Pipeline Fusing is Complete

Pipeline Fusing

The fusing of pipeline near lakes four and five at Santee Lakes is complete.

In early December 2023, crews wrapped up the 8-inch pipeline fusing, marking the completion of this process. 

Air and water testing is nearly complete to ensure there is no leaking in the pipes. From there, these pipes will be pulled underground as part of the Horizontal Directional Drilling process. All three pipelines will run from East Mission Gorge Pump Station near State Route 52 to lake one.

After installation, lake visitors can expect additional work on the west side of lakes one, two and three.

HOW DOES FUSING WORK?

For the 8-inch fusing process, the pipeline was cut into 50 foot pieces and each side was heated with a plate at 425 degrees Fahrenheit. The hot plate was removed and the two sides were melted and fused together with pressure at 225 pounds per square inch (PSI). In between six to eight pieces were fused together in a typical day. The other two pipes underwent the same process with varying degrees and pressures.

Fun facts: An 8-inch 50 foot pipe weighs 200 pounds and is 1.25-inches thick!
