Here are some things that homes without running water can do using household bleach.
Using bleach to disinfect surfaces
Using a handwashing basin
If you use a handwashing basin, make sure the water in the basin is changed regularly during the day.
Consider adding a small amount of bleach to basin water, so that germs don’t grow.
Add 1 teaspoon liquid bleach to a half gallon of water. This will create a mild bleach solution, slightly stronger than pool water.
Having two separate basins is best – one for soapy wash water and one for clean rinse water (with bleach).
