Mesquite's sewer rules draw the line at the right-of-way or the sewer easement. Everything from that boundary to your house, including the pipe that runs under the slab, is yours to maintain. With about four in ten Mesquite homes built before 1980, plenty of those private lines are still the originals. We replace them with new PVC at published prices and tunnel under the foundation so your floors stay where they are.

Who owns which part of a Mesquite sewer line
The City of Mesquite's utility ordinance (Ordinance No. 4599, Section 16-45) splits the sewer service in two. The City maintains the sanitary sewer service inside the City right-of-way or sewer easement. The property owner maintains it from the edge of that right-of-way or easement to the structure.
- Inside the right-of-way or sewer easement: the City's side, maintained by the City's Sewer Division.
- From that boundary to your foundation: your lateral. This is the section homeowners usually hire us to replace.
- Under the slab: also yours, and usually the most expensive part, which is why we tunnel instead of breaking floors.
The same ordinance says an owner installs the lateral at the owner's expense under City-adopted building codes, subject to inspection by the City Building Inspection Division. A new lateral has to pass that inspection, so we plan the job around it from the start.
The City's side of the system
Mesquite's Sewer Division operates and maintains more than 475 miles of sewer pipe, 5,611 manholes and 5 lift stations, and wastewater is treated at the South Mesquite Wastewater Treatment Plant operated by the North Texas Municipal Water District. The City uses camera inspection and jet/vacuum cleaning on its mains. If a main is the problem, that work is the City's. If the blockage is in your lateral, it's a job for a plumber.
How old is the sewer pipe under a Mesquite home?
The Census Bureau's American Community Survey (2020–2024 5-year estimates) counts about 54,000 housing units in Mesquite, with a median year built of 1983. About 40% were built before 1980, and about one in four before 1970.
- Original drains in 1960s and 1970s houses are getting old. InterNACHI's life-expectancy chart puts below-ground cast iron waste pipe at 50 to 60 years. A Mesquite house built in the 1960s or early 1970s that still has original cast iron under it is at or near that range.
- Cast iron wears from the inside. The American Society of Home Inspectors notes that cast iron rusts from the inside, so evidence of a failing pipe usually isn't visible until the drain starts backing up.
Signs your Mesquite sewer line needs replacing
- The main line has been cleared two or more times in 12 months.
- Toilets bubble or the tub gurgles when the washer drains.
- Water backs up first at the lowest drain, often a shower or floor drain.
- A camera shows roots in the pipe, a sag that holds water, offset joints, or cast iron worn through along the bottom.
- A soggy, sunken or extra-green strip appears over the line in the yard.
Clay soil and sewer joints
Mesquite sits mostly in Dallas County, with a portion in Kaufman County. A U.S. Department of Agriculture soil survey of Dallas County names Houston black clay as the county's most extensive soil type, and the Texas Water Development Board describes Houston Black soils as classic clays that shrink and swell markedly with changes in moisture. Ground that moves takes the pipe with it, which is how older sewer lines develop sags and separated joints. If your foundation has been leveled, tell us; that work can stress a drain line under the slab.
How we replace a Mesquite sewer line
- Camera the line from a cleanout and mark its path on the surface. You keep the video. See sewer camera inspection.
- Write an itemized quote: feet of tunnel, feet of trench and number of access holes, each at our published price. We don't bill by the hour.
- Have utilities marked and set the job up as permitted and inspected work where the city requires it.
- Tunnel under the foundation from outside so floors, cabinets and tile stay put, then trench the yard run out to the City's boundary.
- Lay new PVC, add a two-way cleanout near the house, test the line for inspection, and backfill the tunnel in compacted layers so the slab stays supported.
When the old yard pipe still holds its shape and the route is clear, trenchless pipe bursting can replace that section without a full-length trench.

Mesquite sewer line replacement FAQs
Who is responsible for the sewer line at my Mesquite house?
Under Section 16-45 of Mesquite's utility ordinance, the City maintains the sewer service inside the City right-of-way or sewer easement. The owner maintains it from that boundary to the house, including any pipe under the slab.
How much does sewer line replacement cost in Mesquite?
Tunneling under the slab is $3,375 minimum for the first 5 ft, then $425 per foot. Open trenching in the yard is $180 per foot, and each access hole is $1,150. Your total goes in a written quote after a camera inspection, and every job starts with a $29 service fee.
Does the City inspect a new sewer lateral in Mesquite?
Yes. Mesquite's ordinance says the owner installs the lateral under City-adopted building codes, subject to inspection by the City Building Inspection Division. We build the new line to be ready for that inspection.
Will you have to break up my floors?
Usually not. We tunnel under the foundation from outside, so floors, cabinets and tile stay in place. Sometimes a small indoor access hole costs less, and when it does we show you both prices.
Is pipe bursting an option in Mesquite?
On the yard section, often yes, if the old pipe still holds its shape and the route is open. Under the slab we tunnel. We'll tell you which method fits after the camera inspection.
How long does a sewer line last?
InterNACHI's life-expectancy chart puts below-ground cast iron waste pipe at 50 to 60 years. Clay soil movement and roots can shorten that. A camera inspection shows the actual condition of your line.
