Sewer Line Repair in Denver, CO

• Service covers Wash Park and Congress Park near I-25 and the Highlands and Berkeley north toward I-70.
• Denver DOTI requirements apply in the City and County of Denver.
• Aurora, Lakewood, Englewood and Wheat Ridge can use different utilities or sanitation districts; confirm local approvals and service availability.

• Locating the Denver owner-maintained lateral and tap
• Correcting a documented sewer grade defect under DOTI inspection
• Planning an approved outdoor trenchless launch with post-repair video
• Hydro-jetting or cable clearing of a recurring residential sewer blockage

• The Denver DOTI 2026 sewer permit fee sheet lists a single-family connection at $410 SAFE fee plus $6,070 Metro fee, for $6,480 per unit.
• The same Denver DOTI fee sheet sets a reactivation charge of $165 per SFRE for each year beyond the allowed period.
• Method: these are published fee schedule amounts; repair labor is priced per linear foot and by depth, and Denver's wastewater FAQ says the City is only responsible for main public sewers, so a local quote includes the tap and street section.
• The Denver private scope can reach the street tap, so the quote should include locating, access and restoration for that full route when needed.
• Under DOTI's published guidance, trenchless staging begins outside the building and requires approval and video review; ask how these steps and a failed review would be priced.
• The CGS report supports checking bedding and ground conditions in the Denver metro, with excavation assumptions tied to your actual route rather than a citywide soil label.

• Denver issues sewer permits through DOTI under its 2026 fee sheet ($6,480 per new single-family unit), and private plumbing follows the Denver Building and Fire Code.
• Step 1: camera the line and locate the tap. Step 2: request utility locates. Step 3: obtain the DOTI sewer permit and any right-of-way permit. Step 4: pass inspection before restoring the street.
• As reviewed in October 2026, Denver DOTI says lateral responsibility extends through the tap into the main. Contact Colorado 811 at least three working days before planned digging and arrange identification of the private run separately.
• DOTI's PW repair/SUDP guidance requires advance approval for trenchless work and distinguishes a new tap's Sewer Use and Drainage Permit from a PW repair permit. Confirm the repair permit and sewer-layer authorization with DOTI; indoor/near-building plumbing licensing is administered by Colorado's State Plumbing Board.

• Colorado Geological Survey's Denver-area report identifies swelling soils, settling soils and potential landslides as construction concerns. It explains that clay and clay-shale soils can swell with moisture; the report is regional context, not proof of movement beneath a particular lateral.
• Denver DOTI's repair guidance rejects lines holding water and requires post-repair video review. Have a measured sag or grade problem evaluated before assuming lining will resolve it.
• By the Census Bureau's 2024 ACS count, 221,895 housing units in Denver, 60% of 372,123, were built before 1990, and 118,048 were built before 1960.
• Expansive clay soils and bentonite pockets on the west side, plus freeze-thaw cycles, stress clay tile laterals under older homes in neighborhoods near downtown.
