Planting trees can enhance your yard, provide shade, and boost property value, but some species can wreak havoc on your sewer lines. Tree roots naturally seek out water and nutrients, making sewer lines a prime target if the wrong trees are planted nearby. According to Trenchless Solutions in Pleasant Hill, CA, thoughtful tree selection and placement can save homeowners from significant plumbing issues.
Why Tree Roots and Sewer Lines Don’t Mix
Tree roots are drawn to the moisture and nutrients often found in sewer pipes. Over time, roots can infiltrate small cracks or joints in the pipes, causing blockages or severe damage. This is especially common with older clay pipes, which are more susceptible to root intrusion than modern PVC materials.
Best Trees to Plant Near Sewer Lines
When planting trees near sewer lines, it’s best to choose species with less aggressive root systems. Here are a few tree options that are considered safer:
- Dogwood (Cornus species): These small ornamental trees have relatively shallow root systems that pose minimal risk to sewer lines.
- Japanese Maple (Acer palmatum): Known for their beauty and slow-growing roots, Japanese maples are a great choice for small yards.
- Serviceberry (Amelanchier species): These trees are drought-tolerant and have non-invasive roots, making them sewer-safe.
- Crape Myrtle (Lagerstroemia species): This popular tree stays small and doesn’t require deep rooting, reducing the risk to underground utilities.
- Redbud (Cercis canadensis): A native species with manageable roots that rarely cause pipe damage.
Trees to Avoid Planting Near Sewer Lines
Some trees have aggressive roots that can extend far beyond the canopy, seeking water sources like sewer lines. Avoid these species:
- Willows (Salix species): Known for their water-seeking roots, willows can easily invade pipes.
- Silver Maple (Acer saccharinum): This fast-growing tree has an extensive and invasive root system.
- Poplar (Populus species): These trees are notorious for their aggressive roots and are best planted far from any underground utilities.
- Oak (Quercus species): While majestic, oaks have extensive root systems that can damage pipes if planted too close.
Tips for Safe Planting
To minimize the risk of tree roots invading sewer lines, follow these tips:
- Know Your Sewer Line Location: Before planting, locate your sewer lines using local utility services or a professional.
- Maintain Safe Distances: Plant trees at least 10-20 feet away from sewer lines. Larger trees with more extensive root systems may require even more distance.
- Install Root Barriers: Use barriers to direct root growth away from sewer lines. These can be physical barriers or chemical treatments applied during planting.
- Choose Smaller Trees: Opt for trees that grow to a mature height of less than 20 feet to reduce the risk of root intrusion.
