PG&E has a sizable pipe replacement project underway on Las Ramblas Dr. (off Concord Blvd. near Kirker Pass) and the surrounding streets in Concord.

Our friend “Kirkwood” tells us “The project involves replacing all of the main gas lines and service laterals to houses in the neighborhood. Purpose of the project is to replace all of the old plastic lines that were installed when the tract was built around 1974. A PG&E onsite inspector said that the old plastic gas lines could become brittle with age and are being replaced with better material. The project utilizes a boring machine that quickly tunnels from trench to trench. The work is being done by a contractor and monitored by a PG&E inspector, and will extend through the month of January and possibly into February.”

There are numerous trenches in the street and driveways, so please use caution if you’re in the area.

Thanks to “Kirkwood” for the information and for the pictures!

Interesting, a product was used that college degree “engineers”, planners and cities all thought was long lasting and safe.

It is my understanding that at the time they were using that type of pipe they did not know that it being exposed to uv rays (aka sunlight) would cause premature failure of the pipe. You have to remember that this was probably the 1st generation of the pipe that they use now and it is stored and handled differently and has a coating to protect it from uv rays.

gman – The pipe is underground.

40 Years ago, the technology of plastics wasn’t what it is today and engineers of the time didn’t foresee that the evaporation of solvents in plastics over time, would make them become brittle. Remember that “new car” smell back in the old days? That largely doesn’t exist today.

I think something that survives 40 years underground can be described as “long-lasting”. You must expect pipes to last forever with no maintenance.
