Inspections completed with no safety incidents and three years ahead of schedule
SDG&E recently completed the Sewer Lateral Inspection Program (SLIP) that addresses a rare, but potentially unsafe/hazardous condition where the natural gas pipeline is bored into the earth and inadvertently penetrates a sewer lateral pipeline. The SLIP kicked off in mid-2011 and was expected to continue into 2015 but the team safely completed the program December 21.
In just over a year the SLIP project team visually inspected 6 percent of SDG&E’s gas pipelines by using video cameras or by digging out an area over the sewer line to make sure the gas pipeline clears the sewer line. During the inspection of more than 1,500 gas mains or 350 miles of pipeline the team found no incidents of gas line intersections and one instance of minimal damage to a sewer line, which was fixed the same day it was identified.
The SLIP team celebrates the near completion of the project at one of the final project meetings
