When water systems lose pressure there is an increased risk of contamination. Therefore, the WSSC Water recommends if you live in the affected area:
During a BWA
Boil water for drinking, making ice, washing dishes, brushing teeth and food preparation.
Water should be brought to a rolling boil for three minutes and cooled before using.
Water for pets should be boiled and then cooled for their use.
Dispose of ice from your refrigerator’s ice maker. DO NOT USE.
Disinfect dishes by washing them in dishwashing machines that have a dry cycle or a final rinse that exceeds 113 degrees F for 20 minutes, 122 degrees F for five minutes or 162 degrees F for one minute.
After the Boil Water Advisory is Lifted – Flush Your System
WSSC Water asks customers who were under the Boil Water Advisory need to take a few precautions.
Steps to Take
WSSC Water recommends running all cold water taps for five minutes.
If you have a single-lever faucet, set it to run the cold water.
Begin with the lowest faucet in your home or business and then open the other faucets one at a time, moving from your lowest floor to your highest.
After five minutes, turn off your faucets in reverse order, from highest to lowest.
You should also flush your refrigerator's water lines.
Customers and businesses should also dispose of any ice made since the precautionary Boil Water Advisory. The next three batches of ice should also be thrown out. Ice maker containers should be wiped clean with a solution of two tablespoons bleach to one gallon of water.
