Utility Trenching

Utility Trenching in Broomfield, CO

Trenching for water, sewer and electric service lines. Clean, straight trenches to the depth your plumber or electrician needs, then backfilled and compacted.

Clean trenches, on line and on grade

Your plumber and electrician need a trench that's the right depth, the right width and in the right place. We dig to the depth they need, keep the bottom clean, and come back to backfill and compact once the lines are in and inspected.

Locates first, every time

Before any trench, we make sure an 811 locate is in and existing lines are marked. On acreage with private lines we'll ask what you know about the property so nothing gets hit.

Runs to shops, barns and new buildings

A lot of our trenching is for new detached shops and barns that need power and water run from the house or the road. We coordinate with your electrician or plumber so the trench is open when they're ready.

Common projects

  • Power to a shop or barn: trenching for conduit from the house or meter to a detached building.
  • Water service: trenching below frost depth for new or replacement water lines.
  • Sewer service: trenching on grade for new sewer connections.

Why one crew for the whole site

When the same crew digs, preps, trenches, backfills, grades and pours, nothing falls between the cracks. We know where the utilities went, how the backfill was placed and what the base looks like under the slab, and you have one person to call if something needs attention.

Our process

How trenching works

  1. Plan the route

    We mark the route with you and your trades, and confirm the required depth.

  2. Locates

    An 811 locate is requested and existing lines are marked before we dig.

  3. Dig the trench

    We dig a clean trench to the depth and width needed, keeping spoil to one side.

  4. Backfill after inspection

    Once lines are installed and inspected, we backfill in lifts and compact.

Pricing

What affects the cost

Every site is different, so we price after seeing the ground. These are the things that move the number most. Estimates are free.

Length

Longer runs take more time and more backfill work.

Depth

Deeper trenches (for example below frost for water) move more dirt.

Ground conditions

Rock, roots, clay or existing utilities can slow the work.

Crossings

Crossing drives, walks or existing lines may need extra care or repair.

Surface restoration

Lawn, gravel or concrete repair after trenching can add to scope.

Coordination

Timing with plumbers, electricians and inspections can affect how many trips are needed.

Common questions

FAQ

How deep do water lines need to be in Colorado?

Water lines need to be below the frost line, and the required depth is set by the local code and utility. Your plumber or the utility will give the depth, and we dig to it.

Do you install the pipe or wire?

We dig and backfill. Your licensed plumber or electrician installs and connects the lines; we coordinate timing with them.

Can you trench to a detached shop or barn?

Yes. Runs to shops, barns and outbuildings are a big part of our trenching work.

Do you handle backfill after inspection?

Yes. Once the lines are inspected, we backfill in lifts and compact so the trench does not settle.

Can multiple lines share one trench?

Sometimes, depending on the utilities and local requirements. Your plumber, electrician or the utility will tell you what is allowed, and we dig accordingly.

How wide is a utility trench?

Usually just wide enough for the pipe or conduit and bedding, but it depends on depth, soil and what is being installed.

What happens to my yard after trenching?

We backfill and compact the trench and can grade the surface back. Lawn or landscaping restoration can be discussed as part of the bid.
