If you’re digging, get permission first – ALWAYS

Similar to other utilities like electricity, telephone, internet and TV cables, water and sewer connections, our pipelines are under the ground. Unfortunately, unauthorized construction and digging are leading causes of damage to pipelines and other utilities.

In order to keep you and your family safe, we need your help.
