What we trench in Pleasanton
We're a C-36 plumbing contractor based in Hayward and PG&E OQ qualified for gas and electrical work. In Pleasanton our trenching is on private property, from the meter or PG&E's service point to your house, ADU or new building.
Service upgrades
The trench for a bigger electric service when a panel upgrade, heat pump or EV charger needs more power from PG&E.
Gas service lines
New or upsized gas lines from the meter to the house or an ADU. See our gas line services.
ADU and garage conduit
Trenching for conduit to a backyard ADU, an addition or a detached garage, sized for what you plan to run there.

When the run also carries water, we lay it in the same dig. See our water line services.

City of Pleasanton: Standard Specifications (2024)PG&E Standards
How deep a service trench goes
PG&E's Greenbook calls for at least 24 inches of cover over a residential electric service, measured from the top of the conduit to finished grade. With bedding and sweeps, the trench usually ends up around 30 inches deep.
For gas, PG&E's gas design standard sets at least 24 inches of cover over a service in a gas-only trench. A joint trench follows PG&E's joint trench standard, and PG&E can ask for more cover where conditions call for it. We confirm the depth on the PG&E design before we dig.
Common Questions
Pleasanton trenching questions
Yes. Pleasanton requires a permit from the Building and Safety Division before anyone installs, alters, repairs or replaces an electrical, gas or plumbing system. The Permit Center is at 200 Old Bernal Avenue, next to the City Council Chambers. We pull the permits for the work we do.
Only if part of it is in the public right of way. Pleasanton Engineering issues encroachment permits for excavating or trenching there, including utility work on the street. If you are not sure, the City says to call Engineering at (925) 931-5650.
Under PG&E Rule 16, the property owner is responsible for the trenching, backfill and permit fees for a new service extension. PG&E designs the service and inspects the work. That digging is the part we do, along with the inspection scheduling.
It depends on the property. Pleasanton requires a backflow device on all non-residential water connections, and on homes where the City has found a hazard, like an on-site well, a booster pump or an unprotected fire sprinkler system.
