A water notice can change what is safe for drinking, food preparation or other uses. Read the exact instruction for your address; boiling and ordinary household filters do not solve every type of contamination.

Find the original notice
Use the water company's official website or verified contact channel and confirm the affected area and issue time. Read whether the instruction is to boil water, avoid drinking it or avoid using it. These are different restrictions. Do not replace the actual notice with advice copied from a different incident or country.
- Save the update page.
- Ask for accessible information if required.
Plan for ordinary household uses
List drinking, medicines, brushing teeth, food, infant feeding and pet care, then check how the notice affects each. Use supplied or commercially bottled water as advised. The baseline of three litres of drinking water per person per day does not cover all cooking, washing or individual requirements.
- Keep clean water separate from cleaning materials.
- Explain the notice to everyone using the home.
Wait for official changes
Continue the instruction until the water company updates it. Do not decide safety from clarity, smell or a home filter's appearance. Private supplies require local-authority advice after flooding. If you cannot obtain enough suitable water for a medical or care need, tell the provider or relevant support service early.
- Keep containers clean and correctly labelled.
- Do not improvise chemical treatment doses.
