Trees and Your Sewer Line: What You Need To Know
Trees enhance property curb appeal, providing natural beauty and a relaxing atmosphere. However, it's important to consider their impact on sewer lines. Here is what you need to know about trees near sewer pipes.
How Tree Roots Can Affect Your Sewer Lines
Tree roots can damage your sewer line, leading to several noticeable signs. When roots penetrate the line, they create a blockage, causing gurgling sounds and restricted water flow in drains. Slow drainage in sinks and showers is another indicator, with tree roots being a common cause.
As roots continue to grow, changes in water flow and pressure become more apparent. Additionally, roots can trap waste, emitting unpleasant smells and causing backups through the drains. In severe cases, tree roots may create extensive pipe cracks, resulting in wet spots on the lawn. Toilet flushing problems—such as backups and waste lingering after flushing—can also indicate root-related sewer line blockages.
How to Plant Trees Near Sewer Lines
Careful planning and maintenance are crucial to avoid problems caused by tree roots near sewer lines. First, know the exact location of the sewer pipes by hiring a professional plumber. Once you have this information, you can plan your landscaping accordingly. Remember to plant trees at least ten feet away from drain pipes, regardless of the tree type.
If you choose trees with spreading root systems, maintain a distance of a hundred feet to prevent pipe damage. Regularly monitor and maintain the trees to prevent deep root growth and pipe damage. Avoid overplanting near sewer lines and consider alternative options like potted trees, hanging plants, baskets, trellises, or ground covers based on your needs.
Finally, select tree species that pose fewer risks to sewer lines, as some large trees can block or penetrate pipes, potentially requiring pipe relining. By following these tips, you can enjoy the benefits of trees without compromising your sewerage system.
Best Trees To Plant Near Sewer Pipes
When considering planting trees near sewage systems or water mains, it is important to exercise caution. Luckily, there are some secure alternatives available.
Here is a list of recommended hedges and statement trees that won't interfere with sewer pipes:
- Small apple trees can be planted a few meters away from the water line.
- Feijoa trees are another great option with non-invasive roots, excellent pest and disease resistance, and delicious fruit that falls when ripe. Planting a feijoa tree can eliminate blocked drains.
- The Coastal Golden Wattle, a native Australian shrub, grows to five meters in height and boasts beautiful golden yellow blooms in September.
- Azaleas are a simple yet lovely addition to any garden, offering a pink display without causing drain blockages. They can also be potted and placed around the house for a color-matching effect.
- Bay trees not only prevent drain clogs but also provide aesthetic appeal with their slow growth and deep green color.
Tree Species With the Most Invasive Roots
When renovating your lawn and planting trees, it's important to be aware of tree species with invasive roots that can damage underground sewer lines. Sycamore trees, willows, oak and fig trees, maple trees, aspen trees, elm trees, and birch trees are all known to be especially invasive.
However, this doesn't mean you have to avoid these trees altogether. Consulting with a plumbing or landscaping expert can help you understand the typical root length in relation to your pipe depth, type, and location.
