Kelowna Sewer Backup and Basement Flood Response Guide

Which professionals should handle plumbing, electricity, cleanup, and restoration?

1Keep people and pets out and assess electrical danger without entering affected water.
2Notify the insurer and call a plumber for the private building sewer.
3Use the City reporting route if the plumber cannot resolve the blockage and suspects the main.
4Document conditions and coordinate qualified contamination cleanup, electrical assessment, drying, and restoration.

What should you do before entering a sewage-contaminated basement?

Treat sewage and standing water as contamination and assume electrical equipment may be unsafe until assessed. Keep occupants and pets away, avoid contact, photograph conditions from a safe location, notify the insurer, and use emergency services when there is an immediate threat. Do not mix bleach with other cleaners.

Do not step into water when outlets, appliances, panels, wiring, or other energized equipment may be affected.
Avoid spreading contamination through footwear, tools, laundry, toys, or materials moved into clean rooms.
Record the time, affected rooms, water depth, visible source, odour, utility conditions, and calls made before removal begins.

Who is responsible for the private sewer and the City main?

Kelowna distinguishes the privately maintained building sewer from the City-maintained sewer main. Start with a plumber for the private line. If the plumber cannot clear the blockage and evidence points to the main, use the City's current sewer-issue reporting channel. Reporting does not establish liability or payment responsibility.

Ask the plumber to document where the blockage was found, what was attempted, and why City escalation is recommended.
Use the live City channel for current business-hours and after-hours routing rather than saving an evergreen phone number here.

What should you document before damaged material is removed?

Photograph rooms, contents, finishes, equipment, water lines, and the apparent path before qualified cleanup begins. Keep invoices, plumber findings, City reference numbers, insurer instructions, disposal records, moisture or electrical assessments, and restoration scopes. A source record supports decisions but does not guarantee insurance coverage or City liability.

What else should you ask after a sewer backup?

Should you enter a basement containing sewage and standing water?

Not when electrical safety is uncertain or contact cannot be avoided. Keep people and pets out, use emergency help for immediate danger, and have the affected electrical and contaminated areas assessed before entry or cleanup.

When should a blocked sewer be reported to the City of Kelowna?

Start with a plumber for the private building sewer. If the plumber cannot clear it and has reason to suspect the City main, use Kelowna's current sewer-issue channel and retain the plumber's findings.

Can sewage-contaminated drywall or flooring always be cleaned?

No. Material decisions depend on contamination, porosity, exposure, drying, and qualified assessment. Follow current health guidance and do not assume a finish is salvageable because its surface looks dry.

Should bleach be mixed with another cleaner for disinfection?

No. Interior Health warns not to mix bleach with other cleaners. Cleanup methods and concentrations depend on the material and conditions, so use current health guidance and qualified help.

Does the City or insurer automatically pay for the damage?

No. Report the incident, preserve evidence, and follow the insurer's instructions, but do not treat notification, a sewer location, or a City service request as a decision about liability or coverage.
