Blue Stakes currently has over 600 participating facility owners/operators. There are large and small companies including gas, power, communications, water, sewer, municipalities, and more. Each participating member should ensure the lines that they own and maintain are located and marked within the described areas on Locate Request Tickets. Some of these members hire third party locating companies to do their required locating and marking on their behalf.
