Your septic system helps remove and dispose of wastewater
from your home. However, many things can hinder the functionality and
durability of your septic system. Trees are one of the things that can affect
your septic system. Here is what you need to know about trees and your septic
system.
How Do Trees Affect the Septic System?
Trees can adversely impact septic systems due to their
extensive root systems that actively seek out water sources. These root systems
often infiltrate and encroach upon septic system components, leading to many
problems.
Firstly, tree roots can clog and obstruct septic system
pipes. As trees grow, their roots naturally expand and can penetrate the small
openings or cracks in pipes. This intrusion can cause blockages, restricting
the flow of wastewater from the household to the septic tank and, in severe
cases, lead to backups inside the home.
Secondly, tree roots near the septic tank can undermine its
structural integrity. Tree roots seek out sources of moisture, and if they
infiltrate the tank, they can cause cracks or fissures in the concrete or other
materials. Over time, this damage may lead to leaks, risking contamination of
the surrounding soil and groundwater.
Additionally, tree roots may interfere with the drainage or
leach fields, which are responsible for filtering and dispersing the effluent
from the septic tank. As roots grow within this area, they can create
blockages, reduce the system's ability to treat wastewater effectively, and
cause the field to become less efficient in absorbing and treating it.
Furthermore, tree roots can absorb significant water from
the soil surrounding the septic system. This excessive water uptake can dry out
the soil, diminishing its capacity to naturally filter and purify the effluent
before it reaches the groundwater, potentially leading to pollution.
Which Trees Can't You Plant Near the Septic System?
Certain trees should not be planted near septic systems due
to their extensive root systems and aggressive water-seeking behavior. These
trees can damage septic system components, causing costly and troublesome
repairs. Aggressive species like willows, poplars, and silver maples are
problematic because their roots can infiltrate and clog septic pipes and drain
fields.
Furthermore, large trees like oaks and pines with
deep-rooting tendencies can disrupt the integrity of the septic tank and
drainage lines, leading to leaks and system failure.
Which Trees Can You Plant Near Septic Systems?
When considering trees to plant near septic systems, it is
crucial to prioritize species with non-invasive root systems. Opt for trees
with shallow, spreading root structures, as they are less likely to interfere
with pipes or leach fields.
Choosing smaller-sized trees is also prudent, as they are
less likely to cause damage than larger, more established trees with extensive
root systems. Additionally, fast-growing trees should be avoided since their
roots tend to spread rapidly.
Ideal tree options include ornamental varieties like
dogwood, Japanese maple, and redbud, which offer aesthetic appeal without
posing significant root-related threats. Alternatively, fruit trees like apple
or cherry can be planted, provided they are dwarf or semi-dwarf varieties, as
these typically have less aggressive root systems.
What Are the Best Practices for Planting Trees Near
Septic Systems?
Before planting, locate the septic system's components,
such as the tank, drain field, and distribution box. Maintain a safe distance
between the trees and these elements; a minimum of 10 to 20 feet is usually
recommended. This distance allows the trees to flourish while minimizing any
risk of root intrusion.
Proper watering and mulching can promote healthy root
development without causing septic system issues. Also, avoid planting large
quantities of trees nearby, as a concentrated root system can pose a greater
threat.
