How Much Does Sewer Line Replacement Cost in Pennsylvania?
Most homeowners pay $1,388 to $5,323 to replace a sewer line, according to a national cost guide updated in August 2026. That guide puts the average at $3,319. A second guide, updated in June 2026, lists $1,423 to $5,775 for the job and an average of $3,478. Both price new pipe at about $50 to $250 per linear foot.
These are national market numbers, not our price list. Around Milford the price moves with the length and depth of the run, rock ledge and where the line goes. Opening a town street adds to it.
What does sewer line replacement cost per foot?
The August 2026 guide prices a new sewer line at $50 to $250 per linear foot, materials and labor included. Its average is $150 per foot. The June 2026 guide splits that into pipe at $3 to $80 per foot and labor at $30 to $200 per foot. Excavation alone runs $50 to $200 per linear foot in the August guide.

Sawkill Environmental handles sewer line repair and lateral replacement by open trench around Milford. We dig from the spot your plumber’s camera marked, pull out the bad pipe and lay new pipe on a graded stone bed. We run our own excavators and equipment.
What does a sewer line repair cost compared to replacement?
The August 2026 guide puts common sewer line repairs, for a clog, tree roots or a collapsed section, at $80 to $1,000. A cracked pipe spot repair runs $600 to $1,050 in the same guide. For replacement, it lists a partial replacement at about $50 per linear foot and a complete replacement at $60 to $250 per foot.
A repair makes sense when one crushed or offset spot sits in otherwise sound pipe. That means a short trench and one new section. Old clay tile with roots at many joints is a different job, and so is a line that has settled into a low spot. In those cases a full replacement lasts longer than chasing one break at a time.
The guides also price trenchless lining at $60 to $250 per foot. That is a plumbing trade with its own tools. We do open trench work: the ground comes up, the pipe comes out, and new pipe goes in where you can see it.
Does the line run to a septic tank or a sewer main?
Around Milford, usually a septic tank. The 2021 Eastern Pike County sewage plan found no central sewer in Milford Borough or Milford Township, and none in Matamoras. Only part of Westfall Township has public sewer. It counted about 2,115 homes on on-lot systems across that study area. So the “sewer line” at most houses here is the building sewer, the pipe from the house to the septic tank. Our septic vs sewer guide covers how to tell which one a house has.
Pennsylvania’s on-lot rules cover that pipe. Under 25 Pa. Code 73.21, a building sewer carrying 1,000 gallons a day or less, which covers a typical home, must be at least 3 inches across. Local plumbing or building codes can set a different size. It needs a cleanout where it leaves the house and every 100 feet after that. The grade has to be at least 1/8 inch per foot. The last 10 feet into the tank may not drop faster than 1/4 inch per foot. Bends ahead of the tank are held to 45 degrees where possible, and the joints must be watertight. If the tank or the absorption area is the real problem, that is septic system repair. Our repair or replacement guide covers the signs.
Where public sewer exists, the pipe is a lateral, and it belongs to the owner. Port Jervis has a city sewer system. Its code puts the cost of the street lateral, from the main to the property line, on the property owner. The owner also maintains, repairs or replaces the building and street lateral as needed. Opening into a public sewer takes a written permit from the city first. Other towns write it differently, so check with your borough or city office.
In July 2026, federal funding was announced for the Eastern Pike County Sewer Extension, which will extend wastewater service to Matamoras and Milford Boroughs. Once a main reaches a street, each house needs its own lateral. The June 2026 guide puts switching from a septic system to a city sewer at around $6,000 or more. It lists a city water and sewer hookup at $500 to $20,000, depending on local rules.
What makes a sewer line cost more in Pike County?
Rock. The US Geological Survey reports that the glacial till in Pike County is typically thin, less than 6 feet thick, and bedrock is exposed at the surface in many areas. A trench that reaches ledge turns into rock breaking, and that is measured in machine hours. Our excavation cost guide covers what rock work adds.
Depth and length. Every guide prices by the foot, and a deep trench moves more dirt per foot than a shallow one. A long run from a house set far back from the road costs more than a short one.
The street. A lateral that crosses a public road means a street opening permit and paving to put back. Port Jervis requires public property disturbed by the work to be restored, and Westfall Township requires a permit to open any township street.
Roots and old pipe. Clay tile comes apart at the joints, and roots follow the water in. Cast iron rusts thin from the inside. One bad joint is a repair. Roots in every joint is a replacement.
Access and the yard. Tight side yards, decks and trees slow the machine. Putting the lawn back ranges from $1,200 to $6,200 in the June 2026 guide, and that line is easy to forget when comparing estimates.
Do you need a permit and an 811 call?
Yes to 811, every time. Pennsylvania law requires notice to PA One Call not less than three nor more than ten business days before excavation begins. Dig Safely New York and New Jersey One Call cover the other two states. The marks show gas, electric, water and cable before the bucket goes in.
Permits depend on where the pipe goes. A connection to a public sewer takes a permit from the city or authority. Opening a town street takes a street permit. On the septic side, the township sewage enforcement officer decides whether the work touches the tank or absorption area, and under 25 Pa. Code 72.22 a repair or replacement of a treatment tank needs a permit. This is general information, not legal advice, so call the township office first.
