Disinfectants
The best choice is a solution of 1 part liquid chlorine bleach to 10 parts water. Other commercial disinfectants include HTH, or calcium hypochlorite, which is available at swimming pool supply stores; portable chemical toilets, which are available through recreational vehicle supply stores; and powdered, chlorinated lime, which is available at building supply stores.
Emergency Sewage Disposal
Many times during a disaster people are not only left with contaminated water, but also
they may not even have access to any running water at all. Faucets run dry, and toilets will not flush. It is imperative that human waste be disposed of properly, so as to keep an area free of contamination.
Always have basic sanitation supplies on hand:
-Medium-sized plastic bucket with tight lid.
-Plastic garbage bags and ties (heavy duty)
-Household chlorine bleach
-Soap, liquid detergent
-Toilet paper
-Towelettes
If sewage lines are broken but the toilet bowl is usable, place a garbage bag inside the bowl. If the toilet is completely backed up, make your own. Line a medium sized bucket with a garbage bag and make a toilet seat out of two boards placed parallel to each other across the bucket. An old toilet seat will also work.
How to Sanitize Waste
After each use, pour a disinfectant (see Disinfectants) such as bleach into the container. This will help avoid infection and stop the spread of disease. Cover the container tightly when not in use.
How to Dispose of Waste
Bury garbage and human waste to avoid the spread of disease by rats and insects. Dig a pit 2 to 3 feet deep and at least 50 feet downhill or away from any well, spring, or water supply.
If the garbage cannot be buried immediately, it should be stored in a manner so as to not contaminate your living area. Keep on the premises at least one extra 10-gallon garbage can or other waterproof container with a tight fitting cover. This should be lined with paper and/or a plastic bag. And the lid should be fastened to the can to prevent its loss. Such a can may be used for the emergency storage of body wastes until the public sewage system can be put back into action, or until other arrangements can be made. Empty your emergency toilet into this storage can as often as necessary. A small amount of household disinfectant should be added after each use. If you live in an apartment, you may not have a large garbage can or room to keep one. In that case, two smaller covered pails or other containers will do just as well.
Persons in city apartments, office buildings, or homes without yards should keep a supply of waterproof paper containers on hand for emergency waste disposal. Where flush toilets cannot be used and open ground is not available for the construction of privies, such disposable containers offer a practical method of emergency waste collection and disposal. Building managers should plan for the collection of such containers and for their final disposal. Before collection, the used containers may be stored in tightly covered garbage cans or other water tight containers fitted with lids. Homemade soil bags for this purpose can be prepared very easily by putting one large grocery bag inside another, and a layer of shredded newspaper or other absorbent material between. You should have sufficient grocery bags on hand for possible emergencies. A supply of old newspapers will come in handy for other sanitary uses also, such as wrapping garbage and lining larger containers.
