Navajo Tribal Utility Authority®
NTUA has a vast network of electric, natural gas, water and wastewater utility lines.
Some of these lines are underground and out of site. These lines are very dangerous if exposed or damaged. Because safety is our number one concern, we encourage everyone to exercise extreme caution when digging around any of our utility lines.
Please call the NTUA at 928-729-5721 if you have any questions.
