17 years of proven experience across the Pacific Southwest.

Founded by professionals for professionals.

What do you do when you cannot find safe, fast, economical, AND accurate underground utility locating? You do it yourself! Founded in 2003, Underground Solutions (USI) was formed out of necessity by experienced utility contractors with over 60 years of combined underground utility pipeline construction, installation and rehabilitation expertise.

Our business has exploded as more engineering firms, water & sewer districts, municipal customers and utility contractors have realized the need to perform due diligence, because of the high costs of repairing underground utilities that were not properly located and documented over decades.

After 17 years of utility locating in Southern California, USI expanded operations into Arizona and opened a branch in Scottsdale in early 2019. Our continued successes have now spread into the desert southwest.

USI has partnered with over 600 municipalities, utilities, engineering firms and contractors in both states over the last 5 years alone.

What differentiates our services from our competitors, and from 811? We locate what 811 does not.

When you use 811 prior to any excavation work within your public-side dig area, utility companies and local governments mark only what they own and operate – typically to the meter. Our Locating Services identify all private-side utilities within your dig area beyond the meter – including gas lines, electrical conduits, water lines (plastic or metal), and sewer lines.

Our team is dedicated to providing you with safe, efficient and accurate utility locating. Our locating technologies will keep your critical projects on schedule, your staff safe, and prevent you from realizing the costly damages and fines that come with damaged underground assets.

Make USI your first and only choice for underground utility locating services in California and Arizona.

These California companies have partnered with USI Locate for their SUE needs.
