Boil water notice

EWEB will issue a boil water notice when the utility believes water quality is, or may be, compromised.

A variety of circumstances can trigger such a notice, including a main break, a drop in water pressure, a natural disaster or vandalism.

After a trigger event has occurred, EWEB will immediately issue a notice as a precautionary measure, as required by law, to help protect the health of our customer-owners. EWEB will then conduct laboratory testing to confirm whether or not water quality has, in fact, been comprised. This testing typically takes one day. If was no actual contamination is present, the boil water notice will be discontinued.

When to use disinfected water: Quick household guide

When a boil water notice is in effect do not use water from any appliance connected to your water lines. This includes water and ice dispensers in your refrigerator/freezer.

Your household may choose to use water from an emergency water supply container that has been stored in your home or purchase bottled water. However, if tap water is still flowing, disinfecting your tap water may be a more convenient option.

To disinfect water by boiling, it should be brought to a rolling boil for at least one minute. If the power is out you can disinfect water using unscented bleach. Download a printable version of instructions for water disinfection.

See the following table for a quick-reference guide provided by the Oregon Health Authority about which household activities require safe, disinfected water. Download a printable version of when to use disinfected water.
