Under Maui's dirt are water mains, power lines, gas lines and fiber. Hawaiʻi law requires anyone excavating to notify the state's One Call Center first. It's free, and it's the cheapest insurance on any dig.
Who to call
Dial 811, or 1-866-423-7287, to reach the Hawaiʻi One Call Center. The center takes your request and passes it to the utility companies, who send locators to mark their lines. It's run under the state Public Utilities Commission and is available 24 hours a day, 7 days a week. Online ticket requests are available around the clock too.
When to call
- At least 5 working days before you dig, and not more than 28 calendar days before.
- Requests made after 5 p.m. or on a holiday start the five-day clock on the next business day.
- Marks are valid for 28 calendar days from the date of issuance.
Homeowners too
It's not just for contractors. Hawaiʻi Gas encourages homeowners to call 811 before any project that involves digging, even planting a hedge or setting a mailbox or fence post.
On the day
- Look for paint and flags. Each color stands for a utility type (red for electric, yellow for gas, blue for water, orange for communications, green for sewer).
- Hand-dig carefully near the marks; the marks show an approximate location, not an exact depth.
- If you hit something, stop and call the utility. If you smell gas, leave the area and call 911.
Every good contractor in our directory handles 811 as routine. Ask yours to confirm the ticket number before work starts. Landlords planning fence or yard work at rentals can coordinate with Maui Property Managements.
