—systems that turn sewage into gas—but really this only works on a town- or community-wide scale or for farmers who have mountains of manure to dispose of. A cesspool is no more than a pit that needs emptying, and it still needs the water flush. Septic tanks are good solutions for those who live in the country; while it still uses water, it could be gray water. Currently, one of the best options in the context of self-sufficiency is to use a system, such as those made by the global company Clivus Multrum, that turns the waste into compost—a modern spin on my grandfather’s process of burying the waste for a couple of years and then putting it back onto the land.
