Sewer Line Tap Services for Denver Properties
An independent, licensed plumbing contractor. Not affiliated with Denver Water or the City and County of Denver.
A sewer line tap connects a property's sewer service to the public sanitary main, and Denver Sewer and Water installs, connects, and repairs those taps across the Denver metro. The wastewater authority with jurisdiction owns the main and approves the connection. We perform the excavation and the physical tap under that approval.
- New sewer tap installation and replacement.
- Tap connection at the main, made to the approved detail.
- Repair of failed, leaking, or root-damaged taps.
- Deep excavation with proper shoring.
- Coordination with the wastewater authority on permitting and inspection.

When Does a Property Need Sewer Tap Work?
New construction with no existing sanitary service needs a first-time tap. Properties converting from septic to public sewer need the same thing. Beyond new work, taps come up when an existing connection at the main has failed and cannot be repaired in place, when a shared service is being split into separate connections, or when a previously abandoned service is being reconnected.
The tap itself is usually a small part of the visible work and the largest part of the risk. It happens at depth, often in the public right of way, and it has to be inspected by the authority before the trench closes. Getting the connection type wrong or missing the inspection window turns a routine tap into a redo.

How a Sewer Line Tap Project Runs
- 1
Locate the main and verify grade
We confirm main depth, material, and position and check that there is workable fall from the building before anything is designed.
- 2
Coordinate with the wastewater authority
The connection type, location, and permit requirements are confirmed with the authority having jurisdiction before excavation.
- 3
Right-of-way and traffic control permitting
Where the tap sits in a public street, the required street cut and traffic control permits are secured.
- 4
Potholing and utility locates
Other buried utilities are located and the connection point is exposed carefully before the main is opened.
- 5
Make the connection and shore the trench
The tap is made to the approved detail with proper shoring, and the service is set to grade.
- 6
Inspect, backfill, restore
The authority inspects the open connection, then we backfill in lifts, compact, and restore the surface to spec.

What Denver Customers Say About Working With Us
“They cleared our drain where Roto Rooter couldn't and quoted us to replace the line under our concrete.”
“Prompt service and worked well into the night to restore service due to hard soil. And did their best to prevent large scars to the yard”
“Denver Water And Sewer did an excellent job replacing my sewer lines. Trevor and his crew are extremely competent, honest, professional and prompt.”
What Drives Sewer Line Tap Cost
Depth is the biggest driver, because sanitary mains sit lower than most other utilities and depth changes the shoring, the equipment, and the labor. Distance from the building to the main, soil and groundwater conditions, and whether the work falls in a driveway, a street, or open ground all move the number as well.
Tap fees, system development charges, and permit fees are set by the wastewater authority with jurisdiction over your address, not by us. We do not publish fee amounts because they vary by jurisdiction and change on the authority's schedule. We confirm current figures with the authority before work is scheduled.
