Backups that keep coming back
A main line that needs cabling every few months usually has open joints, a crack or a sag holding debris. Cleaning treats the symptom.

Who owns the sewer line in Covina: lateral, City main and LACSD trunk
The property owner owns and maintains the sewer lateral all the way to the public main. The City of Covina owns the local mains, and the Los Angeles County Sanitation Districts own the large trunk sewers those mains feed.
The City of Covina Public Works Department says homeowners are responsible for maintaining the house connection to the sanitary sewer, and that this includes the surrounding environment, such as nearby trees and their roots. The City's Tree Roots and Sewer Laterals handout spells it out. The owner maintains the lateral from the home to the main sewer line, which is usually in the street. That includes the section under the roadway, the parkway tree and the sidewalk in the City right-of-way. The owner's responsibility ends at the main.
That last point surprises a lot of Covina owners. The pipe under the sidewalk and the street is still yours, even though it is on public land. If it cracks under the curb, the repair is a private job.
| Part | Who owns it | What it is | Who to call |
|---|---|---|---|
| Private sewer lateral | Property owner | The pipe from the house to the City main, including the part under the parkway, sidewalk and street | A licensed plumber |
| Local sewer main | City of Covina | The pipe under the street that collects laterals from the block | Public Works, 626-384-5220 |
| Trunk sewer | Los Angeles County Sanitation Districts | Large regional pipes that carry flow from City mains toward treatment | LACSD, through Public Works if unsure |
LACSD is working on its own pipes in the area. In July 2024 the Districts filed a state environmental notice for the District 22 Trunk Sewers Group 4 Rehabilitation Project. It covers about 20,736 feet of corroded 10-inch to 24-inch trunk sewers in Azusa, Covina, Irwindale, San Dimas and West Covina, to be lined with cured-in-place pipe, plus protective coating on 92 manholes. That work is on public trunk lines. It does not touch private laterals, and it does not change who pays for yours.

Signs your sewer lateral needs more than cleaning
Repeat backups, sewage smells in the yard, soggy or sunken ground over the line, and roots that return within months all point to a lateral that needs repair rather than another cleaning.
Roots back within a year
Fast root regrowth means the roots have a wide opening. The City's handout notes that even a small leak lets fine roots in.
Wet or sunken ground
A soggy strip of lawn, a dip in the yard, or extra-green grass along the line can mean sewage is leaking into the soil.
Sewer smell outside
A steady sewage odor near the cleanout or along the path to the street often comes from a broken section.
Gurgling and slow drains
When every drain is a little slow and toilets gurgle, the lateral may be partly blocked by a sag or offset joint.
Camera findings
Video showing cracks, broken pieces, offset joints, standing water or crushed pipe is the clearest sign of all.
If you are not sure whether you have a cleaning problem or a repair problem, start with our drain cleaning page. A clog in a sound pipe is a cleaning job. The rest of this page is for laterals that are failing.
Sewer camera inspection: what it shows and why it comes first
A sewer camera inspection records the inside of your lateral on video, showing the pipe material, its condition, and the exact distance to every root, crack or sag, so repair is priced on facts.
The plumber feeds a waterproof camera on a push cable through a cleanout and records the full run to the City main. A counter on the screen marks the distance. Many camera heads also carry a locator, so the plumber can stand in the yard and mark the spot on the ground above a defect, and estimate its depth.
Covina's housing is old enough that we expect to find older pipe. The City's 2024 Housing Element estimates that about two-thirds of homes were built before 1970, and code enforcement estimates about 30% of homes need some repair. Laterals from those decades were usually clay, sometimes cast iron, and often a mix of materials where earlier owners made repairs.
| Finding | What it looks like | Usual next step |
|---|---|---|
| Root intrusion at joints | Hair-like roots or a dense mat at the pipe joints | Cut and jet; repair or line if many joints are affected |
| Offset joint | One pipe section sitting higher or lower than the next | Spot repair or lining, depending on how many |
| Crack or fracture | Lines running along or around the pipe | Spot repair or lining |
| Sag (belly) | Standing water in a section of pipe | Excavate and re-bed that section; lining does not fix a sag |
| Broken or missing pipe | Soil visible, pieces of pipe missing | Excavated repair or replacement |
| Heavy scale in cast iron | Rough, built-up walls, often on the bottom | Descale and assess; replace if the wall is thin |
| Grease buildup | A coating along the pipe wall | Hydro jetting |
Sewer line repair options: spot repair, lining and replacement
The three main ways to fix a damaged lateral are a spot repair of one section, trenchless lining of the existing pipe, and full replacement, and the camera video decides which one fits.
Spot repair
- Dig at the damaged spot and replace that section
- Good when the rest of the lateral is sound
- Fixes a sag, a broken piece or one bad joint
- Leaves the rest of the old pipe in place
- Angi lists spot repair of a cracked pipe at $600 to $1,050
Trenchless lining (CIPP)
- A resin-soaked liner is cured inside the old pipe
- Seals cracks and joints roots use, with little digging
- Needs a cleaned, jetted pipe that still holds its shape
- Will not fix a sag or a collapsed section
- Angi lists lining at $90 to $250 per linear foot
Full replacement
- New pipe for the whole lateral, by trench or pipe bursting
- Best for broken, crushed or badly sagging lines
- Replaces every joint at once
- Most digging, especially under the street
- Angi lists $60 to $250 per linear foot

Lining is the same basic method LACSD chose for its corroded trunk sewers in the Group 4 project: a cured-in-place liner inside the old pipe. For a private lateral, it is a good fit when the pipe is cracked or rooted but still round and on grade. If the camera shows standing water in a sag, a liner just copies the sag, and that section needs digging.
Many Covina laterals end up with a mix: a spot repair at a sag near the house and lining for the rest. We price each option in writing so you can compare them side by side.
Mature trees and your lateral: what the City will and will not do
The City of Covina will not remove a parkway tree solely because its roots are in your lateral, so the fix is to seal or replace the pipe the roots are entering.
Covina's handout explains the process in plain terms. Roots usually grow around a sound lateral. A leak, even a small one, lets fine roots in. Once inside, they grow fast on the water and nutrients and can block the line. The City's position is that the owner should keep the lateral sound enough to keep roots out.
For an owner, that means a choice between maintenance and repair:
- Maintenance: cut and jet the roots on a schedule. It works, but the roots return, and every visit costs money.
- Repair: line or replace the rooted joints so roots have no way in. More cost up front, fewer calls after.
Do not cut or damage a parkway tree yourself. Ask Public Works at 626-384-5220 before any work near a City tree or in the right-of-way. Our sewer lateral guide covers the City's rule in more detail.
Buying a home in Covina: camera the sewer line first
Get a sewer camera inspection before you close on any older Covina home, because the lateral is yours to repair once you own it and a standard home inspection usually does not look inside it.
Census figures for 2019 to 2023 put Covina's median home value at $666,000. A sewer lateral repair is a small share of that, but it is a cost the buyer takes on with the keys. In a city where about two-thirds of homes predate 1970, the odds of finding an old clay or cast iron lateral are high.
- Book the camera during your inspection period, not after.
- Ask that the run go all the way to the City main, not just a few feet past the house.
- Get the video file and a written summary of each finding with its distance.
- If the house has no outside cleanout, ask about access before the appointment.
- Ask for written repair options and price ranges you can bring to the negotiation.
- Check whether the house is in the City or in unincorporated Charter Oak, since the rules differ.
Sellers can do the same before listing. A clean video is a selling point. A known problem priced in writing is easier to negotiate than one a buyer's inspector finds late. Our Covina 91724 page and the other area pages describe housing and plumbing patterns by neighborhood.
Sewer repair permits in Covina
Sewer lateral repair and replacement is plumbing work, and City of Covina Handout #14 says plumbing work requires a permit, with no work concealed before inspection.
- Where
- Building and Safety, 125 E College St, 626-384-5460
- Hours
- Monday to Thursday, 7 a.m. to 6 p.m., closed 1 to 2 p.m.
- How
- In person at the counter; most permits are issued over the counter while you wait
- Inspections
- Requested by email
- Before backfill
- No work may be covered before inspection
The City has no online permit portal, so the contractor or owner-builder goes to the counter. If the repair is in the parkway, sidewalk or street, ask Public Works at 626-384-5220 what is needed for work in the right-of-way before scheduling. Call 811 at least two business days before any digging so buried utilities are marked.
For work in Charter Oak, County rules apply instead. Our Covina permit guide walks through the counter visit step by step.

Questions Covina homeowners ask
Who is responsible for the sewer line between my house and the street in Covina?
The property owner is. The City of Covina says the owner maintains the sewer lateral from the house to the main, usually in the street, including the part under the parkway, sidewalk and roadway, and any tree roots in it. The City maintains its mains, and LACSD owns the large trunk sewers.
Will the City of Covina remove a tree whose roots are in my sewer line?
No. The City's Tree Roots and Sewer Laterals handout says it will not remove parkway trees solely because their roots are in a lateral. The owner's fix is to keep the pipe sound, usually by lining or replacing the joints the roots are entering. Ask Public Works before any work near a City tree.
How do I know if my sewer line is broken?
Repeat backups, roots returning within months, a sewage smell in the yard, and wet or sunken ground over the line are the common signs. A camera inspection confirms it by showing cracks, offset joints, sags or missing pipe, with the distance to each one.
How much does sewer line repair cost in Covina?
Angi's 2026 data puts sewer line replacement at $1,388 to $5,323 in the normal range, $60 to $250 per foot, and spot repairs at $600 to $1,050. Length, depth, permits and work under the street move the price. Call (626) 746-1970 for an exact quote.
Should I get a sewer camera inspection before buying a house in Covina?
Yes, especially for an older home. About two-thirds of Covina homes were built before 1970, the lateral becomes the buyer's to maintain, and a standard home inspection usually does not look inside it. Book the camera during your inspection period and keep the video.
Do I need a permit to repair my sewer line in Covina?
Yes. City of Covina Handout #14 says plumbing work requires a permit and no work may be concealed before inspection. Permits are issued in person at Building and Safety, 125 E College St. For work in the street or parkway, ask Public Works what else is needed.
Is trenchless sewer lining worth it?
It is when the pipe is cracked or rooted but still round and on grade, because it seals joints with little digging. It does not fix a sag or a collapsed section. Angi lists lining at $90 to $250 per linear foot. The camera video tells you if your lateral is a candidate.
Does the LACSD sewer project in Covina fix my lateral?
No. The Los Angeles County Sanitation Districts' District 22 Group 4 project lines about 20,736 feet of public trunk sewers in Covina and nearby cities. It does not include private laterals. Your lateral remains the owner's responsibility under City rules.
