When a sewer line needs replacing instead of repairing
A new sewer line is the answer once the old one has stopped being worth repairing. That is the case when damage spreads along much of the run, when a section has collapsed, or when the material itself is failing. Repeated spot repairs in one line, a long sag that holds water, and Orangeburg pipe (bituminized fiber, found in many homes built from the 1940s to the early 1970s) are the usual triggers.
Sewer line replacement means installing a new line from the house connection to the main, either by pulling new pipe through the old path or by digging a trench. Spot fixes and linings are covered under sewer line repair. New plastic sewer pipe is commonly PVC made to ASTM D3034, the specification for PVC sewer pipe and fittings.
Trenchless or open trench: how the two compare
| Factor | Pipe bursting (trenchless) | Open trench |
|---|---|---|
| Yard and driveway | Entry and exit pits only | A continuous trench along the line |
| Best for | Straight runs of failing pipe | Collapsed, bellied or tangled lines, and changed routes |
| Route | Follows the old line | Can change the route and the slope |
| Limits | Does not suit every pipe or soil, and nearby utilities matter | Most disruptive and slowest to restore the surface |
| Pipe used | New plastic pipe pulled in | New plastic pipe laid in the trench |
Wondering if you need a new line?
Call and we will start with a camera inspection.
What a replacement job involves
- 1
Inspect and scope
Camera footage and a locator establish the length, depth and route.
- 2
Locates and permits
811 marks public utilities, a private locate finds the sewer line, and the Town's permit rules are checked.
- 3
Prepare the work area
Pits or the trench are laid out, with sprinklers, trees and the driveway noted.
- 4
Install the new line
New pipe goes in at a continuous slope and is connected at the house and at the main.
- 5
Test and restore
The line is camera-checked or tested, the pit or trench is backfilled, and the surface is restored.
Ask what the Town requires for the connection at the main and who inspects it. Get the answer in writing before the work is scheduled.
Windsor rules that shape a sewer line replacement
The Town requires a building permit to install or move plumbing, even when the owner does the work, and it requires service providers to notify it of work in the sanitary sewer system. Plumbing work also follows the Colorado Plumbing Code, which builds on the International Plumbing Code (IPC). Call Town Hall at 970-674-2400 before the project is scheduled to confirm what applies to your address.
Colorado requires a call to 811 at least two business days before digging. 811 marks public utilities and not your private sewer line, so a private locate is usually part of the plan.
On the Larimer County side of Windsor the Town provides storm sewer only, so the sewer arrangement can differ from the Town's. Confirm that before you compare bids.
Frost depth is the other local number. The Town's code sets the frost line at 30 inches, and buried lines normally sit below that depth.
Repair or replace: a decision test
Repair or line when
- Damage is limited to one or two sections
- The pipe is otherwise sound on camera
- There are no long sags or collapses
- The line is a modern material
Replace when
- Damage runs along much of the line
- The pipe has collapsed or is Orangeburg
- A long sag holds water
- Repairs have repeated in the same line
What drives the price of a new sewer line
Replacement is often one of the larger plumbing costs a house sees. Get the scope in writing, and compare bids against the same camera footage.
A covered, sudden cause may be partly covered by some policies, while wear and root damage commonly are not. Ask your agent before the work starts, not after.
Sewer line replacement questions from Windsor homeowners
Trenchless jobs often finish in a day or two, and open-trench jobs take longer, plus restoration. The length of the line and the surface above it decide, and the quote should say.
For part of the job, yes. The line is out of service while the new pipe is connected, and the schedule should tell you how long. Plan for a short period without water use in the house.
Camera footage is the proof. Ask to see it, and ask for the repair price next to the replacement price so the comparison is fair.
Plumbing work needs a Town building permit, and inspections are handled by the Town's contractor, SAFEbuilt. Ask what applies to your project before it starts.
A line that is backing up is cleared first if possible, which is the job of drain cleaning, and replacement is then planned. The line is answered 24/7 for that first step.
Yes, along with Severance, Timnath and Johnstown. Greeley has its own page, and the same 24/7 line covers the area.
