Sewer Line Replacement Cost


How Much Does Sewer Line Replacement Cost?

 
average costTraditional Process: $50-$250+ per foothigh costTrenchless Process: $60-$250+ per foot
post E-mail post Post   Comments (62)
  Typical costs:
  • The traditional dig-up-and-replace method requires excavating a long, deep trench or trenches to remove the old pipes and install new ones. This method can cost $50-$250 or more a foot, depending on the length and depth of the existing pipes, local rates and the ease of access. Replacing an average sewer line from the house to where it connects to the public sewer system typically costs $3,000-$6,000. However, if the project is complex and/or if the connection to the public system is in the middle of the street it can cost $7,000-$25,000 or more. CostHelper readers report paying $4,500-$13,000, or $50-$100 per foot traditional replacement of 50'-100' of sewer line, for an average cost of $7,493 or $106 per foot.
  • Trenchless sewer replacement uses minimal digging with one of several methods -- pipe-bursting, in which a machine breaks and pushes out the old pipe while pulling through and installing a new pipe in its place. Expect to pay about $60-$200 per foot, or $3,500-$20,000 for an average household sewer line depending on the type, length and depth of the existing pipe, plus the cost of any required permits or sidewalk repairs. The trenchless slip-lining method (in which a new, smaller-diameter is installed inside the existing sewer line) or relining (both of which reduce the overall interior diameter of the sewer line) typically cost $80-$250 or more a foot, or $4,000-$25,000 or more for a typical household sewer. CostHelper readers report paying $6,000-$12,000 or about $92-$238 per foot for trenchless sewer repair, with an average cost of $8,900 ($162 per foot).
  • Smaller projects generally cost more per foot. To replace sewer lines less than 50' long, CostHelper readers paid $5,500-$6,800 or $148-$550 per foot for traditional trenching projects, at an average cost of $6,167 or $232 per foot.

What should be included:
  • Traditional dig-and-replace sewer work can require a lot of invasive excavation and result in a patched-up yard, but can be a relatively simple project; an excavator digs up the old pipes, new ones are installed and the trench is refilled. A California plumber provides a video of replacing old clay piping using traditional methods[1] .
  • Trenchless methods are usually faster than the traditional approach, but require at least some digging, usually at each end of the existing pipe and anywhere in-between where it bends or turns. A video by the manufacturer US Trenchless illustrates the pipe-bursting process[2] while one by a New Hampshire plumbing company explains sewer pipe relining[3] .
  • Sewer pipe installation or replacement generally requires a permit; check with the local building department or make sure the contractor is handling all needed government approvals and paperwork.
Additional costs:
  • Many companies first do a video camera inspection of the pipes at a cost of $100-$800 but with an average price of $250-$550, depending on local rates and the total length of the pipes; often this amount will be deducted from the final bill if the same contractor replaces the sewer line.
  • Ask detailed questions about what condition the yard will be in when the project is completed. Replacing (lawn, trees, shrubs, flower beds) displaced or damaged by traditional trench digging can cost $50-$5,000 or more, depending on how much is involved.
Shopping for sewer line replacement:
  • Replacing a private sewer line can be done by a plumber, sewer contractor or general contractor; get a variety of quotes because they may differ in both price and available equipment. The City of Portland, OR, provides an overview for installing a private sewer line[4] .
  • Check with the sewer department to see if it maintains a list of local contractors or, for larger projects, search for local members of the Plumbing Heating Cooling Contractors Association[5] .
  • Ask about training and experience; request (and check) references; confirm that the company is properly bonded, insured and licensed[6] ; and see if there are any complaints with the Better Business Bureau[7] .
  • Request a detailed bid (not just an estimate) in writing, clearly describing all the work to be done and the materials to be used, who is paying for and obtaining required building permits, the total price for the project and the estimated start and finish dates.

Never had major plumbing issues once every three years it backs up this time I called my neighbor who is a licensed plumber to take a look at it he first quoted us $35OO he'd have it done in a day he had all the fancy tools camera, locater after digging and breaking the clay pipe and going in to clear the line then ran the camera again to let us know that the roots were cutting into the lateral that ran into the street and if it ever did bust we are looking at thousands upon thousands of dollars of repair work since the city would need to get involved and we'd need to get permits and city inspectors well after his spiel said we’d need to get a liner from the clog point to the street since it was also misaligned were it linked up to the city’s line he then said that would be another $11,500 on top of the $3,500 I nearly passed out I was in tears in shock I didn’t even know what to do but cry he saw me tear up and said he’d try and cut us a better deal on the liner so he made a call and

Main Sewer Line Replacement
Amount: $2,989.00
Posted by: roro in Little Rock, AR.Posted: April 11th, 2017 07:04PM
Type: ReplacementLength: 70\'
Little Rock offers a sewer line replacement program for owners with Old Orangeburg pipes. They will pay up to $2,500 to replace if you qualify. You must pay $400 street cut to the city plus cost to plumber to replace or do it yourself and get reimbursed. So total cost to me should be about $900 if all goes as expected once I receive refund.

Type: plastic pvc 4" lineLength: about 35-40'
In 2005 I was living in Colorado Springs and experienced a sewerage back-up and had to replace my sewer line because of clogged invasive roots in the cracked sewer line preventing proper drainage. Rotorooter was employed with no luck; could not break through the roots. City permit was very expensive ($6,000.00)to cut into and repair the street. Took three days.

partial sewer line replacement
Amount: $5,800.00
Posted by: unhappy camper in santa cruz, CA.Posted: February 25th, 2017 04:02PM
Type: PVCLength: 15 ft.
i was quoted (verbal only) $2,500 and waited 3 weeks for the plumber to schedule my job. the old ceramic pipe was about 3' deep, running under a recent copper water pipe and alongside a birch tree with 2 large roots crossing above it that were excised (and will likely kill the tree). excavation took 2 unskilled workers a couple of hours. a clean-out was installed in the replacement section, sticking up 10" above the ground in the center of my flat, postage-stamp yard. a shrub was removed unnecessarily and no clean-up was performed. i am an older single woman and i feel ripped off! the entire job took 5.5 hours. afterward, i spent 2 hours cleaning the cobbled driveway and strategically re-installing the shrub to conceal the clean-out eyesore (although the shrub is also likely a goner). i was offered a $600 discount for paying in cash and waiving an invoice or receipt. which means i am paying $600 for the home repairs deduction on my 2017 taxes.

Broken drain line replacment
Amount: $7,600.00
Posted by: #IFEELTAKEN in Baton Rouge, LA.Posted: February 13th, 2017 01:02PM
Type: PVCLength: 20 feet
After Roto-Rooter inspected the drain line which could not get passed 35 feet from the cleanout, serviceman suggested for a new cleanout to be installed near the area where the camera could not pass, this at a cost of $1,450. Once they broke up the cement and dug in about 2 feet they realized the old tar-rolled pipe had collapsed.
Since this had to be repaired they gave me an estimate of $8,500 to breakup the length of the drive (about 70 feet), lay down new PVC (quarter inch think), install a new cleanout and poor cement back on the drive. After further analysis we decided to tie into a newer drain line from an in-laws suit cutting the cement breakup and poor from 70+ feet to only 20 feet and the PVC pipe from 80+ feet to 20 feet. With these reductions I imagined my cost would go down by at least 40 percent of the $8,500 initial estimate but the serviceman stood his ground and said the best he could do is $7,600. I feel this repair should not been more than $4600.

Trenchless sewer line replacement

Type: Replace sewer line from house to city'sLength: 80'
Had several plumbers clean out line over 16 months but back-up recurred several times. Finally called Rotorooter and a nice young man came to house at 11:00pm to clean out so we could use bathrooms. Next day a cameraman came to inspect entire line. Within 2 days the 40 year old cast iron line was replaced and all is working well. The workers were excellent and did as little damage as possible to our front yard. Could not be happier that this company solved an annoying problem so quickly that other plumbers failed to do. Could not be happier!

Lateral Sewer Line Replacement
Amount: $5,500.00
Posted by: Mr Proactive in San Francisco, CA.Posted: September 20th, 2016 01:09PM
Type: Replacement -Cast IronLength: 30
Replaced 80 year old clay lateral with 4 inch diam. cast iron. Trench was 5 feet deep at the main sewer line connection. Installed two new clean outs and brought up to code. Witnessed too many neighbors paying $8K + to replace theirs, so I spent some time researching and got a company to do it for $5K. I thought I'd be proactive and just get it done before it fails. There was no rush so I was able to get a good price.

Type: OrangeburgLength: 70 feet
Home built 1953. No problems until this year when sewage backed up into bathtub. Roto Rooter unclogged with blow bag. Then, 6 weeks later, couldn't get beyond obstruction at 25 feet. We then went with a different plumbing firm, deciding to replace the line up to the obstruction but upon excavation discovered we were a victim of an Orangeburg installation. And that the original contractor had tied the stormwater drain into sewer line. So we replaced everything with 4 inch ABS. This new installation included an outside access cleanout which we didn't have before.

Type: clay broken pipesLength: 50
I hope someone out there can help me! I have 2 main questions. I need to start this work as soon as possible.
1. Does anyone know how to tell where the lateral sewer pipe connects to the street pipe? No one will tell me that they can know. Workers are giving me the impression that they just dig all around to find out. Makes a big difference where it is.
2. How can I find a sample contract or bid to even begin to know what to ask these workers?
I have recently discovered that there is a break and significant misalignment in our lateral sewer pipe. There was a back up that was cleared, but we were told it it was only a matter of time until that small area got blocked again. The break has been located twice with cameras (which did not agree with each other). One said the break is under the sidewalk and one said under the second up of the abutting steps. They were both using transmitters from cameras. We know there are lots of roots in the pipes also.
I have had 2 sewer plumbers,

Trenchless Main Sewer Repair
Amount: $6,900.00
Posted by: Greg Summers in Yorba Linda, CA.Posted: July 6th, 2015 12:07AM
Type: PermaLinerLength: 63
We have had issues since 1998 with main line back ups. Originally it would back up ever 2 years. In 2007 we remodeled our house. At that time we were told that if we wanted to replace our clay line it would cost $ 10,000.00. We had already gone over our initial budget so we held off. Six months later our first back up. Cleared for 150.00. Then every year after that 2-3 times at 50.00 to 100.00 to clear. Fast forward to 2015 3 times in the last 6 months. We had free camera inspections twice with the plumbers telling us they would have to Hydro-jet to clear the all roots at 350.00 we choose just the basis snaking. They warned that our line could collapse if that happened it would cost $11,000.00 to repair. I started researching options. We have a few mature trees that we did want to cut down or destroy our landscape so on July 3rd I hired ProPowerPlumbing. Five guys worked from 2-6 hours each completing the job in one day. We got Perma-Liner with a 50 year transferrable warranty.

Repair of Sewer Line
Amount: $7,265.00
Posted by: Romain Giger in San Jose, CA.Posted: April 15th, 2015 08:04AM
Type: Cement/ABSLength: 2 feet
The break was 5 1/2 feet down. The ground had to be dough out approx. 3 feet wide by 4 feet long
The soil was average and it took the person about 6 hours of digging. The repair took an additional 2 hrs and 1 hr for backfill and cleanup. In addition the line was cleaned and inspected with a
camera. I feel the price of $7,200 was very high. What do you think?????

I live in a mobile home so the sewer line is attached to the bottom of the mobile home. So I don’t know if this falls under trench less etc.. Plumber replaced the whole sewer line at least down to where it starts to go subterranean, also he repiped my kitchen sink plumbing, added a sturdevent stack under the sink which is the code now, and also aimed the water to travel a shorter distance to the main sewer instead of going 25’ longer to hit the sewer line.

Sewer Line Replacement and Lining

Type: Sewer replacement and liningLength: 50\' PVC 50\' Lining
Feet are estimates, but with 30' bellied clay pipe causing frequent backups into the floor drains in the house, we replaced 49' of clay pipe from the edge of our property to the main line with sewer PVC and roughly 50 feet of lining from that mid-point to the inside of the house (just inside the foundation with mostly clay pipe until it transitioned to cast iron sewer pipe under the house). Expensive but worth it as we were tired of augering out the mainlines every 2-3 months.

Bowed line underground did not drain properly to street. Replaced lines in basement too, moving them from below the concrete floor to the basement ceiling level, as the "drop" from the house to the street wasn't sufficient. New trench (pebble-filled to support line) ran from 4 feet down at house to 16 feet down at street connection, so lots of digging. 5 full days of work. 2 men for plumbing (plumber and assistant) plus 2 men for 2 backhoes (one for deep work and one for shallow work close to house.) Note: 10-year home warranty only covers underground problems for 2 years. Negotiated $18,000 price. Plumber had to address cave-in that resulted in electric company replacing broken underground power line. Make sure whoever does the work has insurance and uses caissons for deep digging.

Type: Replaced 5 ft then lined the restLength: 75
I got totally taken from rooter town. I had replaced a 5 ft piece of pipe in the yard and the rest lined. He started out with 3500 for the replacement and once the hole was dug recommended I line the rest as now he discovered it was off on the main. For comparison ithe whole thing dug up, including street should have been about 7k. I would recommend getting estimates and watching for those that start out with saying it is a small job and once the hole is dug tell you you need more and charge outrageously for it. Very unethical.
