How do I fix a sewer under a tree?

Fixing sewers that run under trees with minimal disturbance

A $70,000 tree may shock some, but to our client who just had a fully mature tree delivered and planted, it was the cherry-on-top to complete his dream lawn. His joy was short-lived. A stormwater pipe that ran beneath the tree started having problems draining and began to back up into his yard. The first plumber he called said the tree had to be torn out for pipe access. We disagreed. In our experience, 9 times out of 10, there is a way to fix the plumbing and spare the tree. In our client’s case, we were able to reroute the pipe around the perimeter of the new tree’s drip edge so as not to disturb the tree.

Do you have to tear down a tree to fix a sewer that runs beneath it? If your sewer runs under a tree, how can you use preventative maintenance to keep issues at bay? Before planting a new tree on your lawn, how can you be sure it won’t affect your sewer? As nature enthusiasts and plumbing experts, we’re happy to answer these questions.

What problems can trees make for sewer lines?

Sewer lines that run below a tree tend to become damaged more than those that do not, simply because of the tree’s roots. Tree roots seek out moisture and nutrients. In older sewer lines, the joints between sections of pipe degrade.  

Terracotta pipe joints are sealed with concrete. Concrete cracks as it ages and roots sense the moisture and “nutrients” flowing through your sewer.

If there is even the smallest crack in a sewer pipe’s joint, tree roots work their way in. The tree grows big and healthy, thriving off the nutrients in the wastewater flowing through the pipe. Root intrusion in sewer lines creates clogs. In turn, clogs create backups. Sewer backups render your bathroom unusable.

Repair the sewer and spare the tree

If your sewer runs under your tree, don’t fret. There is almost always a way to avoid cutting down a tree. It all depends on where your sewer line is located in proximity to the tree.

Before C.A. Taciak & Sons does any sewer repair where a tree is in harm’s way, we create a plan of attack. We use pipe locating techniques to determine:

Is the sewer directly under the tree or just under the roots/drip edge of the tree?

How much fall is available in the sewer line to work with? Is there enough drop between the house and the street connection for the sewer to be rerouted outside of the most efficient pathway?

The farther the sewer is to the side of the tree’s drip edge, the more options there are to repair or replace the sewer.  If the sewer line runs directly under the center of the tree, a trenchless sewer repair may be necessary.

Trenchless sewer repair saves landscaping

Depending upon your level of investment, trenchless pipe repair – such as pipe bursting, pipe lining, or pipe patch – is a great option to avoid cutting down a tree.

Trenchless pipe repair is more expensive than conventional sewer repair. It is less expensive than tree removal, stump grinding, sewer replacement, and a new tree.

If you call Baltimore home, you know that a tree in the city is a rare sight. A client of ours who lives in a lovely Charles Village townhome has a 50ft mature tree growing in her backyard. Unfortunately, her sewer exits her home in the rear and runs directly under the tree. She called us for a second opinion when she was told the only way to repair her sewer involved cutting down the tree. We were happy to be able to use pipe bursting and surgical sewer repair methods to replace the sewer line underneath the tree without disturbing the tree or its roots.

Keep your tree and your sewer in your home maintenance plans

If you have a tree that you love, you should consider the possibility that your sewer line runs under it.

How can you know for sure? A video pipe inspection and pipe locate are a great place to start. This is also a good first step if you are considering adding a tree to your property. Working in conjunction with your plumber and landscape designer, you can map the route of your sewer line, completely avoiding potential headaches in the future.

There are many more options for sewer maintenance than there are for emergency sewer replacements. We encourage you to think about your trees and sewer before either becomes an issue.  It’s great to have a quality contractor on your side who understands the value of your horticulture and your home.
