Oasis Design is a wellspring of original content and designs which you won't find elsewhere.

We specialize in the nuts and bolts of sustainability—practical systems for living well, in harmony with nature and each other. These include designs for managing water, wastewater, energy, money and other resources.

Our goal is to live really well, on a small amount of well-managed resources, and help others do the same.

We don't need resource wars...we just need to make the most of our fair share.

There are several hundred pages of free information here on our web site, as well as an additional several hundred in our books and articles.

We hope you enjoy your visit, and find something which helps you thrive.

Yours, The Oasis Team
