The New Create an Oasis with Greywater

Art at Oasis Design wanted to let everyone know about the new edition of his book The New Create an Oasis with Greywater.

The book teaches you how to “quickly and easily choose, build, and use a simple greywater system. Some can be completed in an afternoon for under $30.

It also provides complete instructions for more complex installations, how to deal with freezing, flooding, drought, failing septics, low perk soil, non-industrialized world conditions, coordinating a team of professionals to get optimum results on high-end projects, and “radical plumbing” that uses 90% less resources.”

The Other Troublesome Water

Composting toilets solve the problem of blackwater (i.e., wastewater).

But the one large consideration that is often overlooked is that you also need to consider how to treat your bathroom and kitchen waste water, called “greywater.”

In traditional sewage or septic systems the toilet wastes are mixed in with the greywater and then treated.

Much of the world has water quality problems, and here we are spending money treating water to drink, and then we go and mix waste with it?!

So we have not needed to consider treating the greywater before.

With a potential composting toilet installation, you have to start thinking about treating the greywater. While greywater is often considered much less troublesome than septic tank effluent (blackwater), it still needs treatment, so you will need to consider this when looking into installing a composting toilet. In fact, in some areas greywater can be more difficult to deal with than blackwater because of the volume from sinks, showers, etc.
