GAS EMERGENCIES

CUSTOMER SERVICE

Trees growing near power lines can be dangerous. Unitil schedules tree pruning in your area every five years. We use industry best management practices and techniques that minimize disease and decay entry points. One of these techniques, directional pruning, directs tree growth away from wires. This pruning practice was developed in conjunction with the U.S. Forest Service and is endorsed by the International Society of Arboriculture, the National Arbor Day Foundation and other tree-care professionals around the world.

 

Directional Pruning

The following illustrations are examples of the proper directional pruning for shade and ornamental trees. Click here to learn more.

Side Pruning
Side Pruning
We strive to trim vegetation to approx. 10 feet back from electrical wire. This pruning is conducted pole to pole.

Overhead Pruning
Overhead Pruning
Typically we trim 15 feet above the wires on top of the poles. Greater clearance may be required depending upon tree species and location.

Ground cut pruning
Ground Cut
Ground cutting includes the removal of small trees and brush 8 inches in diameter or less for species with the capacity to grow into the wires.

Under Pruning
Under Pruning
We cut along the ground to remove small trees. For larger trees, we keep a four-foot radius below and around the lowest wire attachment by pruning and removing deadwood or hazardous branches.

 

Distribution Lines

Distribution vegetation management is systematic removal of vegetation growth and damaged or defective limbs along distribution circuits, along roadways and driveways. Using a bucket truck, operated by line-clearance certified contractors, we remove limbs, branches and trees that are in danger of coming in contact with power lines and poles. You'll be notified of upcoming work before we start.

During cycle pruning, we sometimes identify trees on your property that need removal. We'll notify you if action is necessary. You're welcome to discuss it with us further.

Sub-Transmission Lines

Transmission vegetation management refers to maintenance of Unitil's rights-of-way. The transmission system is the "backbone" of our electric system. Tree and limb contact must be completely eliminated on these lines to ensure continuous service.

Right-of-Way Vegetation Zones

Right-of-Way Vegetation Zones

 

The company’s right-of-way maintenance program is based on Integrated Vegetation Management (IVM) principles and practices.  IVM is defined as a system of managing plant communities by which vegetation managers identify compatible and incompatible vegetation, consider action thresholds, evaluate control methods, and select and implement controls to achieve specific objectives.
