Underground Pipelines in Corpus Christi

CORPUS CHRISTI - After what happened in Milford yesterday, we decided to take a look at underground pipelines here in Corpus Christi.

Truth is there are tons of pipelines that run all over the city, underneath the ground, right near your homes.

The pipelines that exploded in Milford is what's called a natural gas transmission pipeline. It carries large amounts of natural gas from one location to another.

And while it's not a common occurence, when a natural gas transmission pipelins erupts, the results can be disasturous.

The reason is the amount of pressure those pipelines typically have, anywhere from 500 to 700 pounds of pressure.

To put that in perspective, the distribution pipelines that run gas to homes only have about 12 pounds of pressure.

Transmission pipelines are typically anywhere from 8 to 12 feet underground.

We talked to one homeowner who lives right off Leopard, where a major transmission pipeline runs.

He's lived there for 18 years and never knew the pipeline was there.

"If there was a leak, natural gas is not going to explode on it's own. It would need a spark or something, but either way, I'm glad you're telling me, I didn't know," Frank Basaldua says.

The Fire Department and the Local Emergency Planning Committee work closely with industry to make sure these pipelines are safe.

The department says you at home don't really need to worry, but anyone doing excavation work might consider giving them a call to make sure a pipeline isn't under them.

You've probably seen the markers around town that say "Call Before You Dig".

Those are markers that mark these underground pipelines.
