When is the City Responsible for Sewer Lines?

August 4, 2020 | Blog

Sewer line repairs and replacements are no small job, and they can cost a lot of money. That’s why it’s important to know who is responsible for footing the bill in the event of a sewer problem. Here’s an outline to help you determine whether you or the city is responsible for sewer line issues.

Main Sewer Lines

The city is responsible for any sewer problem starting from the main sewer line. This line carries waste from your home and surrounding homes to places like the city’s treatment plant. The pipe usually sits outside your property line on public property.


The lateral lines are the pipes that run directly from your home to connect to the main sewer line. There are two lateral pipes, the upper and lower lateral lines.

The upper lateral runs from your house to your property line, which ends at the curb or sidewalk. The lower lateral stems off from this to connect the upper lateral to the main line. Even though the lower lateral isn’t on your property, it still falls under your responsibility

Urban vs. Rural

If you live in a rural community where there is no municipal sewer system, you are responsible for all issues with your home’s septic system. In an urban community, the city will be responsible for sewer line repairs that fall outside of your property line, with the exception of the lower lateral line.


Depending on the coverage of your homeowner’s policy, your insurance may be able to help with the cost. If you find a problem in the sewer lines that you are responsible for and don’t know if the damage is covered by your insurance, check with your provider.

Very Knowledgeable

I recently had several plumbing leaks repaired and couldn’t be happier with the prompt service I received from Parker and Sons. They are very knowledgeable, friendly, reasonably priced, and do quality work. I would definitely recommend them to my family and everyone. I would trust them to repair any leak in the house.

Amazing Service!!!

Amazing service!!! Called and came the same day within 2 hrs. Our toilet had to be re-fitted and snaked. They did a beautiful job on the re-fitting and got the large piece of plastic out of the toilet. Will definitely be recommending them to friends and family. Great service, great people, hard to find these days!!!

Shakira C.

Excellent Service! We had some work done on our kitchen and Parker and Sons were able to come out to our house and help us with our remodel. Great guys and great service. I would recommend them to anyone needing a plumber service.

Brad B.

Great to Work With

Jim and his guys are great to work with. Had Parker & Sons come out to take a look at an AC unit at one of my rental properties. Unit is in the attic. Had to replace a coil on it and did a great job. Will definitely use again.

Jeff C.

Amazing Staff!

I have referred Parker and Sons to all of my customers and I would not think of referring anybody else. They have been great and very punctual. All of the plumbers and office staff have been amazing!

Miguel B.

Reasonable Prices

I was in good hands today with journeyman plumber Mark Rizley. He remained until all was better than before. He replaced a PRV and improved a mediocre repair recently done by another well known local company. The price remained reasonable despite the extra effort needed for the job. Well done Mark! Parker and Sons will be my first call in the future.

Todd D.

Fantastic Company!

This is a fantastic company with outstanding professionalism, quality of work, and customer service. While their prices are extremely competitive, their work doesn’t feel cheap like some of the companies you can hire of off Craigslist or on a FB yard sale page. This is a reputable company with proven work and licensed, skilled technicians.

Fair Prices & Excellent Work

Have used Parker & Sons 3 different times, once for a huge complex plumbing repair and twice for smaller jobs. Fair prices and excellent work/fast response time every time.
