When might a Boil Water Advisory be issued?

Water line breaks and repairs are the most common reason for issuing a Boil Water Advisory. Other circumstances that warrant an advisory include:

  • Complications with the water treatment process
  • Loss of pressure in a significant portion of the distribution system
  • Prior to a hurricane making landfall



When is a Repeal issued?

After the break is repaired, the water system undergoes extensive bacteriological testing before the drinking water advisory is repealed.



What are the current Advisories and Repeals?

All active Boil Water Advisories and all Repeals from inactive Boil Water Advisories can be found on the City of Columbia Water & Sewer Nixle Page.



What is a Boil Water Notice and why would one be issued?

Boil Water Advisories are issued when there is a POTENTIAL contamination.

Boil Water Notices are only issued when there is a CONFIRMED contamination. Please see the Boil Water vs. Advisory Notice PDF document for more information.
