Boil Water Advisory Guidance for Restaurants and Businesses

Restaurants must inform public if on a boil water order

Why Are Boil Water Notices Issued?

Every year, thousands of “BOIL WATER ORDERS” are issued in cities throughout the U.S.

These “alerts” or “advisories” are issued when there is a strong possibility of bacterial contamination in the drinking water. By law, city governments and municipal water suppliers must inform the public if unsafe water conditions arise.

Three reasons boil water orders are issued:

1. Water utility company's disinfection equipment cannot function properly due to a power outage

2. Distribution pressure drops below 20 psi due to burst pipes, water main break, etc.

3. Weather-related power outages are the biggest culprit. Outages are common during a hurricane or severe winter storm, such as the recent winter freeze in Texas where 1,259  boil-water notices were in effect, affecting millions of people.

A study conducted by the University of Missouri found that water service disruptions can cause business losses ranging from CA$141.00 to CA$563,986.44, and that, “Some food and beverage establishments required significant steps to ensure food safety, while others opted to close for the duration or for a portion of the disruption.

Can a Restaurant Operate During a Boil Water Advisory?

Some restaurants and grocery stores find it is easier to close their doors during a boil water notice. But others find ways to remain open by buying bottled water or somehow treating their water.
 
Boil water notices often cause a huge loss in revenue for restaurants, grocery stores, and other businesses in the food industry.
restaurants can still operate during a boil water notice
In order to operate under a boil water notice, restaurants must comply with their city health department requirements or stay closed and lose money.
 
Every time an advisory is issued in a city, hundreds of restaurants and businesses go to great effort and expense to ensure they do not put the public at risk.
 
For example, when the residents of Corpus Christi, TX experienced a wide-spread power outage and subsequent boil-water notice, one Corpus Christi coffee shop shipped ice in all the way from Dallas and used bottled water to prepare food and beverages for customers.
 
A recent water main break in St. Johns County, FL left 37,000 people under a Boil Water Advisory. Florida’s Health Department issued statutes to be observed by those in the food industry during the boil water notice--and the list of statutes is not a short one.
 
When millions of Boston residents were under boil-water orders, The U.S. Food and Drug Administration (FDA) issued an emergency guideline to food makers telling them to stop water usage while the boil-water advisory is in effect or heat, treat or filter the water prior to use.
How to keep business open during boil water advisories

Four Ways a Business Can Operate During a Boil Water Notice

  1. Install a water treatment system that can kill waterborne bacteria and viruses. (UV water sterilizers).

  2. Purchase water and ice outside the boil water advisory area.

  3. Freeze food to kill bacteria. This EPA memo states that water in frozen food does not pose a risk if the food has been frozen for 7+ days at 5-14 degrees Fahrenheit or for 24 hours at -4 degrees Fahrenheit.

  4. Boil water for 2 minutes to kill potential bacteria.

UV sterilizers remove viruses and bacteria from water

How to Ensure Food Handling Equipment is Safe After a Boil Water Notice is Lifted

What does a restaurant, school, food processor or any business in the food handling industry need to do when a boil water order is lifted?

All equipment that processes or uses water should be thoroughly cleaned and sanitized.

Here are three suggestions on steps to take:

1. Clean Out and Sanitize

Disinfect all food handling equipment that uses water.

    • Clean out and sanitize coffee machines
    • Clean out and sanitize soda fountains
    • Clean out and sanitize ice machines
    • If you own a reverse osmosis or other filtration equipment, sanitize the system. When cleaning and sanitizing this equipment, owner's manual care instructions should be carefully followed.
    • Sanitize water coolers as water coolers generally operate on reverse osmosis (RO) technology and RO systems cannot filter or treat waterborne virus, bacteria and other microbiological contaminants.

2. Wash Dishes and Counters

Manually wash, rinse and sanitize dishes from an approved water source or boiled tap water. Sanitize all food-contact surfaces.

3. Prepare for Future Use

Once your kitchen is sanitized, make sure all water used in food preparation has been purified. Provide bottled or treated drinking water for customers going forward. Consider installing a UV water sterilizer system at the incoming water line to your restaurant. UV water disinfection systems are relatively inexpensive (starting at ~CA$986.98) and protect bacteria or virus-contaminated water from entering your restaurant.


Restaurant Water Treatment Solutions During a Boil Water Order

If a restaurant or business does not have a way to effectively treat water, they may have to temporarily shut down, at great monetary loss, until the water issue is resolved.

So how does a business continue to operate? There are several effective methods for general water treatment and filtration. But standard water treatment equipment, such as ion exchange and reverse osmosis, cannot protect against waterborne bacteria and virus which are customarily the culprits in a water boil advisory.

Ultraviolet (UV) water purification systems are widely considered to be the most effective method to ensure the destruction of harmful waterborne bacteria and microbes during a boil water order.

In simple terms, UV technology can destroy 99.99% of harmful microorganisms (including E. coli and coliform bacteria) without the use of heat or chemicals, and can purify hundreds of gallons of water per minute.

UV systems are available in a variety of sizes and for several applications including residential and commercial.

UV systems are safe, simple to install, small footprint, require very little energy, and are easy to maintain. For a business, the ROI on installing UV equipment could potentially be realized during one boil water advisory. Millions of businesses and households use UV technology to provide clean drinking water every day.

Be prepared for the next boil water advisory. Eliminate risk: ultraviolet sterilizers are engineered to give you peace of mind.
