Who Is Responsible for Sewer Line Repair?

If you’ve had issues with your plumbing and sewer lines, you’re probably wondering where the responsibility for the sewer or plumbing issue belongs with your city or municipality. When your pipes back up, it may be because you have clogs in the drains in your home – or it may be due to larger clogs in the main sewer lines.

Who is responsible for the sewer line repair when things go wrong? It depends on where, exactly, the plumbing issue originates. Our guide will help you understand what to expect in the event of a necessary plumbing repair.

What Causes Sewer Backups?

Some common causes of sewer backups include:

  • Clogs: Your sewer lines can become blocked if you flush things you shouldn’t. It also can happen naturally over time, with debris building up on the inside of the pipe. 
  • Tree roots: Mother Nature damages sewer lines when tree roots grow through the pipes. This situation damages the pipe and often causes clogs as waste gets caught in the roots. 
  • Old age: Old sewer pipes may deteriorate, which causes them to collapse or break. 
  • Damage: Newer pipes can also be damaged and cause backups. This might happen if the ground shifts or if the pipe gets hit by construction equipment while you’re renovating. 
  • Main sewer line issues: When the main sewer line has issues, such as a clog, damage or an excessive amount of water from heavy rainfall, it could create a sewer backup.

Your Sewer System – A Primer

Part of understanding when and where you’re responsible for handling plumbing repair to the sewer lines and when removing the clogs or performing repairs falls on the city involves a little rudimentary knowledge of the sewer pipe system itself.

The Main Line

The main sewer line takes the wastewater from several houses and carries it to the municipal wastewater treatment plant. Any issues with the main line itself are the city’s responsibility, including removing clogs and fixing burst pipes. The sewer main is located just outside the boundaries of the property owners in the area.

Determining where the problem may be yours may benefit from a current property survey. Knowing exactly where your property lines are and where they are concerning the city sewer main may go a long way towards determining what, if any, responsibility for plumbing repair lies.

Your Sewer Lines

If the sewer issues stem from pipes that run off the main line, especially if it’s clearly on your property, plumbing repair becomes your responsibility. In these cases, it’s generally attributed to a plumbing “user error” on your part, such as flushing stuff that shouldn’t be flushed (only waste and toilet paper, please) or pouring cooking grease down the kitchen sink. There are other causes for sewer problems, but if it’s a problem with just your lines, and on your property, then you’re the one who shoulders the financial responsibility.

There are two types of pipes that run from the house to the main sewer line, the upper laterals and the lower laterals. The upper lateral carries the sewer waste from your house, both, the cleanout from the building, and the rest of your property line. It then joins the lower lateral beneath the street. The lower lateral runs from the boundary of your property line to the main sewer line. While this section of the sewer pipe technically isn’t on your property, you may still be responsible for damage to this area, especially if the damage is due to clogs in the pipes or from tree root systems exerting pressure on the pipes and joining seams.

When Sewer Repairs Are Your Responsibility

Sewer repairs are your responsibility if:

  • The issue is with the upper sewer lines that carry waste from your property to the pipes in the street
  • The issue is with the lower laterals, which collect waste and transport it to the main sewer
  • The main sewer line on your property has been damaged by something within your control

So, if you’ve flushed non-degradable wipes down the toilet and clogged your own pipes, that’s your job to fix. It may also be your job to fix the main sewer line if you’ve been digging up your driveway and damaged it, even though that pipe isn’t your property.

Will My Insurance Cover Sewer Line Repair?

When you choose a homeowner’s insurance policy or renter’s policy, check your coverage for sewer line repairs. In some cases, an insurance adjuster may ask how the problem was caused – did you flush too many baby wipes and feminine hygiene products down the commodes, for example. In other cases, the problem may be covered if the cause is determined to be from an outside agency.

It’s always best to discuss the financial responsibility for common problems before taking out an insurance policy. If you’re renting, check your lease for plumbing responsibility, and if it looks like you’re responsible for some of it, ask for a renter’s insurance policy that covers unexpected emergencies.

How to Prevent Sewer Line Issues

You can take steps to keep your sewer lines in good shape, including:

  • Watch what you flush. Avoid flushing anything other than waste and toilet paper.
  • Protect drains. Keep grease, food particles and other items from going down kitchen and bathroom drains.
  • Schedule an inspection. At Bluefrog, we offer video inspections to see what’s going on underground. We can spot early issues before they cause a backup.
  • Clean the lines. While we’re there, we can hydrojet your lines to clear any buildup in the pipes.

When Sewer Repairs Are the City’s Responsibility

The main sewer line belongs to the city, and it’s their job to complete most repairs. Therefore, you won’t usually need to pay for:

  • Repairing a leaking main sewer line
  • Clearing a blocked main sewer line caused by other users
  • Ongoing maintenance of that sewer line

In some cases, if a main sewer line issue causes damage to your home, you may be able to get the city to cover the cost of that repair.

Note that there are some exceptions to the above. If the sewer line is on your property and the damage was caused by tree root incursion or other things you could have prevented, the city might demand you pay for the work.

Bottom Line

Even if your plumbing seems to run smoothly, you should know who’s responsible when it doesn’t. In most cases, the homeowner is responsible for the sewer line from the house to the street. But even when the city sewer line is clogged, the repair costs could be assigned to you, depending on what, exactly, caused them.

Sewer clogs and the resulting plumbing repair can be expensive. It’s important to understand what your responsibilities are, when homeowner’s insurance covers the bill and, if you’re a tenant, whether it’s yours or the landlord’s responsibility to fix problems. Luckily, the team at your local bluefrog Plumbing + Drain is here to help – even for after-hours emergencies.

Frequently Asked Questions

Who Is Responsible for the Sewer Line Under the Street?

The responsibility for the sewer line under the street falls to the city. Anything beyond your lower lateral pipeline belongs to the city, and it’s their job to clear blockages or repair leaks in those pipes.

Who Is Responsible for Blocked Drains Outside?

If there’s a blocked drain outside of your home, who is responsible depends on whether the blockage is in your lateral lines or the main line. The lateral line is your responsibility, but the main line belongs to the city.

Who Is Responsible for Sewer Lines on My Property?

You are responsible for the cleaning and maintenance of sewer lines on your property up to the point where they connect to the city’s main sewer line.
