2009 CGA DIRT Report: Utility Damages Decline Again

October 2010 Vol. 65 No. 10

The Common Ground Alliance (CGA), the leading organization focused on protecting underground utility lines and the safety of people who dig near them, announced that underground utility damages in the U.S. decreased to an estimated 170,000 in 2009, down 15 percent from 2008, and down 58 percent from 2004.

This data was released as part of CGA’s Damage Information Reporting Tool (DIRT) Report, which CGA issues annually as part of its continuing mission to identify the contributing factors and root causes of underground utility damages and near misses. DIRT, developed in 2003, is CGA’s secure web application for the collection and reporting of underground damage information.

Of the total number of damages reported in 2009, nearly 60 percent had a known root cause, and the top causes were identified as follows:

1. Excavation practices not sufficient: Root cause for 38 percent of reported damages.
For these damages, excavators notified the one call center to have underground utilities marked, but damage still occurred due to the lack of careful excavation practices around the marks.

2. One call center notification not made: Root cause for 34 percent of reported damages.
The first step in the damage prevention process, excavators must contact their local one call center by calling 811 a few days before digging. These damages were caused due to the failure of the excavator to contact the one call center.

3. Locating practices not sufficient: Root cause for 24 percent of reported damages.
These damages were caused when excavators, who had contacted their local one call center before digging, struck an underground line (or lines) that the facility operator did not properly or accurately mark.

Improvements in One Call Center Usage
Damages reported with “notification not made” as the root cause are down approximately 70 percent from 2004, the year of the first DIRT Report.

CGA stakeholders have greatly increased their promotion of one call notification centers since the initial report, aided in large part by the launch of 811 in May 2007 as the national call-before-you-dig phone number, allowing for consistent one call messaging across stakeholder groups and state lines.
