Utility Trenching In Montrose

Trenches for Water, Sewer, Gas, Electric & Communications Lines Around Montrose

Getting Utilities From the Street to Your Building

New homes, shops, additions, and commercial buildings all need water, sewer, and power run underground, and often gas and internet too. Each trench has to reach the right depth, hold a steady grade for sewer lines, and stay safely clear of anything already in the ground.



El Chapin Excavation digs utility trenches for homeowners, builders, plumbers, electricians, and commercial projects around Montrose. Once the lines are in, we backfill and compact the trench so the surface holds up.

How a Utility Trench Comes Together

Locates & Route Planning

Existing lines are marked through Colorado 811, and we plan a safe route from the connection point to your building.

Trench Excavation

We dig to the depth and width your lines require, keeping sewer trenches on a consistent downhill grade.

Trench Bottom Prep

The bottom of the trench is cleaned out and shaped so bedding material, pipe, and conduit sit evenly.

Line Installation

Your plumber, electrician, or utility provider sets the lines and has them inspected.

Backfill & Compaction

We backfill the trench in layers and compact each one to limit settling later.

What Different Utility Lines Need From a Trench

Water Lines

Water lines have to run deep enough to stay below the frost line so they don't freeze during Colorado winters.

Sewer Lines

Sewer lines need a steady downhill slope from the building to the main or septic system so waste keeps flowing.

Gas Lines

Gas lines follow the gas provider's depth and separation requirements, which often means keeping them apart from other utilities.

Electric WORK

Required depth depends on the type of line and conduit. These lines can sometimes share a trench with others when code-required spacing is kept.

When Your Property Would Need Utility Trenching

  • You're building a new home, shop, or commercial building that needs service lines.
  • You're connecting to city water or sewer for the first time.
  • An old water or sewer line needs to be dug up and replaced.
  • You're running power to a barn, well pump, gate, or outbuilding.
  • Your plumber or electrician needs a trench open before they can install.

Utility Trenching Questions & Answers

  • How deep does a utility trench need to be?

    It depends on the type of line, local code, and frost depth. Water lines usually run deepest, while electric and communications lines vary. Your plumber, electrician, or utility provider will specify the depth before we dig.

  • How much does utility trenching cost?

    Utility trenching cost depends on the length and depth of the trench, soil and rock conditions, and whether we have to cut through concrete, asphalt, or landscaping. We look at the route, then quote the job.

  • Who installs the pipe or conduit after utility trenching?

    Usually your plumber, electrician, or utility company. We dig and prep the trench, then come back to backfill once the lines are installed and inspected.

  • Will utility trenching tear up my yard?

    There will be some disturbance along the trench route. We keep the trench only as wide as the job needs, set the soil aside, and backfill and compact it when the work is done. Reseeding or landscaping can follow.
