Emergency Preparedness

BEFORE an Emergency

  • Learn how to operate shut-off valves to water lines, water heater and how to remove any covers. Keep tools handy. Mark valves and covers with fluorescent paint or tape to locate in the dark.
  • Brace, strap, or anchor the water heater
  • Store 3+ gallons of water per person and additional water for pets. Replace commercially bottled water by the expiration date. Any water treated with unscented bleach should be replaced after six months.
  • KEEP — extra water in all vehicles — unscented chlorine bleach or water purification tablets on hand
  • Do not add coloring/disinfecting products to toilet tank (a source of emergency water)
  • Store food and water away from household cleaners or contaminants

AFTER an Emergency

  • Check local news and this website, www.otaywater.gov to find out whether your tap water is safe before you drink or wash with it. Also, follow us on Facebook and Twitter.
  • Check pipes for leaks/breaks. If necessary, shut off main water valve to prevent contamination
  • Check if sewage lines are intact. If necessary, plug bathroom sink/drains to prevent backup
  • Avoid using food or water that may have been contaminated by untreated water (i.e. broken water/sewer/gas line, flood, etc.)
  • Don’t use pool/spa water as drinking water

  2. Then, do ONE of the following:
  • Boil water rapidly for 1 minute
  • Add water purification tablets per instructions
  • Add unscented chlorine bleach
    • - 4 drops bleach per 1 quart water
    • - ¼ teaspoon bleach per gallon water
    • - Let stand 30 minutes before using
