Sewer Line Repair in LoHi, Denver
An independent, licensed plumbing contractor. Not affiliated with Denver Water or the City and County of Denver.
LoHi has been rebuilt above ground far faster than below it. New construction sits over laterals installed between the 1920s and 1945, and those older lines often carry loads the original build never anticipated. Denver Sewer and Water inspects before assuming anything.

New Buildings, Reused Connections
Redevelopment frequently keeps the existing sewer connection. That decision is reasonable and it is also the source of most LoHi sewer calls, because a 1930s lateral now serves a duplex or a much larger single home.
Construction itself adds stress. Heavy equipment, trenching for other services, and backfill compaction near the run all act on jointed pipe that was already near the end of its comfortable service life.
(720) 935-6221What LoHi's 1920s to 1945 Blocks Have Underground
- Clay tile on one stretch and cast iron on the next, sometimes within the same lot.
- Laterals rebuilt in pieces over the decades, leaving mixed materials in one run.
- Uneven fill under LoHi's blocks producing bellied sections in older lines.
- Interior scale on the cast iron portions reducing usable flow.
- Longer laterals than you'd find near downtown, a holdover from the original platting.
- Street trees planted when these blocks were first built, now grown in over the pipe.
How We Diagnose It
Verify the Old Line Before Trusting It
Anyone buying, building, or finishing a project in LoHi benefits from a documented camera inspection of the reused lateral. It is a small cost against the price of discovering the problem after the driveway is poured.
When the inspection finds trouble, timing is the advantage. Replacing a lateral before hardscape and landscape go in costs a fraction of doing it after, and bursting can often reuse the existing path.
Where a project changes fixture count or building use, connection and permit requirements are confirmed with the city for that address. We perform the work; the city and utility authorize it.
The Repair Path We Use on LoHi Laterals
- Camera inspection to pinpoint exactly where a LoHi lateral shifts from clay to cast iron.
- Descaling cast iron sections before any repair method is chosen.
- CIPP lining on clay joints that remain intact and on grade.
- Open cut for any section that has bellied, since no liner restores fall.
- Pipe bursting when the lateral as a whole has reached the end of its service life.
How We Approach a LoHi Sewer Project
- 1
Document the Material Layout
LoHi laterals often show two or three materials in a single run, a result of piecemeal replacements over the years. The camera pass documents where each section starts and ends before we recommend anything.
- 2
Look for Standing Water
We flush the line and watch for pooling, since a belly is the most common defect from this era's fill and rules lining out for that stretch.
- 3
Fit the Method to Each Section
A LoHi lateral rebuilt around older lines can often be lined in one section and excavated in another. Matching the method to each section keeps the project from turning into a full replacement.

Camera-Verify the Finished Line
After the repair we run water and re-camera to confirm the line drains properly, then return the surface, whether alley, walk, or yard, to its original state.

What Drives Cost on a LoHi Line
The biggest cost driver on a LoHi lateral is whether a belly shows up during inspection. Grade loss means excavation, and that is where the cost concentrates.
LoHi's blocks were rebuilt around the original streetcar-era lines in places, so lateral length and routing can vary block to block, affecting how much line needs work.
Redevelopment nearby and finished hardscape on these lots factor into how much restoration a repair calls for.
