Septic System Excavation on Denver Area Parcels
An independent, licensed plumbing contractor. Not affiliated with Denver Water or the City and County of Denver.
Septic excavation is the machine work that exposes a tank, a lid, an outlet, or a buried line so that repair or replacement can happen. Denver Sewer and Water runs its own excavation crews, which means the locating, the digging, the shoring, the backfill, and the surface restoration are all one company's responsibility.
- Own crews and own equipment, not subcontracted.
- Utility locating before any machine moves.
- Tank, lid, outlet, and line exposure.
- Shoring and safe trench practice on deep work.
- Backfill, compaction, and surface restoration included.

Why Does Septic Work Need Excavation at All?
Because there is no other way to reach the components. A septic tank sits below grade with a lid that may or may not have a riser to the surface. The outlet, the distribution box, and the line between the building and the tank are all buried at working depth. When any of those fails, soil comes off before repair goes on.
Excavation is also what makes a real inspection possible on older systems. A tank whose lid has been buried for thirty years has never been looked at. Opening it is often the first time anyone has seen the baffles, and it is regularly where the actual problem turns up.

How We Diagnose It
How We Plan a Dig Before Anything Moves
Utility locating comes first. Gas, electric, water, and communications lines cross septic runs constantly on older parcels, and a machine that finds one of those has turned a septic job into an emergency. Public locate plus our own tracing establishes what is in the ground.
Then the excavation itself gets planned: where the machine sits, where spoil goes, what the access route is, and what the surface has to be restored to. Planning spoil placement sounds minor until a crew has stacked a day of clay across the only lawn the owner cared about.
Pre-excavation checklist
- Public utility locate requested and marks verified.
- Line and tank traced and marked on the surface.
- Depth established so shoring needs are known in advance.
- Machine position and spoil placement agreed.
- Restoration standard confirmed for the surface being cut.
How a Septic Excavation Runs
- 1
Locate and mark
Public locate plus our own tracing. Nothing moves until the marks are verified on the ground.
- 2
Open the excavation
Machine work down to working depth, with shoring or benching where the depth and the soil require it.
- 3
Complete the repair
The septic work itself, inspected before anything is covered.
- 4
Backfill and restore
Compacted backfill in lifts, then the surface put back to the standard the original surface demands.
What Denver Customers Say About Working With Us
“We had an underground water valve break on a Saturday. No fun and expensive to fix regardless of the repair company. Nevertheless, greatly apprecia”
“Very direct and to the point. Extremely efficient and professional.”
“They cleared our drain where Roto Rooter couldn't and quoted us to replace the line under our concrete.”
What Drives Septic Excavation Cost
Depth is the largest factor, because depth drives both the volume of soil moved and the safety measures required. Access is second: a parcel a machine can drive onto is a fundamentally different job from one where the tank sits behind a fence line with a narrow gate.
Surface type is third. Turf goes back cheaply. Concrete, pavers, and asphalt do not, and a repair under a driveway carries its restoration cost whether anyone budgeted for it or not.
