How to Prepare for a Planned or Unexpected Water Service Interruption
A household checklist for a water outage, from saving the official notice to restarting service after it returns.

Confirm what is happening and when
For planned work, the provider may give a service window, affected streets, and preparation instructions. For an unplanned interruption, use the utility’s official outage page, phone line, or alerts for updates. Record the time service stopped and avoid relying on rumors or posts that do not identify the provider.
If there is flooding, a broken main, or unsafe conditions near utility equipment, stay away and report the situation through the emergency channel.
Set aside what the household needs
Before a planned interruption, fill clean containers for drinking, basic food preparation, hand washing, and pets, following any local instructions. Consider the needs of children, older adults, medication routines, and household members who use water-dependent equipment. Keep containers covered and separate from cleaning supplies.
If the interruption is unexpected, do not assume the remaining tap water is safe to drink. CDC advises using bottled, boiled, or treated water as directed after a main break, flood, or other emergency. The utility or health department will say whether there is an advisory and what applies to your address.
- Charge phones and keep emergency contacts accessible.
- Pause appliances that need a water supply.
- Know how to turn off a household appliance if its manufacturer recommends it.
- Keep the provider’s return-to-service instructions handy.
Plan for plumbing, food, and medical needs
Avoid running appliances that expect a steady water supply. Keep refrigerator and freezer doors closed during a related power outage, and plan alternatives for sanitation if the interruption will last. If a household member depends on medical equipment, dialysis, home care, or temperature-sensitive medication, follow the care plan and contact the relevant provider early.
When water returns
Follow the utility’s directions before using the water normally. The provider may advise a brief flushing step, a temporary advisory, or no action at all depending on the work performed. If water pressure, color, or odor concerns persist after the stated guidance, report them to the utility.
Keep a short household record
Save the notice and note any property issue, unusual meter activity, or interruption-related cost. A clear timeline helps when you need to communicate with the provider, landlord, insurer, or a repair professional.
