What This Columbia Water Emergency Guide Covers
How to Report a Columbia SC Water Outage or No Water at Home
If your home suddenly has no water, very low pressure or a full-block water interruption, call Columbia Water Customer Care instead of waiting for a website update. A water outage can be caused by a broken main, emergency repairs, planned maintenance, a valve issue, a private plumbing issue or a service-area disruption.
Before calling, check whether the issue affects one faucet, the whole home or several homes nearby. If multiple neighbors are affected or there is water in the street, report it as a possible system problem.
Check whether the outage is inside or outside
Test more than one faucet. If only one fixture is affected, it may be a local plumbing issue. If the whole home has no water, call Customer Care.
Call Columbia Water Customer Care
Call 803-545-3300. Columbia Water lists this number as available 24 hours a day, 7 days a week.
Give outage details
Report the service address, nearest cross street, start time, whether neighbors are affected, water pressure level, visible leaks and any nearby construction or repair activity.
Check for advisories after service returns
If the outage involved line repairs or pressure loss, check the official Boil Water Advisories page and active advisory links for drinking water instructions.
Columbia Water-Line Break or Main Break: What to Do Immediately
A water-line break may show as water bubbling from pavement, water flowing down the street, sudden low pressure, no water, a sinkhole forming, muddy water, flooding near a curb or emergency utility work nearby.

Stay away from the break area
Do not walk, drive or let children play through flooded street water, sinking pavement, icy areas or water flowing around utility structures.

Watch official advisories
After a water-line break, check official Columbia Water safety pages for boil water advisory notices or active advisory updates.
