Willow Feeder eBook
Most of today’s waste systems like septic tanks, sewage plants, composting toilets, and porta potties create what Paul Wheaton calls “poop koolaid” that ends up polluting our rivers and oceans.
The Willow Feeder changes everything. Instead of toxins and waste, it transforms nutrients into giant willow trees while keeping water clean and ecosystems safe. No stink, no flies, no pollution, only abundance.
What You’ll Find Inside
- Why traditional waste systems fail our environment
- How the Willow Feeder works as a stronger alternative to composting toilets
- Step by step breakdown of designs, from the “Cooper Pooper” to the “Willowonka”
- Solutions for gardeners, homesteaders, RV users, and even cities
- 140 pages long
- .pdf format
Willow Feeder Movie
A willow feeder is a simple yet groundbreaking waste system that keeps human waste out of water systems entirely. Unlike composting toilets, it separates poop from urine and greywater, stores it for two years to eliminate pathogens, and then uses it as nutrient-rich fertilizer for willow trees. The result is cleaner rivers and oceans, safer pathogen management, and a low-cost, sustainable solution for any home or community.
The Willow Feeder Movie captures 14 years of design, testing, and real-world builds. You’ll see exactly how the system works, why it’s better than sewage treatment plants, and how you can build one yourself.
In the Movie You’ll See
• What a willow feeder is and how it differs from composting toilets
• Why conventional sewage plants pollute and how willow feeders solve the problem
• Step-by-step builds of the Cooper Pooper (indoor) and WilloWonka (outdoor)
• How to collect, store, and safely use poop as fertilizer
• Why willows are ideal for nutrient cycling and how to plant them
• Pathogen management that outperforms sewage treatment plants
• How to operate at less than 10% of the cost of conventional systems
• Ways to reduce chemicals and contaminants in greywater
• Bonus benefits like solving “peak phosphorus” and improving soil health
• Lessons from over a decade of field testing at Wheaton Labs
Indoor Willow Feeder Plans
The Cooper Pooper is the first fully indoor willow feeder built at Wheaton Labs. Unlike outdoor or skiddable systems, this one is integrated directly into Cooper Cabin. It keeps human poop out of rivers and groundwater while offering the comfort of an indoor bathroom. Solids are stored in a tall sealed can, liquids are diverted to a greywater line, and a solar-powered fan ensures odor-free use.
The PDF includes 39 pages of detailed building instructions, drawings, and notes.
In the PDF Plans You’ll See
• Complete tools and materials lists, including framing, fasteners, and plumbing parts
• Step-by-step build instructions for the box, framing, access hatch, steps, and raised platform
• How to cut and install the seat platform with a properly placed urine diverter
• Details on the solar-powered ventilation fan for reliable odor control
• Proper placement and use of a 32-gallon collection can under the seat
• How to route the urine line into a mulch pit or greywater sink drain
• Guidance for creating a comfortable and safe step-up platform
• Clear diagrams for door framing, hinges, sealing, and can removal
• User guidelines on sawdust use, lid closing, and maintenance
• Lessons learned from the first indoor willow feeder build at Wheaton Labs
Outdoor Willow Feeder Plans
The Outdoor Willow Feeder (WilloWonka) is a skiddable outhouse design that keeps human poop out of rivers and groundwater. Unlike composting toilets or septic tanks, it separates poop from urine and greywater, stores solids in sealed cans to age safely, and uses them as nutrient-rich fertilizer for willows and other trees. The trombe wall ventilation system moves air with the sun, meaning no fans, no smell, and no electricity.
The PDF includes 58 pages of detailed building instructions, drawings, and notes.
In the PDF Plans You’ll See
• Complete materials list including roundwood sizes, hardware, and plumbing parts
• Step-by-step build instructions for skids, posts, beams, rafters, roof, siding, stairs, and hatch
• How to install a urine diverter and connect it to a mulch pit for safe greywater use
• Trombe wall details for natural passive airflow and odor control
• Seat design, bucket clearances, and sealing tips for everyday ease of use
• How to add a fly trap to the vent stack for cleaner, safer operation
• Guidelines for aging and safely cycling nutrients back to trees
• Practical safety notes for working with roundwood and tools
• Why this design outperforms septic systems at a fraction of the cost
• Lessons learned from real-world testing at Wheaton Labs
