Clean Trenches, Marked Utilities, No Surprises

Trenching & Utility Excavation

Water, sewer, gas, electrical conduit, low-voltage, footings, and French drains — trenched to depth and grade, DigAlert-coordinated, with spoils managed or hauled. One crew for the pool run, the ADU utilities, and the drainage fix.

We trench for: pool plumbing and electrical runs, new service laterals, ADU utility extensions, footing and grade-beam excavation, French drains and area drains, and irrigation mainlines. Depths and bedding to code and to your engineer's detail; California-required DigAlert 811 marking handled before we cut.

Common trenching jobs

Pool utility runs

Gas to the heater, electrical to the equipment pad, plumbing runs — trenched alongside our own pool digs or as a standalone.

ADU utilities

Sewer, water, and power from the main house or street to the new unit — often the sneaky-hard part of an ADU project.

Drainage systems

French drains, area drains, and downspout tightlines that actually move water off the property.

Trenching: Frequently Asked Questions

How deep do utility trenches need to be?

Depth is set by code and utility type — commonly around 12–24 inches for irrigation and low-voltage, 18–24+ inches for gas and electrical, and deeper for sewer laterals which also need consistent fall. We trench to the governing code and your plans.

Do you locate existing utilities first?

Always. DigAlert 811 marking is required by California law at least two working days before digging, and we hand-expose near marked lines.
