The Composting Toilet System Book [return to top]

Learn about a world of composting toilet and graywater system options!

From cottage toilets to whole-house composters with micro-flush toilets and graywater gardens, The Composting Toilet System Book covers a wide realm of ecological toilet options.

Composting toilet systems and other ecological wastewater management methods are emerging as viable and cost-saving alternatives to wastewater disposal systems worldwide. The book details why--and how to choose, install and maintain them.

In this book, you will find

  • Descriptions of more than 40 systems--both manufactured and site-built--and their sources
  • Compatible toilet stools and micro-flush toilet installation tips
  • Tips on choosing, planning, installing and maintaining your composting toilet system (including what manufacturers won't tell you!)
  • The experiences of owner-operators worldwide
  • What you should know about graywater systems
  • Regulations and advice about getting your system approved

The Composting Toilet System Book contains the information you need to choose and maintain composting toilet systems and other alternatives to sewer and septic systems. Long used by off-the-grid homeowners, parks and cottage owners, composting toilet systems are now making their way into conventional year-round homes. The technology has improved and is available in styles compatible with upscale bathrooms. In addition to providing technical information on various systems, the book profiles composting toilet system applications worldwide, provides United States permitting information, and features key maintenance and operation information that the manufacturers do not provide. The book also contains information about using these systems with graywater systems and flush toilets. Find out how you can have a smaller leachfield, reduce pollution, and help arm yourself and your community against the skyrocketing water and sewage costs of the future.

The book is co-authored by David Del Porto, who has sold and serviced thousands of several models and brands of composting toilet systems since 1972. He has also helped write regulations and performance standards for these systems, and has designed composting toilet and graywater systems for Greenpeace and for developing countries.

Liquid Gold
The Lore and Logic of Using Urine to Grow Plants
[return to top]
by Carol Steinfeld • Illustrations by Malcolm Wells

ISBN: 0-9666783-1-1$12.95

Every day, we urinate nutrients that can fertilize plants that could be used for beautiful landscapes, food, fuel, and fiber. Instead, these nutrients are flushed away, either to be treated at high cost or discharged to waters where they overfertilize and choke off aquatic life.

Liquid Gold: The Lore and Logic of Using Urine to Grow Plants tells you how urine--which contains most of the nutrients in domestic wastewater and usually carries no disease risk--can be utilized as a resource. Starting with a short history of urine use--from ritual to medicinal to even culinary--and a look at some unexpected urinals, Liquid Gold shows how urine is used worldwide to grow food and landscapes, while protecting the environment, saving its users the cost of fertilizer, and reconnecting people to the land and the nutrient cycles that sustain them. That's real flower power!

Liquid Gold features three ways to use urine hygienically and productively for plant growth, with studies that show the science behind this practice. Several advocates of urine diversion and their gardens are profiled, demonstrating that using urine for fertilizer is a feasible, safe, and cost-saving way to prevent pollution and save on fertilizer costs.

Reusing the Resource: Adventures in Ecological Wastewater Recycling
by Carol Steinfeld and David Del Porto
7.75 x 9144 pages300+ color photos and diagrams$24.95

Imagine a future in which gardens, greenhouses and groves of trees replace sewage outfall pipes and leachfields. Sewage will grow ecological tree plantations that provide fuel, fiber, construction materials, wildlife habitat and beautiful landscapes. A pig farm's wastewater will fertilize a tree farm instead of pollute a river. A house's wastewater will irrigate and fertilize its surrounding landscape. A planted roof will collect and filter rainwater for use in the house.

Plans for Composting Toilet and Graywater Systems

EcoWaters Net-Barrel Composting Toilet System
Originally designed for an eco-tourism resort in Fiji, the 55-Gallon Net Batch system is an inexpensive solution that uses reused 55-gallon drums (or you can use rollaway trash bins) and an effective aeration mechanism that maximizes the composting material's surface to volume ratio. That means faster and more thorough composting. The capacity is as expandable as the number of reactors (drums) used. Plans include design for a simple Wastewater Garden to manage leachate and, expanded, graywater, too!

$30 (includes postage--U.S. only; non-U.S. add $5 postage)


Ecowaters Twin-Bin Net Composting Toilet System
This design is an advancement of the classic two-vault composter system used worldwide. The difference: Improved aeration mechanisms that gets more air to the composting material and manage leachate. First used by Greenpeace for its appropriate technology and ecotourism projects, this system has proven successful in the South Pacific islands, Mexico and even cooler regions of the U.S., for its high efficiency, low maintenance and low construction cost.

Dam Nation: Dispatches from the Water Underground
return to top]

This essay anthology looks at water issues worldwide and throughout history, including science, history and investigative reporting, as well as personal stories and profiles. Among other concerns, writers collected here-mostly activists, but also sociologists, educators and reporters-address untreated sewage dumping and the disease outbreaks it causes; the destructive power of upstream dams; and the sediment-starved Mississippi Delta, its attendant erosion, and the horrific storm damage that's resulted. A short, frank multi-millennial history of urban sewage disposal illustrates well the dangers of water supplies contaminated by sewage-cholera, typhus, typhoid, etc.-and is equally forthright about the problems with current municipal sewage treatment practices. The authors maintain a tongue-in-cheek style that, for the most part, keeps tedium at bay; if readers find Part One too polemical, Parts Two and Three offer principles and proper construction techniques for practical, at-home solutions, including home watergardens, home-scale graywater wetland systems.
