Portland's residential sewer infrastructure is among the oldest on the West Coast. Approximately one-third of the city's 2,500 miles of sewer pipe is over 80 years old, consisting of brittle vitrified clay, unreinforced concrete, or short-lived bituminous fiber (Orangeburg) piping. Over decades, ground settling, heavy rainfall, and vigorous tree roots compromise these fragile pipe joints, leading to cracked pipe bellies, severe blockages, and sinkholes.
At United Plumbing PDX, we specialize in trenchless sewer replacement methods that eliminate the need to dig destructive trenches across your lawn, garden, or driveway. Using state-of-the-art hydraulic pipe bursting and cured-in-place pipe (CIPP) lining, we replace your failing sewer lateral with seamless, root-proof HDPE pipe that lasts for generations.

Trenchless Pipe Bursting Explained
Trenchless pipe bursting requires only two small access pits: one near the home's exterior foundation and one at the property line near the city sewer connection. A heavy steel cable is fed through the old damaged pipe and attached to a conical hardened-steel bursting head.
As powerful hydraulic winches pull the bursting head forward, it shatters the brittle old clay or cast-iron pipe, pushing the fragments outward into the surrounding soil. Simultaneously, it pulls a brand-new, seamless high-density polyethylene (HDPE) pipe directly into the vacated channel behind it.
The result is a perfectly smooth, leak-proof sewer line with zero joints for tree roots to ever penetrate, installed with minimal landscape disruption.
City of Portland Environmental Services (BES) Cleanout Requirements
Portland plumbing regulations mandate the installation of a dual-directional exterior sewer cleanout whenever a sewer lateral is repaired or replaced. This ground-level access port allows future camera scopes and hydro-jetting equipment to be inserted in both directions—back toward the house and forward toward the municipal sewer main—without tracking hoses through living areas.
Transparent Pricing & Cost Factors
Sewer replacement pricing depends on line depth (shallow 3-ft crawlspace runs vs. 12-ft deep street connections), linear footage, surface paving restoration, and city right-of-way permit fees.
- Depth and total length of the sewer lateral from foundation to city main
- Method of replacement (non-invasive trenchless pipe bursting vs. open trench excavation)
- Pavement and concrete cutting requirements (driveways, sidewalks, or street right-of-way)
- City of Portland Bureau of Environmental Services (BES) permit and inspection fees

Frequently Asked Questions
How long does a trenchless sewer replacement take?
Most residential trenchless pipe bursting projects are completed in just 1 to 2 days, with your water and sewer service operational again by the end of the first afternoon.
Will trenchless replacement destroy my landscaping or driveway?
No. Unlike traditional excavation which tears up your entire lawn from house to street, trenchless pipe bursting only requires two compact access holes (typically 4x4 feet), saving thousands of dollars in hardscaping and garden restoration.
Who is responsible for the sewer line under the street in Portland?
In Portland, homeowners are typically responsible for maintaining the sewer lateral from their home all the way to the connection with the municipal sewer main, including the portion running beneath the public sidewalk and street curb.
What is the difference between trenchless pipe bursting and epoxy CIPP relining?
Pipe bursting hydraulically shatters the old pipe while pulling an identical or larger diameter brand-new solid HDPE pipe through the tunnel. CIPP epoxy relining inflates a resin-impregnated felt tube inside the host pipe. Bursting is preferred when the old pipe has collapsed or shifted off-grade, whereas relining is ideal when the original pipe structure is intact but suffering from root intrusion or hairline cracks.
Do you handle city permitting with Portland Bureau of Environmental Services?
Yes. United Plumbing PDX manages the entire permitting lifecycle, including City of Portland BES plan submittals, right-of-way street work permits, call-before-you-dig 811 locates, and scheduling the final municipal plumbing inspector sign-off.
