Aurora sewer questions, answered fast
Quick answers to what callers ask first, then every sewer question from the rest of the site.
Sewer line repair in Aurora, Colorado
Who owns the sewer line from my Aurora house to the street?
Aurora makes the property owner responsible for the service line from the home to the city main in the alley or right of way, including repairs and resulting damage.
Why does sewage come up in my basement floor drain?
The floor drain is usually the lowest opening, so when the service line is blocked, wastewater backs up there first.
Do I need a backwater valve in Aurora?
Many basement homes benefit from one, especially if the city main has backed up before. A plumber can assess your line.
Can my sewer line be fixed without digging up the whole yard?
Often. Lining or pipe bursting needs only small pits, though sags and some collapses still need excavation.
Why do sewer lines crack in Aurora?
Swelling clay soils, aging clay and cast iron pipe, freeze-thaw near the surface and tree roots all contribute.
Who does the work when I call?
An independent licensed plumber. Your call is connected to them directly. This site does not do the work.
Do I need to call 811 before sewer repairs?
Yes. Colorado requires a call to 811 before excavation so buried utilities are marked.
How do I check a plumber's license in Colorado?
The state's Division of Professions and Occupations has a license lookup. Ask for the license number on the call.
Heather Ridge
Can the association require access to my unit for sewer work?
Governing documents often allow access for shared plumbing. Check your documents.
Should I tell my neighbors about a slow drain?
Yes. If they notice the same thing, the shared line is likely involved.
How often should shared lines be inspected?
Many associations inspect every few years, more often near trees.
Does lining a shared line mean we cannot use water?
Usually for part of a day while the liner cures, with advance notice.
Who fixes a shared sewer line?
Usually the association, according to the community's governing documents.
Why did my unit back up when I didn't use water?
A shared line may be blocked, and neighbors' water reaches your drains first if you are lower.
Can I call a plumber directly?
For drains inside your unit, yes. For shared lines, start with the association.
Do garden-level units need backwater valves?
They can help against main-line surges. Discuss with the association.
Will repairs tear up the lawns?
Trenchless methods often avoid that.
What should I tell the plumber?
Unit type and level, whether neighbors are affected and association contact details.
Hoffman Heights
Is it worth inspecting a line that has never backed up?
In a home this age, many owners do, because problems often build silently until a backup.
Can a cast iron drain under my basement floor be lined?
Often, if it still holds its shape. The camera shows whether it can.
Will repairs disturb my mature trees?
Trenchless methods reduce that. If digging is needed, crews can work to protect major roots.
Do neighbors' repairs tell me anything about my line?
They are a hint, since many lines are the same age, but each line needs its own inspection.
How old are Hoffman Heights sewer lines?
Many date from the 1950s, about seventy years old.
Should I replace or line my line?
The camera decides. Round pipe with roots often suits lining; collapsed or sagging pipe needs replacement.
Why does my basement drain back up?
The service line is likely restricted. Stop water use and call.
Does the historic survey limit repairs?
No. It documents the neighborhood's history but does not restrict sewer work.
Do I need a backwater valve?
It helps against city-side backups, especially with a finished basement.
What should I tell the plumber about my Hoffman Heights home?
Basement layout, finished rooms, trees, past repairs and whether you have had backups.
Original Aurora
Do Original Aurora homes connect to alley mains?
Many do. A camera and locator confirm your route.
Is my sewer line likely clay?
Many original lines are clay, often with later repairs. A camera inspection shows what you have.
Can roots be kept out without removing my trees?
Yes. Lining or replacing the line seals it against roots.
Who is responsible for the line to the alley?
Under Aurora's rules, the property owner, including locating it and any damage from repairs.
Can a line under my garage be repaired without demolishing it?
Often, using trenchless methods with pits outside the garage.
Why does my basement floor drain back up?
The service line is likely restricted by roots or damage. Stop water use and call.
What should I tell the plumber about my Original Aurora home?
Age, basement layout, alley access, big trees and past repairs.
Saddle Rock
Why does my line clog only after big gatherings?
Extra flow and grease can overwhelm a line with a belly or debris.
Can roots ever get into PVC?
Rarely, usually only at damaged fittings or loose cleanouts.
Should I camera the line after buying a newer home?
Many owners do, to catch debris or sags early.
How long does re-bedding a belly take?
Usually a day or two, depending on depth and access.
Can a newer PVC line really have problems?
Yes. Settling, debris and grease cause most of them, even though roots rarely do.
What is a belly in a sewer line?
A low spot where the pipe sank with settling soil, so water and solids collect there.
Can a belly be fixed without replacing the whole line?
Usually. The low section is dug up and re-bedded.
My floor drain is behind finished drywall. Is that a problem?
It makes access harder in an emergency. Keep a panel or opening so it can be reached.
Does the HOA need to approve sewer repairs?
The repair is yours, but landscaping restoration may need to meet association rules.
What should I tell the plumber about my Saddle Rock home?
The year built, whether the basement is finished and what the drains are doing.
Tallyn's Reach
My home is only five years old. Can the line already have a problem?
Yes. Debris and settling can cause trouble early.
Do I need to worry about frost on a deep line?
Deep lines are well below frost; shallow sections or exposed cleanouts matter more.
Can builder plans be wrong about the route?
Sometimes. A locator confirms it.
Does a walkout make backups less likely?
Not necessarily. The lowest drain still overflows first.
Why would a sewer line in a newer home back up?
Usually a clog from grease or wipes, construction debris or a low spot from settling.
Are roots a concern in Tallyn's Reach?
Rarely yet, because trees are young and lines are PVC.
Why is excavation harder here?
Deep basements and sloping lots can put lines deep in the ground.
Do builder plans help?
Yes. They can show the route and depth of the line.
Who is responsible for my sewer line?
The owner, from the house to the main, under city rules.
What should I tell the plumber about my Tallyn's Reach home?
Year built, basement depth, whether it is a walkout and which drains back up.
Village East
Is my home old enough to need a sewer inspection?
At fifty to sixty years, many lines are due for a look, especially with trees nearby.
Can a removed tree still cause sewer problems?
Its decaying roots can catch debris or leave voids that let the pipe settle.
Will a lint trap really help?
It keeps fibers out of the line, which reduces gradual buildup.
Can I keep using the washer if the standpipe overflows?
No. Stop and have the line checked first.
Why does my laundry drain back up before anything else?
In a split-level it is often the lowest drain, so it overflows first when the main line restricts.
Is my Village East line plastic or cast iron?
Homes from this era vary. A camera inspection shows each material along the run.
Can a line under my driveway be fixed without breaking concrete?
Often, with lining or bursting through small pits.
Why is there standing water in my line on camera?
Usually a sag where the soil has settled, which collects solids.
Does my sewer main run in the street or alley?
In Village East it is usually the street. A locator confirms it.
What should I tell the plumber about my split-level?
Which level backs up, where the cleanout is and any earlier repairs.
Sewer backup in the basement
Can a backup damage my furnace?
If sewage reached it, have it checked before running it, especially gas appliances.
How long until I can use the basement again?
Small cleanups may take a day; larger ones need days of drying before rebuilding.
Should I open the basement cleanout?
Not while the line is backed up. Pressure behind the cap can release sewage onto the floor.
Is it safe to stay in the house?
Usually, if the basement is closed off and nobody uses water until the line is cleared.
Why does the floor drain smell even without a backup?
The trap may be dry. Pour water into it.
Will a backwater valve prevent all backups?
It stops backups from the main, not blockages in your own line.
How do I know if it is sewage or groundwater?
Sewage is gray or brown and smells. Clear water in a sump pit or seeping through walls is groundwater.
Can I use the washing machine after the line is cleared?
After the plumber confirms the line is clear and the cause is known.
Sewer smell in the yard
Is a yard sewer smell dangerous?
Mostly unpleasant, but strong odors should be traced and fixed.
Why is it worse in summer?
Heat and cracked soil let odors rise.
Can a snow shovel break a cleanout cap?
Yes, and mowers too.
Could it be the city main?
Yes, especially along alleys.
Can sprinklers cause a wet spot that looks like a sewer leak?
Yes. A leaking sprinkler or water line can soak the lawn too. Sewer leaks smell.
Can a vent cause odors on my deck?
Yes, if it ends close to the deck. Extending or relocating it may help.
Does a sewer smell outside mean a broken line?
Not always. Check caps and vents first; persistent smells near wet spots suggest a leak.
Why does my basement smell like sewer?
Often a dry floor drain trap. Pour water into it. If the smell persists, have the drains checked.
Should I dig to find the leak?
No. Call 811 and have a plumber locate it.
Signs of a broken sewer line
Does one slow drain mean a broken sewer line?
Usually not. One slow drain is typically a local clog.
Why is part of my lawn greener?
A leaking line can feed grass above it.
Can a line leak without a backup?
Yes. Cracks can leak into the soil for a long time.
Do newer homes get broken lines?
Less often, but settling and construction damage happen.
Should I film my line before buying an older home?
It is one of the most useful checks for pre-1980 Aurora homes.
Can sewer problems damage my foundation?
Leaks near the foundation can wet swelling clay and contribute to movement. Have the line checked near the house.
Why does my floor drain gurgle in spring?
Snowmelt can enter cracked lines and raise flow. A camera inspection shows where.
How soon should I act?
Soon. Early signs often come before a basement backup.
Tree roots in the sewer line
Must I remove my tree?
Usually not. Sealing the pipe keeps roots out.
Why do roots come back?
The openings remain after cleaning.
When are roots worst?
Often late summer, in dry weather.
Do newer PVC lines get roots?
Less often, but loose joints can let them in.
Can I cut roots myself with a rental auger?
Rental augers rarely clear a main line root mass and can get stuck. A plumber's equipment and camera are safer.
Can roots come from the city's parkway trees?
Yes. If roots enter at or beyond the connection, the public side may need city attention.
Is lining the best fix for roots?
Often, for round pipe with roots at joints. Broken or sagging pipe may need replacement.
How often should a root-prone line be cleaned?
It varies. If cleaning is needed yearly or more, consider a permanent fix.
Which trees cause trouble?
Elms, ash, maples and cottonwoods are common culprits.
Trenchless vs excavation
Is trenchless always better?
No. It cannot fix sags.
Is winter a problem?
Digging is slower in frozen ground; trenchless needs less digging.
Do both need 811?
Yes.
Which protects trees?
Usually trenchless.
Do I need a permit for either method?
Sewer repairs that involve excavation or replacement often need permits, and both need 811 locates. The plumber handles them.
Which method is faster?
Often trenchless, but short shallow excavations can be quick too.
Will my lawn recover after excavation?
Yes, though clay may settle and need topping up.
Is excavation better for newer PVC lines?
Often a short excavation at the damaged spot is simplest for localized problems in newer lines.
Can trenchless work start from my basement?
Often, if the cleanout gives good access.
Who decides?
The camera findings and the plumber's assessment.
Root Intrusion Removal
How do I know roots are in my line?
Slow drains, gurgling floor drains and repeated backups are common signs. A camera confirms it.
Will roots grow back?
Usually, because the openings remain. Lining or replacement stops regrowth.
Is jetting safe for old clay pipe?
Often, with care. A camera inspection helps decide.
Should I remove the tree?
Usually not. Sealing the pipe solves the problem and keeps the tree.
Which trees cause the most trouble in Aurora?
Mature elms, including Siberian elms, plus ash, maples and cottonwoods are common culprits.
When do root backups happen most?
Often in late summer, when dry conditions push roots toward leaks.
Do root killers work?
They can slow regrowth when used as directed but do not seal openings.
Can the new line be routed around a tree?
Often, if slope and connection points allow it.
What should I tell the plumber about a replacement?
Symptoms, camera findings, what sits over the line and whether the main is in the alley or street.
Should I add an outdoor cleanout?
It makes root cleaning easier and keeps mess out of the basement.
Do creek-side trees cause more root problems?
Often. Cottonwoods and willows near drainageways have vigorous roots.
What if the roots come from a neighbor's tree?
The service line is still the owner's responsibility. Sealing the line fixes it either way.
Can roots reach the drain under my basement floor?
Occasionally. If roots appear near the house on camera, the plumber checks the foundation penetration and the drain under the slab.
Do volunteer trees along my fence matter?
Yes. Fast-growing volunteers like Siberian elms send roots toward sewer leaks. Removing them near the line helps.
Can roots affect a townhome's shared line?
Yes. Associations often manage cleaning and repairs for shared sections.
Will cleaning roots from the basement make a mess?
Plumbers protect the area and manage the flow, but keep children and pets upstairs during the work.
Can roots come from the parkway tree?
Yes. If roots enter at or beyond the city connection, the problem is reported to the city.
What should I tell the plumber about roots?
How often drains slow, where large trees stand, whether the basement drain is involved and any past cleaning.
Are roots in cast iron a bad sign?
Often. Roots plus corrosion suggest the pipe is near the end of its life.
How long does root cleaning last?
It varies by tree, season and pipe condition, from months to a year or more.
Does root cleaning need a permit?
Cleaning does not. Repairs that follow may.
Sewer Backup Cleanup
What should I do first if sewage comes into my basement?
Stop all water use, keep people and pets out and call a plumber. Avoid contact with sewage.
Why does my floor drain overflow when I do laundry?
The washer releases a surge of water that cannot pass a restricted line, so it rises at the lowest drain.
Will a backwater valve stop all backups?
It stops backups from the city main, not blockages in your own service line.
Who pays if the city main caused the backup?
The city handles the main. Claims follow the city's process.
Can I clean up a small backup myself?
Small backups on bare concrete can be cleaned with protective gear. Soaked carpet and drywall need professionals.
Is my furnace safe after a backup?
If sewage reached it, have it checked before running it.
Does insurance cover basement backups?
Many Colorado homeowners policies leave backups out unless an endorsement covers them. Photograph the damage and check your declarations page.
Can a plumber tell me whether the backup came from my line or the city's?
Usually, with a camera inspection after clearing the line, which shows where the blockage was.
Should I move belongings off the basement floor?
Yes. Keeping boxes and furniture off the floor near drains limits damage if a backup happens.
Is water at the floor drain always a sewer backup?
Not always. A dripping water heater relief valve or a sump overflow can also leave water there. Clean water versus sewage is the clue.
How long does it take to dry a basement after a backup?
Small cleanups may take a day; larger ones with carpet and drywall removal often take several days of drying before rebuilding.
Can a basement bathroom back up if the main is clear?
Yes, if it relies on an ejector pump that has failed. Have the pump checked.
Why does my basement smell like sewer gas without a backup?
A dry floor drain trap is the most common cause. Pour water into the drain. If the smell persists, have the drains checked.
Should my sump pump drain into the sewer?
No. It should discharge outside, not into the sanitary sewer.
Sewer Camera Inspection
Where does a plumber put the camera in an Aurora home?
Usually the basement cleanout near the foundation wall, or an outdoor cleanout if there is one. A toilet or roof vent can work if needed.
How long does an inspection take?
Often an hour or two, including access and locating. Clearing a blockage first adds time.
Can a camera see the city's part of the line?
It can usually reach the connection with the main. Public-side problems are reported to Aurora Water.
Will the camera show roots?
Yes. Roots are easy to see on video, from fine hairs at joints to full root masses.
Should I inspect the sewer line before buying a home?
For older homes, it is one of the most useful checks you can add.
Can I get a copy of the video?
Many plumbers provide it. Ask on the call.
My basement is finished. Can the plumber still get in?
Yes, but the cleanout may need to be found or exposed. Mention it when you call.
Can a sewer leak affect my foundation?
A leak near the foundation can wet swelling clay and contribute to movement. A camera can check the line near the house.
Why are Aurora sewer lines so deep?
They are buried below frost and must slope to the main, so depth increases toward the street or alley.
Does a camera inspection require a permit?
The inspection itself does not. Repairs that follow may.
Sewer Line Replacement
How do I know my line needs replacing rather than repairing?
A camera inspection decides it. Collapses, multiple sags and severe corrosion usually mean replacement.
Who is responsible for the line to the main?
In Aurora, the property owner, including locating it and any damage from repairs.
Can the line be replaced without trenching?
Pipe bursting replaces it through two pits if the path and slope are acceptable.
How deep is the trench?
Often several feet, deeper toward the main, because lines are buried below frost.
Can replacement happen in winter?
Yes, but frozen ground slows trenching. Bursting needs less digging.
Will my basement floor be cut?
Only if the building drain under the floor also needs replacing.
Do I need 811?
Yes, before any excavation.
Can the new sewer line be routed around a big tree?
Often, if slope and the connection points allow it. Rerouting protects roots and the tree.
What should I tell the plumber about replacing my line?
The symptoms, any camera findings, what sits over the line and whether your main is in the alley or under the street.
Does insurance cover replacement?
Wear and tear usually is not covered, but some policies or service line plans help. Check yours.
Do newer homes ever need full replacement?
Rarely. Most newer-home problems are localized and fixed with a short excavation.
Should I replace my sewer line before finishing my basement?
If the line or building drain is old and failing, doing it first avoids tearing out new finishes later.
Will my driveway be cut for replacement?
Only if open-trench replacement crosses it. Bursting or rerouting often avoids it.
Is my four-inch line big enough?
For most homes, yes. Homes with added bathrooms or basement apartments should confirm capacity during replacement.
Is spring a bad time to replace a sewer line?
Snowmelt can flood trenches and soften clay. Late spring or early fall is often easier if timing is flexible.
Should I replace the drain under my basement floor at the same time?
If it is old cast iron in poor condition, doing both at once avoids a second project.
Can only part of the line be replaced?
Yes, if the rest of the line is sound on camera.
What pipe is used?
Usually PVC for trenches and HDPE for bursting.
Trenchless Sewer Repair
Can trenchless repair fix a sagging line?
No. Lining and bursting follow the existing path. Sags are fixed by excavating and re-laying that section.
How many pits are needed?
Usually one or two, depending on the method and access. Lining can sometimes start from a basement cleanout.
Can trenchless work be done in winter?
Often yes. Small pits are easier to open in frozen ground than a long trench.
Do roots grow through liners?
A properly installed liner has no joints along its length for roots to enter. Ends must be sealed well.
Will my driveway need to be broken?
Trenchless methods usually avoid it, unless a pit must go there.
Do I need to call 811?
Yes. Any pit requires utility locates first.
Can a liner be installed from my basement?
Often, if the cleanout gives good access and the line is suitable.
Can trenchless work happen with snow on the ground?
Often yes. Pits are small, crews cover them overnight, and lining from a basement cleanout happens indoors, out of the wind, snow and cold of a typical Aurora winter day on the plains.
What should I tell the plumber about trenchless options?
Share the camera video, what sits over the line, and whether the main is in the alley or street.
Is digging ever simpler than trenchless?
For short, shallow lines under open lawn, a small excavation can be quicker.
How long do liners last?
Liners are designed for long service when installed correctly. Ask about the specific system and warranty.
Can trenchless methods avoid my driveway?
Usually. Lining or bursting from pits on either side avoids breaking the slab in most cases.
Will lining work in my basement disrupt the house?
Equipment comes into the utility area for part of the day, with floors protected and ventilation for curing.
Can my basement drains be lined too?
Sometimes, if they are continuous and round. Broken sections under the floor still need to be cut out.
What if the camera shows damage at the city connection?
The plumber documents it, and public-side repairs are coordinated with the city.
Is trenchless repair permanent?
A properly installed liner or burst pipe forms a continuous new line. Ask the plumber about expected service life for your situation.
Quick answers
Fast answers to Aurora's most common sewer questions
Who is responsible for my sewer line in Aurora?
The property owner, from the house to the city main in the alley or right of way, including repairs and resulting damage.
Why did sewage come up through my basement floor drain?
The service line is likely blocked, and the floor drain is the lowest opening, so it overflows first.
Can a sewer line be repaired without trenching my lawn?
Often, with lining or pipe bursting through small pits, though sags need digging.
Do I need to call 811 for sewer work?
Yes, before any digging in Colorado.
What is a backwater valve?
A valve that lets sewage leave the house but closes if flow reverses from the main, protecting basements.
Why do roots get into sewer pipes?
They follow moisture leaking from cracks and old joints, then grow inside.
Are newer Aurora homes safe from sewer problems?
Newer PVC lines resist roots, but settling, construction debris and grease can still cause trouble.
Should I use chemical drain cleaner on a backed-up main line?
No. It rarely clears a main blockage and makes the work hazardous for whoever opens the line.
How deep are Aurora sewer service lines?
Usually several feet, deeper toward the main, partly to stay below frost. A locator measures the depth.
Can freezing weather affect sewer lines?
Deep service lines rarely freeze, but shallow sections, exposed cleanouts and frozen ground can complicate repairs.
Does a camera inspection need a permit?
An inspection alone does not. Repairs that follow may.
Why do drains slow after heavy rain?
Groundwater can enter cracks in the service line, and the city main may be carrying more flow. A camera inspection helps tell which.
Should older Aurora homes have their sewer lines inspected?
Many owners do, especially before buying or after repeated slow drains.
Can roots be removed for good?
Cleaning removes them for a while. Lining or replacing the pipe seals the openings so they cannot return.
Is a basement backup covered by insurance?
Usually only when a sewer backup endorsement was added, so read your policy before the cleanup starts.
What happens when I call this number?
Your call connects to an independent licensed plumber and you speak directly. We do not collect your details or call you back.
