Common Ground Alliance (CGA)
The Common Ground Alliance (CGA) promotes the 811 phone number and other damage prevention initiatives. CGA members can promote 811 through events, social media, and other methods. CGA also maintains a map of one call centers and damage prevention information by state.
DPI, Dirt, and 811 are all related to damage prevention and excavation safety:
-
DPI
The Damage Prevention Institute (DPI) is an initiative of the Common Ground Alliance (CGA) that aims to improve shared accountability for damage prevention.
-
DIRT
The Damage Information Reporting Tool (DIRT) is a tool from the CGA that collects data to evaluate the safety performance of those involved in damage prevention.
-
811
811 is a national toll-free number that people can call before digging to request that buried utilities are marked.
Here's some more information about each of these:
-
DIRT
DIRT's Query Wizard allows users to sort data, create graphs and tables, and generate customized reports. The Data Grants feature in DIRT allows organizations to share data with each other.
-
811
Calling 811 before digging is the primary way to prevent excavation damage and injuries. Research shows that people who call 811 have a 99% chance of avoiding an incident.
-
DPI
The CGA was founded on the idea that reducing damage to underground utilities is a shared responsibility. The CGA has been working to reduce utility damage for over 20 years.
Always call 811 before you dig!
