Drought: emergency water safety and conservation

Drought is a prolonged period of abnormally low rainfall leading to water shortages. Severe droughts strain municipal water supplies, damage crops, and increase wildfire hazards.

Do this now

  1. Store an emergency supply of drinking water: at least 4 liters (1 gallon) per person per day for 3 to 7 days.
  2. Follow all official municipal water restrictions issued by local utilities.
  3. Prioritize safe drinking water and essential hygiene over lawn watering or car washing.
  4. Keep emergency water purification tablets or unscented household bleach ready to treat unverified water sources.

Safe drinking water storage

  • Use food-grade plastic containers (such as heavy-duty water jugs or washed 2-liter soda bottles). Avoid milk jugs because residual protein fosters bacteria growth.
  • Store water containers in a cool, dark, dry area away from direct sunlight and household chemicals.
  • Rotate stored water every 6 months to ensure fresh taste and safety.

Emergency water purification methods

If public water supplies become contaminated or shut off during drought emergencies:

Boiling (Most effective method): - Bring water to a rolling boil for 1 full minute (3 minutes at high elevations above 2,000 meters or 6,500 feet). - Allow the water to cool naturally before storing in clean containers.

Disinfection with household bleach: - Use plain, unscented 6 percent or 8.25 percent liquid household bleach. - Add 2 drops of 8.25 percent bleach per 1 liter (1 quart) of clear water, or 6 drops per 4 liters (1 gallon). - Stir well and let stand for 30 minutes. Water should have a slight chlorine odor.

Home water conservation rules

  • Check for leaks: Fix dripping faucets and running toilets immediately. A running toilet can waste hundreds of liters a day.
  • Shorten showers: Limit showers to under 5 minutes or turn off the tap while soaping.
  • Reuse graywater safely: Collect rinse water from sinks or laundry to flush toilets manually. Do not drink graywater or use it on edible garden crops.

... note "Water safety" Never drink water from flood channels, radiator systems, or unverified industrial sources during a water emergency. Official guidance from the WHO and CDC governs drinking water disinfection standards.
