3. Separate liquid urine from solid feces ("Pee in Bucket 1, Poo in Bucket 2"). When urine and feces mix inside a plastic bag or bucket, anaerobic bacteria immediately break down urea into pungent ammonia and hydrogen sulfide gas, creating a heavy, sloshing, foul-smelling liquid hazard. Keeping liquid urine in a separate jug or bucket from solid feces eliminates 90% of toilet odors and reduces solid waste bag weight by 80%.
4. Cover solid waste after every single use with a dry carbon cover material (never leave feces exposed). Scoop 250 to 500 milliliters (1 to 2 cups) of compressed pine sawdust pellets, wood shavings, coco coir (coconut peat), peat moss, or unscented kitty litter over solid waste each time someone uses the toilet to desiccate moisture, block flies, and smother odors.
5. Plug basement floor drains and ground-floor toilets if you hear gurgling during a flood. If municipal storm sewers surcharge, raw neighborhood sewage can reverse direction and fountain out of your lowest drain traps. Stuff a thick rag wrapped in a plastic bag (or thread an expandable rubber plumbing test plug) into basement shower and floor drains, and weigh down a flat board over the lowest toilet trap.
6. Set up a dedicated "Tippy-Tap" or two-basin handwashing station right outside the bathroom door. Because alcohol hand sanitizer does not reliably kill norovirus or Clostridioides difficile (C. diff) spores and cannot remove physical fecal soil from skin, provide a soap-and-water handwashing spigot using diluted bleach rinse water (50 ppm) alongside 60% to 80% alcohol hand rub.

Decision rule: when you can "pour-flush" vs. when you must go 100% dry¶

Many people assume that during any water outage, you can simply carry a bucket of swimming pool water or rainwater into the bathroom and pour it into the toilet bowl to flush. While pour-flushing works mechanically (pouring 4 to 6 liters / 1 to 1.5 gallons of water briskly into the bowl creates the siphon needed to clear the trap without filling the upper tank), doing so after certain disasters causes a severe biohazard inside your home.

How to build and operate the Twin-Bucket Emergency Toilet (Oregon RDNA / PHLUSH Standard)¶

Public health engineers at PHLUSH (Public Hygiene Lets Us Stay Human), the Oregon Office of Emergency Management, the New Zealand National Emergency Management Agency (NEMA), and the World Health Organization (WHO) recommend the Two-Bucket Urine-Diverting Dry Toilet as the safest, cleanest off-grid sanitation system for urban and suburban households.

Why one bucket fails and two buckets succeed¶

A healthy adult produces roughly 1.2 to 1.5 liters (40 to 50 fluid ounces) of liquid urine per day, which is normally sterile or very low in pathogens and consists of 95% water, urea, and mineral salts. By contrast, an adult produces only 150 to 250 grams (5 to 9 ounces, roughly the volume of one cup) of solid feces per day, which contains billions of enteric bacteria, viruses, and protozoan cysts. - When you mix urine and feces in a single bucket: The enzyme urease present in fecal bacteria reacts with the urea in urine, releasing clouds of ammonia gas while creating 10 liters (2.6 gallons) per day of heavy, sloshing, infectious liquid sewage for a family of four that tears trash bags and cannot be put in municipal trash bins. - When you separate urine (Bucket 1) from feces (Bucket 2): Urine smells mild when kept separate and can be diluted or disposed of easily, while solid feces buried under dry carbon sawdust dries out rapidly, smells like damp forest mulch, and weighs less than 1 kilogram (2.2 pounds) per day for an entire family.

Step-by-step assembly of a Twin-Bucket Toilet¶

Gather these inexpensive supplies today and store them nested together inside your garage or hall closet: 1. Two standard 19-liter (5-gallon) food-grade or hardware-store HDPE buckets (roughly 37 centimeters / 14.5 inches tall, which matches standard residential toilet height). Label the first bucket "BUCKET 1: URINE ONLY (LIQUID)" and the second bucket "BUCKET 2: SOLIDS & PAPER ONLY." 2. One snap-on plastic emergency toilet seat lid (available at any camping or hardware store for $10 to $15), or construct a seat top using a split foam pipe-insulation noodle pushed onto the rim of Bucket 2. 3. Heavy-duty bucket liner bags for Bucket 2 (Solids): Stock a roll of 30-to-50-liter (8-to-13-gallon) contractor-grade polyethylene trash bags (at least 1.5 to 2.0 mil / 38 to 50 microns thick) or certified ASTM D6400 compostable bio-bags containing an absorbent gel pad (such as Double Doodie or WAG Bags). Never use thin grocery store plastic bags, which have pinhole leaks in their bottom gussets. 4. Dry Carbon Cover Material ("Bio-Absorbent"): Store one 18-kilogram (40-pound) bag of compressed pine wood stove pellets / horse bedding pellets (costing around $7 at any hardware or farm store), untreated kiln-dried wood shavings, coco coir bricks, peat moss, or unscented clumping cat litter alongside a dedicated plastic scoop.

How to use the Twin-Bucket System after every bathroom visit¶

• For Bucket 1 (Urine Only, No Liner Bag):
• Pour 250 milliliters (1 cup) of water and 15 milliliters (1 tablespoon) of white vinegar or vegetable oil into the bottom of the bare plastic urine bucket (or use a 20-liter / 5-gallon screw-top water jug with a wide funnel). A thin film of vegetable oil floats on top of the urine, forming an airtight liquid vapor seal that traps urine odor inside the bucket, while white vinegar lowers the pH to stop ammonia formation.
• Do not drop used toilet paper into the urine bucket; drop all used toilet paper into Bucket 2 (Solids) or a separate lined trash bin so the liquid urine can be poured out cleanly without clogging.
• Empty the urine bucket once a day (see safe disposal rules below) and rinse with a splash of 1:10 diluted bleach water.
• For Bucket 2 (Solids & Toilet Paper, Double-Bagged):
• Line Bucket 2 with two nested heavy-duty bags and sprinkle a 5-centimeter (2-inch) cushion layer of dry pine sawdust, expanded wood pellets, or coco coir across the bottom of the inner bag before the first use.
• After defecating, drop used toilet paper into Bucket 2 and immediately cover all visible waste and paper with 1 to 2 cups (250 to 500 milliliters) of dry carbon cover material until nothing is visible.
• Close the snap-on toilet lid firmly to keep flies out.

Comparing dry cover materials and chemical coagulants¶

Safe temporary storage and final disposal of human waste¶

Once your solid waste bag in Bucket 2 is half to two-thirds full (never fill a bag to the brim, or it will be too heavy to tie and may burst), remove and store it using the Goose-Neck Double-Bag Seal: 1. Put on disposable nitrile gloves. 2. Sprinkle a final 2-cup layer of dry sawdust or kitty litter on top of the waste. 3. Gather the neck of the inner bag, press gently from the outside to expel excess air (without inhaling near the opening), twist the top of the bag tightly into a spiral, fold the twisted tail over itself in a U-turn (the "goose-neck"), and wrap it tightly with duct tape or a heavy zip tie. 4. Seal the outer second bag using the exact same goose-neck twist and tape method. 5. Place the sealed double-bag inside a dedicated animal-proof, tight-lidded outdoor garbage bin or 120-liter (32-gallon) heavy plastic brute barrel clearly painted or taped with the warning "HUMAN WASTE: BIOHAZARD, DO NOT MIX WITH RECYCLING." Keep this bin in the shade behind a locked gate so stray dogs, rats, raccoons, and children cannot breach the bags.

How to dispose of urine and bagged solids during and after the crisis¶

• Disposing of liquid urine (Bucket 1):
• If you have a yard or garden: Dilute the urine 5:1 or 10:1 with greywater (or pour undiluted in rotation) onto ornamental lawn grass, non-edible bushes, gravel mulched beds, or around the drip-line of mature trees at least 30 meters (100 feet) away from any well, stream, pond, or vegetable garden. Soil nitrifying bacteria rapidly convert urea into plant nitrogen without public health risk.
• If you live in an upper-floor apartment with no yard: Only if the building's vertical drainpipe is confirmed intact and unflooded on lower floors, pour liquid urine down the bathroom sink or tub drain followed by 1 liter of greywater to clear the P-trap; if the building sewer stack is broken or backed up, store urine in sealed plastic jugs or solidify it with super-absorbent sodium polyacrylate gel powder.
• Disposing of solid feces (Bucket 2 bags):
• Wait for municipal Emergency Waste Collection guidelines: In urban and suburban areas, keep double-bagged solid waste inside your lined outdoor containment bin until your municipal solid waste authority announces whether double-bagged emergency toilet bags may be placed in standard landfill collection trucks (most sanitary landfills accept double-bagged diaper and pet fecal waste under emergency waivers) or collected at dedicated neighborhood biohazard drop-off dumpsters.
• Rural Emergency Trench Burial (Only if you own rural land and municipal collection is suspended long-term): If you live on a rural property and must bury solid waste during an extended catastrophe, dig a narrow trench 0.6 to 1 meter (2 to 3 feet) deep located at least 60 meters (200 feet) downhill and away from any drinking water well, spring, creek, lake, or vegetable garden, and above the seasonal groundwater table. Empty the waste and biodegradable sawdust into the trench (do not bury plastic bags unless you have zero storage alternatives), cover each deposit immediately with 15 centimeters (6 inches) of compacted soil, and cap the trench with 45 centimeters (18 inches) of compacted earth once it reaches within 45 centimeters of the surface.

Handwashing and personal hygiene when zero tap water is available¶

During a sanitation emergency, your hands are the primary vector that carries microscopic fecal pathogens to your mouth, eyes, and food. According to the US Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), alcohol-based hand sanitizer (60% to 80% ethanol or isopropanol) is an important supplement, but alcohol hand gel alone does not reliably inactivate non-enveloped enteric viruses like norovirus or hepatitis A, does not kill bacterial spores, and fails when hands are visibly soiled.

How to build a Two-Basin or "Tippy-Tap" frugal handwashing station (Uses only 50 mL per wash)¶

Washing hands under a normal running bathroom faucet wastes 4 to 8 liters (1 to 2 gallons) of water per wash. Instead, build a gravity micro-flow station that washes hands thoroughly using less than 50 to 100 milliliters (2 to 3 fluid ounces) of water: 1. The Pressurized Jug Spigot or Poke-Hole Bottle: Take a clean 4-to-20-liter (1-to-5-gallon) plastic water jug with a bottom spigot, or poke a small 2-millimeter pinhole near the bottom base of a 2-liter plastic soda bottle filled with treated water. - How the 2-liter bottle trick works: When the top screw cap is twisted tight, atmospheric vacuum holds the water inside and zero drops leak out of the bottom pinhole. When you unscrew the top cap by a quarter-turn, a thin, steady stream of water flows out of the bottom pinhole so you can wet and rinse both hands without touching a dirty faucet handle; tighten the cap to stop the flow. 2. Add 50 ppm Chlorine to Your Handwashing Water: Add ¼ teaspoon (1.25 milliliters, or 25 drops) of unscented 5% to 8.25% household chlorine bleach per 3.8 liters (1 US gallon) of clear water in your handwashing jug. This mild 50 ppm chlorine solution sanitizes the wash water and helps kill surface pathogens during rinsing without irritating healthy skin. 3. Follow the 5-Step Emergency Handwash: Wet hands with a splash from the spigot, turn off the flow, lather vigorously with bar or liquid soap for 20 full seconds (scrubbing under fingernails and between fingers), rinse under the thin stream into a greywater catch bucket below, air-dry or dry with a single-use paper towel (never share a damp cloth hand towel among family members during a water outage, as shared cloth towels spread norovirus across an entire family in hours), and finish with a pump of 70% alcohol hand sanitizer.

Menstrual hygiene, baby diapers, and full-body bathing without running water¶

• Menstrual hygiene during water outages: Do not use reusable menstrual cups or washable cloth pads during a boil water advisory or severe water shortage unless you have abundant boiled water to boil the silicone cup for 5 to 10 minutes between cycles and scrub hands thoroughly before insertion; inserting a cup rinsed in contaminated tap water or with unwashed hands carries a serious risk of pelvic infection or toxic shock syndrome. Stock a 60-day supply of disposable unscented sanitary pads, unscented baby wipes, and small opaque zip-top disposal bags in your emergency kit.
• Disposable baby and adult incontinence diapers: Before tossing a soiled disposable diaper into your sealed outdoor waste bin, shake any solid stool off the diaper into Bucket 2 (Solids) and cover with sawdust, then roll the diaper tightly, secure the tabs, and seal it inside a barrier bag so fecal bacteria are contained. See infant and toddler emergency go-bag and evacuation plan.
• The 250-Milliliter (1-Cup) Sponge Bath: To prevent skin rashes, fungal infections, and heat illness without wasting water, warm 250 milliliters (1 cup) of boiled or treated water with a drop of mild no-rinse body wash (or diluted castile soap) in a bowl. Use two clean washcloths: one for the face, neck, chest, arms, and legs first, followed by the underarms, feet, and groin last, or use pre-moistened chlorhexidine or aloe no-rinse hospital bathing wipes.
