What is a boil water advisory?

Oct 10, 2019

What is a Boil Water Advisory?
A Boil Water Advisory is a public health recommendation from Carolina Water Service, Inc. of North Carolina (CWSNC) advising customers to boil their tap water before using it. This is in response to an event that could have allowed contaminants to enter the water distribution system. Because the water quality is unknown, customers should assume the water is unsafe to drink and take the necessary precautions listed below.

When does CWSNC issue a Boil Water Advisory?
Typically, we issue a Boil Water Advisory after a water main break repair, small or widespread loss of pressure in our water system, or a natural disaster.

In some cases, our crews can repair a water main while maintaining adequate pressure to prevent contamination from entering the water distribution system. (When we do a repair in this way, no Boil Water Advisory is needed.)

When we issue a Boil Water Advisory, we notify only the customers affected. If the risk of contamination is widespread, CWSNC will put information on our website,  notify customers using our My Utility Connect application, social media, etc. to inform the public.

How long will a Boil Water Advisory be in effect?
An advisory will remain in effect until bacteriological test samples show the water is safe to drink. Bacteriological testing typically takes 24 to 28 hours to complete.

What should I do during a Boil Water Advisory?
Boil tap water before using it for drinking, making ice, washing dishes, brushing teeth or preparing food. Bring tap water to a rolling boil for at least 1 minute and let it cool.

Should I use my coffee maker, water or ice dispenser when a boil water advisory is in effect?
During an advisory, do not use water from any appliance connected to your water lines. This includes water and ice dispensers in your refrigerator/freezer. Use boiled or bottled water to make coffee and ice.

How should I wash dishes during a Boil Water Advisory?
Household dishwashers are generally safe to use if the water reaches a final rinse temperature of at least 150 degrees Fahrenheit or if the dishwasher has a sanitizing cycle.

To wash dishes by hand:
Use boiled water; or wash and rinse dishes as normal. Then in a separate basin, add 1 teaspoon of unscented household bleach for each gallon of warm water. Soak dishes in basin for a least 1 minute. Let dishes air dry completely.

Should I bathe or shower during a Boil Water Advisory?
It is safe to bath or shower, but be careful not to swallow any water. Use caution when bathing babies and young children. Consider giving them a sponge bath to reduce the chance of them swallowing water.

Can I wash my hands during a boil water advisory?
Yes, vigorous handwashing with soap and your tap water is safe for basic personal hygiene. However, if you are washing your hands to prepare food, you should use boiled (then cooled) water, disinfected or bottled water with hand washing soap.

What if I drank some of the water before I found out about the advisory?
This advisory was issued as a precaution, so your risk of getting sick is very low. However, if you begin to have a fever, diarrhea, or nausea you should seek medical attention.

How will I know when the advisory or notice has been lifted?
CWSNC will rescind the Boil Water Advisory when the results from the testing have been confirmed that the water is safe to drink. You will receive your notification the same way you were informed of the advisory.

Is a Boil Water ADVISORY the same as a Boil Water NOTICE? NO!
We issue a Boil Water Advisory when water contamination is possible. In an advisory, we recommend that affected customers boil CWSNC water before consumption or use bottled water. A Boil Water Advisory is voluntarily issued when water contamination is possible.We provide the notification as a courtesy to keep our customers safe just in case.  During an advisory we recommend that customers vigorously boil water for at least 1 minute before consumption or drink bottled water.

We issue a Boil Water Notice when contamination is confirmed in the water system. During a notice, affected customers must boil their water before consumption or use bottled water. A Boil Water Notice is required by law to be issued when contamination is confirmed in the water system. During a notice, affected customers must boil water before consumption or use bottled water.

If you have any questions, call our Customer Service Department at 800) 525-7990.

Hurricane Season 2019: Be safe and be prepared

Jul 15, 2019

Hurricane Safety FAQs:

Education is the best protection against the dangers of a hurricane. Make a disaster plan with your family, put together a basic supply kit, and prepare your home and property before a warning is issued. Know the warning signs of hazardous tropical storms, how to obtain emergency alerts, and where to evacuate or seek shelter.

When is hurricane season?

  • Hurricane season begins June 1st and goes up until November 30th. Peak season runs from late August through September.

When should I start to prepare my home and family for a hurricane?

  • The time to start is BEFORE a watch or warning is issued for your area. Hurricane Awareness Week, which occurs in late May before the season starts, is the perfect time to create an emergency family plan or reassess the one you have. Go through your emergency supply kit and replace items that are missing or broken; update your phone with current emergency contacts and family phone numbers. Test flashlights and battery-operated equipment. Make sure your shutters are in working order and you remember how to put them up!

What should I do when a hurricane watch or warning is posted?

  • When a watch is issued for your area: double check your supplies, your shutters, and your plans. Get cash out from the bank and put gas in your car. Listen to local area radio, NOAA radio or TV stations for updates. Know possible evacuation routes and destinations.
  • When a warning is issued for your area: before the winds get too high, put up your shutters and prepare your yard (and pool if you have one). Lower the temperature of your refrigerator and fill your bathtub and extra jugs with clean water. If you need to evacuate, prepare your property quickly then leave the area with plenty of time. Traffic will pick up immediately once the warning is issued.

Where can I find an index of hurricane shelters in my area?

What do I need for a basic emergency supply kit?

The following items are recommended:

  • Water (one gallon of water per person per day for at least 3 days)
  • Food (a three-day supply of non-perishable food)
  • Battery-powered or hand crank radio
  • Flashlight
  • First aid kit
  • Extra batteries
  • Whistle to signal for help
  • Moist towelettes, garbage bags and plastic ties for personal sanitation
  • Dust mask to help filter contaminated air
  • Plastic sheeting and duct tape to shelter-in-place
  • Wrench or pliers to turn off utilities
  • Manual can opener
  • Local maps
  • Cell phone with chargers and a backup battery

How can I preserve clean drinking water during a storm?

  • According to the FDA, during and after a natural disaster, water may not be safe to drink. If your tap water cannot be used for drinking:
    • Use bottled water that has not been exposed to flood waters.
    • If bottled water is not available, boil your water to make it safe. Boiling your water will kill most disease-causing organisms. Boil it for one minute, let it cool, then store in a clean container with a cover.
    • If you're unable to boil water, you can disinfect it with household bleach. Add 1/8 teaspoon (about 8 drops) of unscented household (5.25% concentration) liquid bleach for each gallon of water, stir well, then let it sit for a half hour. Store in a clean container with a cover. 
    • If your property has a well that flooded, you'll need to test your water and disinfect it after the flood waters recede. 
How should I plan to keep my pets safe during a hurricane?

  • Assemble a hurricane readiness kit for your pet with essential items (food, water, a sturdy leash and a pet carrier if needed for transport).
  • Include a current photo of you with your pet in case you’re separated. Store medications and medical records in a waterproof container.
  • Know that many emergency shelters do not accept animals - find out ahead of time where you can stay with your pet if you need to evacuate your home. Prepare a list of friends, relatives, or boarding facilities where your pets could be cared for in an emergency.

Tips for Water Conservation

Jul 03, 2019

Tips for Water Conservation

Indoor tips:

  • Check water consumption on your monthly bills unexpected increases may result from undetected leaks.
  • Regularly check your faucets, spigots, toilets, water pipes, washing machine, and dishwasher for leaks.
  • Listen carefully for the sound of running water at night when no faucets or fixtures are in use.  Check for wet spots from the water meter to the residence indicating a possible underground water leak.
  • Toilets are one of the most common places for leaks.  Check flappers at the bottom of the tank or the fill valve malfunctioning.
  • Take shorter showers.
  • Don’t leave water running while brushing your teeth, shaving, etc.
  • When replacing used appliances check for waterless model toilets, hand and shutoff faucets and low-flow shower heads. Check the U.S. Environmental Protection Agency’s/Department Energy’s www.energystar.gov website for water and energy efficient models.
  • Know the location of the water shut-off valve for plumbing system so that you can turn off water quickly if you have a major leak.
  • Sensor shut-off devices can be used to detect a major leak in your plumbing system and turn off your water automatically even when no one is at home.

Outdoor tips:

  • Check outdoor spigots and hoses for leaks. 
  • Water lawns and plants before sunrise and after sunset.
  • Use hand-held spring loaded nozzles on lawn and garden hoses.
  • For irrigation systems, install automatic controls and rain sensors to prevent wasteful irrigation.
  • Rain or moisture sensors can be installed on irrigation system to prevent watering during or after rainfalls.
  • Choose drought-resistant, non-invasive plants for your lawn.
  • Use a soaker hose, bubbler, micro spray or drip irrigation system instead of the spray irrigation, which loses more water due to evaporation.
  • Purchase a rain barrel or install a cistern to reuse rainwater. (Rain barrels are available in your local region).
  • Use 2 to 4 inches of mulch around trees and shrubs to conserve moisture in the soil.
  • Consider drought tolerant groundcover, drought tolerant grass, or landscape with trees, shrubs and mulch.
  • Cut grass to a height of at least two inches (one inch for Bermuda grass) to encourage good root growth and to help shade and retain moisture in the soil.  Small grass clipping are good soil enhancers.


How to Find and Fix Pesky Household Leaks!

Mar 18, 2019

Did you know that an average household's plumbing leaks can account for nearly 10,000 gallons of water being wasted each year? This adds up to almost 1 trillion gallons of water being wasted annually nationwide! Easy-to-fix leaks around your house could be wasting 90 gallons of water or more, every day.

Fixing easily corrected water leaks can save homeowners about 10 percent on their water bills. So how do you know if your home hides costly and wasteful leaks? Here's a list of tips from the EPA.

1. Check your utility bill: Try examining your utility bill for January or February. It’s likely that a family of four has a serious leak problem if its winter water use exceeds 10,000 gallons (or 13.4 CCF) per month. You can also look for spikes - is your water use a lot higher this month than it was last month?

2. Read your water meter: Find your water meter, which is usually near the curb in front of your home but can be inside your home (e.g., in the basement) in cold climates. Use a screwdriver to remove the lid on your meter, which is heavy and usually marked “water.” Now that you’ve found the meter, take a reading during a period when no water is being used. If the meter does not read exactly the same after two hours, you probably have a leak.

3. Test your toilet: Put a few drops of food coloring into the tank at the back of your toilet and let it sit for 10 minutes. If the color shows up in your bowl, you have a leak. Make sure to flush afterward to avoid staining, and consider replacing your old toilet flapper if it is torn or worn.

4. Water world: Examine faucet gaskets and pipe fittings for any water on the outside of the pipe to check for surface leaks. Another telltale sign of a leak is decreased or inconsistent water pressure. If you notice a problem with your faucets, call a plumber.

5. Pipe problems: The pipes that deliver your water are a common source of leaks. If you own an older home, it is more likely to have plumbing problems. Replace galvanized pipes with plastic if possible, and insulate exposed pipes and those in the attic or basement if possible. Pipes can break or crack with age, pressure, or freezing.

Leaks are often easy to fix, requiring only a few tools and hardware that can pay for themselves in water savings. Adding new WaterSense labeled fixtures and other high-efficiency appliances will help further improve your home's water usage.


Protect your pipes! When in doubt, throw it out!

Feb 14, 2019

Oils and grease are wastes that our sewer system cannot handle and should not be discarded down the drain. Grease, fats, and oils will clog sewer lines (the same way bad cholesterol can clog heart arteries), causing sewage back-ups and flooding. Sewage back-ups can damage personal and our wastewater treatment system.

Carolina Water Service Inc., or North Carolina inspects and clears sewer pipes to prevent spills but we can't do this without your help. Drain excess grease or cooking oil into a can, cool and toss. Wipe any leftover grease from the pan with a paper towel and throw the paper towel away.

The same goes for our toilets. If you flush items down the toilet that don't belong there, you are inviting clogs and overflows. Even products labeled as "flushable" do not decompose in the sewer system and can contribute to clogging. Don't flush paper towels, baby wipes, adult or baby diapers, hair, cotton swabs, feminine products or dental floss. Only put toilet paper down the toilet.
