This helps prevent unintended consequences from digging into an underground utility such as injury, damage to property and service outages.
Founded in 1984, the non-profit Texas811 is the largest one-call notification center in the country. We protect billions of dollars of underground utilities and the people who live and work around them.
We notify utility companies that are registered with Texas811 of the planned excavation, and they send locators to mark their underground utility lines. These markings represent the approximate location of the underground utility lines.
Texas811 is the link between your plans to dig and our member utility companies.
Texas811 members are utility companies and municipalities who choose Texas811 to provide them notifications of planned excavations near their underground lines.
Our mission is to facilitate damage prevention, promote public safety and protect the environment through stakeholder education and communication.
To educate excavators, emergency responders and the public, Texas811 hosts damage prevention educational events; an annual Summit and training sessions. Texas811 manages the largest Facebook page of any state one-call organization in the country, which helps educate the general public about underground safety.
