PG&E will soon test 3.6 miles of natural gas transmission line running along Second Street in Davis.
On July 16, the utility will begin excavating the road at several points along Second Street where it will dig up the 10-inch steel transmission line and test it using hydrostatic pressure, hosing water through the gas system to analyze whether the system contains any flaws that might pose dangers to residents.
What: PG&E open house to discuss hydrostatic testing project
When: 5-7 p.m. Tuesday
Where: Comfort Suites, 1640 Research Park Drive
The process is supposed to take about one month.
The testing will take place between the PG&E service yard at Second and L streets and the PG&E valve lot at the end of Howat Street, east of County Road 105. The utility also will excavate two points along Second Street along the PG&E service yard and east of Cousteau Place.
Traffic may need to be diverted while the work is under way.
Crews will remove the segment of pipe they are testing from service about July 30 and vent the natural gas. PG&E will be ready to test the pipe about Aug. 10 and hopes to complete the project by Aug. 15.
Residents also should be aware that they might smell gas and/or hear a loud noise while crews remove the transmission line pipe from service, Ehlers said.
The utility does not foresee any interruption in service.
Last year, PG&E hydrostatic-tested 160 miles of transmission lines throughout its system in the state and the utility plans to test 185 more miles this year.
