Here is a table on water chlorination for drinking safety. We do this and then rely on the on board water filter with carbon filter to remove the chlorine for use. Works pretty good and we are still alive.
Household bleach can be used. This should contain a 5.25% solution of sodium hypochlorite without soap additives or phosphates.
Use 1/8 teaspoon (about 5-8 drops) per gallon of water. Use only 5.25% sodium hypochlorite, such as Clorox bleach -- not scented or colorsafe.
4 drops regular liquid bleach per quart of water
16 drops regular liquid bleach per gallon of water
1 teaspoon regular liquid bleach per 5 gallons of water.
( for you non-metrics out there, like my humble self ! )
Amount of Water Amount of 5% Bleach to Add
1 gal. (4.5 litres), 2 drops (0.18 mL)
2-1/2 gal. (10 litres), 5 drops (0.4 mL)
5 gal. (23 litres), 11 drops (0.9 mL)
10 gal. (45 litres), 22 drops (1.8 mL)
22 gal. (100 litres), 3/4 teaspoon (4 mL)
45 gal. (205 litres), 1-1/2 teaspoons (8 mL)
50 gal. (230 litres), 1-3/4 teaspoons (9 mL)
100 gal. (450 litres), 3-1/2 teaspoons (18 mL)
220 gal. (1000 litres), 8 teaspoons (40 mL)
500 gal. (2200 litres), 6 tablespoons (90 mL)
1000 gal. (4550 litres), 6-1/2 ounces or 12 tablespoons (180 mL)
If bleach is more than one year old, it loses approximately 50% strength. In this case, the amount of bleach should be doubled. After treating with chlorine, mix well and allow water to stand 30 minutes before using. Use this eyedropper for no other purpose. If the bleach is not dated, at time of purchase, note the date on the bottle with a permanent marker.
