Choosing Between Underground or Overhead Power Lines

Choosing between underground or overhead power lines can be a difficult decision to make. In some areas, underground lines are now mandatory. But, in most areas, the choice is yours.

So, should you get overhead or overhead power lines? Underground lines are more aesthetically pleasing, and they remove the risk and dangers of low lines. However, installation does cost more. On the other hand, overhead lines are cheaper to install. But they are easily damaged and can be unsightly.

Ultimately, the decision will boil down to your unique situation. You will want to take into consideration the cost and likelihood of damage. If you live in an area that has a lot of trees, limbs will eventually break off and can hit the lines. Auto accidents are another factor for overhead power line damage.

In these situations, you will want to lean towards underground lines. If the area is prone to flooding, you will want overhead lines.
