Private-Property Utility Work
What we trench in Dublin
Our utility work happens on your lot: the run from the meter or PG&E's service point to the building. In Dublin that's mostly new homes, ADUs and electrification projects that need a bigger service or a new conduit path.
Joint trench on new lots
One trench carrying gas, electric and communications to a new home, laid out to PG&E's design and sequenced with each utility.
Gas service lines
New or upsized gas lines from the meter to the house, a backyard ADU or a new appliance. See our gas line services.
Conduit for ADUs and EV chargers
Trenching for conduit to an ADU, a detached garage, an EV charger, or a panel upgrade that needs a new service path.

How a new PG&E service trench works
When PG&E extends gas or electric service to a new home or ADU, its Rule 16 puts the trenching, backfill and permit fees on the property owner's side. PG&E designs the service, then inspects and approves the work. We dig to that design and coordinate the inspections.
Before any digging, we file a ticket with USA North 811. California law requires at least two working days' notice, not counting the day you call, and the ticket is good for 28 days.
Common Questions
Dublin trenching questions
Yes. Dublin Building & Safety requires permits for electrical and plumbing installations, gas lines included. If the work also connects to DSRSD water or sewer, DSRSD reviews it separately, and the City issues the building permit only after DSRSD signs off. We pull the permits for the work we do.
Any work in the public right of way needs one from Public Works Engineering. In Dublin that strip runs about eight feet back from the face of the curb, so a trench that stays behind it is a building permit job only. The City says to allow up to 30 working days for review.
It marks lines a utility owns. USA North 811 says private lines, like irrigation and landscape lighting, are not marked because no utility owns them. That includes a gas line or a power feed a past owner ran to a shed or garage. Inside 24 inches of any line, marked or found, we dig by hand.
You do. DSRSD says the property owner is responsible for the service pipeline between the house and the water meter. If your trench is replacing or adding a water line, we can run it in the same dig. DSRSD also needs a permit for sewer lateral repair or replacement, cleanouts included.
