Hydro Jetting for Buried Drain and Sewer Lateral Lines
An independent, licensed plumbing contractor. Not affiliated with Denver Water or the City and County of Denver.
Hydro jetting uses a high pressure water stream to strip roots, grease, and mineral scale from the walls of a buried drain or sewer lateral, restoring the pipe's full diameter instead of just punching a hole through the blockage. Denver Sewer and Water jets the underground run from the building drain to the connection, not the interior branch lines behind fixtures.
- High pressure jetting sized to the buried pipe diameter.
- Root cutting, penetrating, and descaling nozzle heads.
- Camera survey before and after jetting to confirm results.
- Grease, scale, and root mass stripped from pipe walls.
- Residential and commercial buried drain and lateral lines.

When Does a Buried Line Need Jetting Instead of Snaking?
Cabling clears a path through a clog. It does not remove grease coating the pipe wall, it does not strip root hair growing through a cracked joint, and it does not touch mineral scale that has built up on older cast iron or clay pipe over decades. Those all narrow the working diameter of the line even after a cable has made it passable again, which is why a cabled line so often clogs again in the same place.
We recommend jetting when the camera shows buildup coating the pipe wall, roots that have grown into a mass rather than a single strand, or a history of the same section clogging repeatedly despite regular cabling. On a buried line already confirmed sound by camera, jetting is a maintenance tool as much as a repair.
(720) 935-6221Signs a buried line needs jetting rather than cabling
- The same section of buried line clogs again within weeks of cabling.
- Camera shows grease or scale coating the pipe wall.
- Root mass has grown through a joint rather than a single strand.
- Flow is consistently slow even between full blockages.
- The line has not been cleaned in several years and its condition is unknown.
How a Buried Drain Jetting Job Runs
- 1
Camera survey first
We run the camera to confirm the pipe is structurally sound enough to jet and to see what is actually coating the wall.
- 2
Locate and mark depth
Where the line's path is not already documented, a sonde locate marks it before work begins.
- 3
Select the jetting nozzle
A root cutting head for root mass, a penetrating nozzle for a hard blockage, or a descaling head for grease and mineral buildup, matched to what the camera found.
- 4
Jet the full run
The hose is fed to the far end and pulled back, scouring the pipe wall on the return pass rather than just the blockage point.
- 5
Post-jet verification scope
The camera runs the line again to confirm the wall is actually clean, not just that water is flowing.

What Drives Buried Drain Jetting Cost
Line length, pipe diameter, how much material has to come off the wall, and whether the line needs locating before access all move the number. A line already confirmed clean by camera with a known access point is a straightforward job.
We camera before jetting because high pressure applied to a cracked or separated pipe can widen the defect, and that inspection sets the price instead of a guess.
