The following issues may arise if trees are planted close to a septic tank and drain field:

Damage to roots

Tree and shrub roots may move in search of water and nutrients toward the septic tank and drain field. If the roots get inside the tank or drain field, they may harm the structure by breaking or blocking the pipes or by shifting or settling the tank or drain field.

System overloading

Tree and shrub roots have the capacity to absorb a sizable amount of water, which might raise the demand for the septic system and result in an overload. This may result in system issues like backups and overflows.

Treatment interference

As they can absorb some of the wastewater that is meant to be filtered by the soil, the roots of trees and shrubs might obstruct the treatment process in the septic tank and drain field. This can result in issues and lessen the system’s effectiveness.

It is typically advised against planting trees and shrubs within at least 20 feet of the septic tank and drain field in order to prevent these issues.

If there are already trees or bushes, it is crucial to routinely check on them and get rid of any potential problem roots.
