Boil Water Notice for Restaurants and Small Businesses: What You Must Do

For a household, a boil water advisory means a few extra bottles on the counter. For a restaurant, it means rewriting the workflow of an entire shift: every sink, every ice bin, every handwash station, every plate and every glass of water the customer assumes is safe.

Most health departments do not require a food business to close automatically when an advisory is issued. They require the business to operate differently — and to be able to show that it did. The operators who get through a multi-day advisory without a violation are the ones who prepared a written procedure before it happened.

This guide covers the practical rules that apply in most U.S. jurisdictions, the areas that get inspectors’ attention, and what to do when the notice is lifted.

First: read the notice, not the headline

Three types of notice exist, and they call for different responses.

• Boil water advisory: the water may contain germs. Boil or use bottled water for drinking, cooking, ice and handwashing.
• Do not drink advisory: the water may contain chemicals or toxins. Boiling does not help. Use bottled water for drinking and cooking.
• Do not use advisory: the water is unsafe for any contact, including skin. Close, or operate with an alternate water supply.

A “do not use” order is rare, and when it happens the correct answer is usually to close until the utility restores safe water. Our explainer on boil water advisory vs. order explains the differences.

Ice is the first thing to fix

Ice is water in solid form, and in a restaurant it touches nearly everything: drinks, seafood displays, salad bars, smoothies, iced coffee.

• Turn off ice machines connected to the water line.
• Discard all ice made before the advisory.
• Clean and sanitize the bin before making new ice.
• Buy bagged ice from a commercial supplier, or make ice from boiled-and-cooled or bottled water.
• Cover ice bins and use a dedicated scoop, never a glass.

The same applies to the ice in the walk-in freezer and to any ice used for display.

Handwashing stations

Handwashing is where advisories most often turn into violations, because the sink is the one place staff cannot avoid using water.

• Provide bottled or boiled-and-cooled water at each handwash station, with a dispenser and soap.
• Alternatively, set up a temporary handwash station with a container, a spigot, soap and paper towels, and keep it stocked.
• Do not let staff wash hands in a sink supplied with tap water and then handle food.
• Add hand sanitizer as a supplement, not a replacement. Sanitizer does not remove soil.

Document what you did. A log with times and the name of the person who set up the station is the kind of evidence an inspector appreciates.

Produce, ice baths and food preparation

• Wash produce with bottled or boiled-and-cooled water, not tap water.
• Do not use tap water for ice baths or for cooling pots in a sink.
• Do not use tap water to make beverages, including coffee, tea, lemonade, fountain drinks and mixed drinks.
• Soda fountains and post-mix systems are connected to the water line. Turn them off, or switch to bottled products.
• Steam tables and coffee brewers should be filled with safe water.
• Thawing should happen in the refrigerator, not under running tap water.

Dishwashing in a commercial kitchen

Commercial machines are usually better equipped than home dishwashers, but you still need to confirm the final rinse temperature.

• High-temperature machines should reach 180 °F (82 °C) in the final rinse, or 150 °F (66 °C) at the dish surface, depending on the machine and local code. Check the gauge and log it.
• Low-temperature machines rely on a chemical sanitizer; make sure the sanitizer is at the correct concentration and that the machine is not drawing tap water for the wash.
• Three-compartment sinks should use safe water for wash, rinse and sanitize. Change the water when it looks soiled.
• Air dry everything. Towel drying recontaminates.

What to tell customers

You do not need to post a legal notice on the door, but transparency protects you.

• Train staff to answer the question “is the water safe?” with a clear, honest answer.
• Offer bottled water and skip ice unless you have a verified safe supply.
• If you cannot meet the requirements, reduce the menu rather than the standards. A shorter menu is always better than a violation.
• Keep the utility’s notice and your response log on site.

Employees and facilities

• Provide drinking water from a safe source in the break room.
• Post the advisory in the staff area with the date and the actions taken.
• Tell staff not to drink from taps, sinks or hoses on site.
• If an employee becomes ill with vomiting or diarrhea, exclude them from food handling per your local rules — the same pathogens may be circulating.

Document everything

In a multi-day advisory, the inspector’s first question is “what did you do?” A simple log with these columns answers it:

• Date and time
• Task (ice discarded, station set up, produce washed with bottled water)
• Who did it
• Source of the safe water used

Photograph the setup: bottled water cases, the temporary handwash station, the sanitized ice bin.

When the advisory is lifted

1. Flush all water lines, including the ice machine, coffee brewer and soda fountain, per the manufacturer’s instructions.
2. Run ice machines through three batches and discard them.
3. Clean and sanitize ice bins, soda nozzles and beverage equipment.
4. Replace filters in ice machines, coffee brewers and point-of-use systems.
5. Run dish machines empty through a full cycle.
6. Restock handwash stations with normal supplies and remove temporary equipment.
7. Record the clearance notice in your files.

Frequently asked questions

Do we have to close? Not usually. A boil water advisory can be managed with bottled water, safe ice and documented procedures. A “do not use” order is different — expect to close or bring in an alternate supply.

Can we serve fountain drinks? No, unless the system is fed from a verified safe source. Offer bottled or canned drinks instead.

Can we wash dishes with tap water if the machine reaches 180 °F? Machine temperature helps, but the water itself is still the concern. Follow your local health department’s guidance; most require safe water for the wash and rinse.

What about coffee? Coffee is brewed with water that reaches high temperatures, but it is not a substitute for safe water. Use bottled or boiled-and-cooled water.

How long does this last? Typically 24 to 48 hours, sometimes several days. Plan for three days and hope for one.

Bottom line

A boil water notice turns a restaurant into a logistics operation. Ice, handwashing, produce, beverages and dishes all need an alternate water source, and every step needs a log entry. Do that, and you can keep serving safely while your neighbors are still arguing about whether to close.
