Understanding Sewer Backup Incidents

Sewer backups are an unfortunate but common issue in many communities.

While municipalities work hard to prevent them, they can still occur. This guide will help property owners and residents understand why backups happen, how to prevent them, and what steps to take if one affects your property.

 

What Causes a Sewer Backup?

Sewer overflows can result from several factors, including:

• Blockages in sewer pipes, whether in main lines or service laterals (the pipes connecting buildings to the main line).
• Tree roots, which can invade pipes and cause cracks or blockages.
• Aging infrastructure, where older pipes deteriorate over time.
• Insufficient capacity, due to residential or commercial growth.
• Construction mishaps, where work near sewer lines damages pipes.
• Household waste buildup, including grease, hair, diapers, sanitary products, and other debris that shouldn't go down drains.

How Could a Sewer Backup Affect My Home?

If a backup occurs in a city-maintained sewer line, wastewater usually overflows through the nearest manhole. However, in homes with basements or lower-level drains, sewage may back up through toilets, sinks, or floor drains.

What Should I Do If Sewage Backs Up Into My Home?

Take immediate steps to protect people and property:

Seal drains and toilets – Use stoppers, plugs, or weighted covers. A string mop can help block toilet openings.

Stop running water – Avoid using sinks, toilets, and drains until the issue is resolved.

Check with neighbors – If others are experiencing the same issue, the problem may be widespread.

Call the city’s Public Works Department – Their contact information is listed at the end of this guide.

Call a plumber – If the issue is within your home’s lateral line, a plumber can diagnose and fix the problem.

What Will the City Do If I Report a Backup?

When you contact the city, they will:

1. Gather information about the backup, such as timing, location, and extent of the issue.
2. Inspect the main sewer line for blockages. If found, they will clear the blockage immediately.
3. If no blockage is found in the city’s main line, they will advise you to contact a plumber, as maintaining the lateral line is the property owner's responsibility.
4. Offer guidance on minimizing damage and cleanup options if the backup resulted from a city sewer line issue.

What Does the City Do to Prevent Sewer Backups?

Regular maintenance – City crews inspect and clean wastewater lines on a routine schedule.

Use of degreasing agents – In problem areas, the city applies chemicals to break down grease.

System design – Sewer lines are designed to minimize blockages.

Ongoing monitoring – Despite these efforts, backups can still occur, usually within pipelines rather than inside homes.

How Can I Prevent Sewer Backups?

Properly dispose of grease – Never pour grease down the drain, as it can solidify and cause blockages.

Avoid flushing non-biodegradable items – Diapers, sanitary products, and paper towels can clog pipes.

Be mindful of tree roots – If your home has older, jointed pipes, tree roots may invade them. Consider having your lateral line inspected.

Install a backflow valve – If your home has a basement or other below-ground drains, a backflow valve can help prevent sewage from entering.

Consult a plumber – They can provide additional preventive measures specific to your home.

Will Insurance Cover Sewer Backup Damage?

Most standard homeowner’s or renter’s insurance policies do not cover sewer backup damage unless you add a special rider. This additional coverage is typically affordable but must be specifically requested. Contact your insurance provider to ensure you are protected, especially if you have below-ground living spaces. Like most municipalities, the city is not responsible for damages resulting from sewer backups, as many incidents occur due to factors beyond its control.
