Most of components of the Twin Bucket Emergency Toilet can be found in a typical household or be obtained free or at low cost in most neighborhoods. The heart of this system is plastic containers, such as those used in the food industry. Since Federal regulations prohibit the commercial reuse of plastic buckets and barrels for food, containers are sold cheaply for other uses or simply dumped into land fills.
Think containers! For emergency systems every size is useful. Three and four gallon buckets usually discarded by bakeries come with good lids and work for the twin toilet, particularly for kids. You can store water and carbon material in square receptacles. The Tap Up handwashing apparatus can be fashioned from smaller buckets. Large 55-gallon barrels in which food is transported are excellent for rainwater harvesting and long term composting. Wheeled recycling barrels can be used for both storage and transport. So keep your eyes open for plastic containers and collect and store as many as you can.
Other items for readiness. Disposable plastic gloves, hand sanitizer, remoistened wipes, toilet paper, and print copies of Twin Bucket Emergency Toilet leaflet and A Sewer Catastrophe Companion. Depending on your situation you may fashion a dedicated sanitation kit, integrate sanitation supplies in a general kit, or simply rotate household supplies, ensuring you have sufficient reserves for an extended emergency.
Please note! Vendors are listed below but that does not mean we’ve tested and endorse. Most suppliers of emergency toilets and components mistakenly assume that users have disposal options. A Cascadia Subduction Zone quake is likely to destroy piped systems so plan accordingly to use dual containers to separate pee and poo.
Supplies for the Twin Bucket Emergency Toilet
Buckets: Buckets in various colors with lids that fit can be ordered here.
Seats: Plastic seats need to be purchased unless you fit standard toilet seats to containers.Plastic toilet seats generally fit cylindrical buckets ranging from 3 to 7 gallons. Get them at emergency suppliers (The Preparedness Center, QuakeKare, Emergency Essentials, etc), at camping stores (Andy and Bax, REI, Cabela’s,Gander Mtn, etc) or from Amazon.com. The Preparedness Center offers a flexible seat as part of a bucket toilet. While you can remove the toilet seat from your bathroom toilet and duct tape it on a bucket, it’s best to have a seat which you can easily shift from bucket to bucket.
Bucket toilets: Emergency Essentials and Tote-able offer bucket toilets with snap-on seat and seat cover for about $15. Add found buckets to separate pee and poo and move the seat from one to another.
Carbon substrate to compost poo: Ask your local lumberyard for sawdust and the coffee roaster for coffee husks. Save bags of shredded paper. If you don’t have a much space, buy wood pellets or coconut coir fiber bricks as these expand when a small amount of water is added. (Add 1.25 liters of water to a brick-sized coir brick to yields 8 or 9 liters of friable carbon coverning material.) Many options are available on Amazon.com. Check out this 250 gram coir fiber brick for $1.13 and 40-lb bag of wood pellets for $5.99
Make a kit? For about $40 you can get everything required for a nested bucket sanitation kit that makes a fine and loving gift.
