Houses and pipes in Aurora
Original Aurora, the neighborhoods north and south of East Colfax near the old Fitzsimons Army Hospital, has homes from the 1920s through the 1950s, many small brick ranches and bungalows with clay or cast iron laterals.
Most of central Aurora, including Hoffman Heights, Del Mar and the areas around Buckley, was built from the 1950s through the 1970s, usually with basements and clay or cast iron laterals.
Southeast Aurora, along E-470 and toward Saddle Rock and Southlands, and the far northeast near DIA were built from the 1980s onward with PVC drains, finished basements and often sewage ejector pumps.
Much of Aurora sits on bentonite-rich expansive clay that swells when wet and shrinks when dry, heaving basement floors and shifting laterals.
The Anschutz Medical Campus at the former Fitzsimons, Buckley Space Force Base and a large immigrant community have made Aurora one of the most diverse cities in Colorado.
Who handles what in Aurora
Aurora Water provides sewer service across most of the city, with treatment through its own plants and Metro Water Recovery. The homeowner maintains the service line from the house to the main.
Drain problems Aurora homes see most
| Problem | Why it happens here |
|---|---|
| Shifted laterals from swelling clay | Expansive soil across much of the city |
| Roots in clay pipe | Postwar neighborhoods with mature trees |
| Basement floor drain backups | Homes with lower levels |
| Ejector pump failures | Newer homes with below-grade bathrooms |
| Grease and wipes | Large family households |
| Frozen lines | Winter cold snaps on the plains |
Aurora drains through the year
Spring snowmelt and summer storms soak the clay, swelling it against foundations and laterals. Roots grow fastest in early summer.
Winter arctic fronts sweep across the plains and can freeze drains in garages, crawlspaces and exterior walls.
What drain cleaning costs in Aurora
| Job | Typical range |
|---|---|
| Sink, tub or toilet cleared | $140–$290 |
| Main line cleared from a cleanout | $210–$465 |
| Root cutting | $280–$620 |
| Hydro jetting | $360–$850 |
| Sewer scope inspection | $145–$290 |
| Ejector pump service | $250–$600 |
Southeast Aurora homes with PVC clear quickly. Clay laterals full of roots, lines shifted by expansive soil and ejector pump work take longer.
Before the plumber arrives
- 1
Hold off on water
Pause laundry, showers and dishes.
- 2
Basement first?
If water is rising at the basement floor drain, the main is involved.
- 3
Pump alarm?
If a basement bathroom has an ejector pump and its alarm is sounding, stop using water downstairs.
- 4
Find the cleanout
Usually in the basement mechanical room or outside near the foundation.
Original Aurora and Colfax
The neighborhoods along East Colfax, near the old Fitzsimons hospital grounds, are Aurora's oldest. Small brick homes there sit on clay or cast iron laterals under mature elms and cottonwoods. Roots, offsets and corrosion are common. Many of these homes now house families from around the world, often with more people under one roof than the original builders imagined.
Postwar ranches
Hoffman Heights, built in the early 1950s as one of the first big postwar subdivisions in the Denver area, and the neighborhoods that followed across central Aurora have brick ranches with full basements. Their clay laterals are now seventy years old. Trees planted with the homes have grown large, and the swelling clay has shifted many joints. A sewer scope from the basement cleanout shows the condition.
Expansive soil
Aurora is known among builders for bentonite clay, which can swell to many times its dry volume when it gets wet. Basements heave, slabs crack and laterals shift. That movement separates joints and creates bellies where debris collects. Newer homes often have structural floors and flexible connections to reduce the damage, but older homes don't.
Basements and ejector pumps
Nearly every Aurora home has a basement. In newer homes with a basement bathroom below the main, an ejector pump lifts waste up to the line. Pumps wear out, floats stick and power outages stop them. Test the alarm a couple of times a year and keep wipes out of basement toilets, since they jam the pump.
A typical Aurora call
In June, after a week of afternoon storms, a family in a 1962 ranch in Del Mar finds water seeping from the basement floor drain. The plumber clears the main from the basement cleanout, cutting roots from a silver maple about thirty-five feet out, then runs a camera that shows a joint separated by soil movement. The family schedules a spot repair.
Southeast Aurora
Saddle Rock, Tallyn's Reach, Southlands, Murphy Creek and the newer neighborhoods along E-470 were built from the 1990s onward with PVC drains, finished basements and, in many homes, an ejector pump serving a basement bathroom. The pipe rarely fails. Calls there are mostly about kitchen grease, wipes in kids' bathrooms and ejector pumps that jam on wipes or wear out after fifteen years. Newer neighborhoods near DIA and Green Valley Ranch see first-year construction debris too.
Winter on the plains
Aurora sits on open high plains with nothing to slow an arctic front, and winter wind can drive temperatures well below zero. Drains and supply lines in garages, crawlspaces and along exterior basement walls freeze first, and shallow laterals under driveways can freeze in a long cold spell. Wrapping exposed pipe, keeping garage doors shut and letting a faucet drip during the coldest nights prevent most frozen lines.
Restaurants on Havana and Colfax
Havana Street and East Colfax are lined with restaurants serving food from Korea, Ethiopia, Mexico, Vietnam and beyond. Commercial kitchens frying, braising and grilling all day need interceptors pumped on a short schedule and lines jetted every few months.
Buying in Aurora
Sewer scopes are standard in Denver-area home sales, and in Aurora they often show roots in postwar clay laterals or joints shifted by expansive soil. Watch the video yourself, not just the summary, and get a repair quote before closing.
What to tell an Aurora plumber
Give your neighborhood and the home's age, whether there's a basement bathroom or ejector pump and whether water came up through the floor drain. Mention big trees and whether the trouble started after rain or snowmelt, and whether more than one family lives in the home.

Aurora drain questions
Who handles sewer in Aurora?+
Aurora Water. The service line from the house to the main belongs to the homeowner.
Can expansive soil break my sewer line?+
Yes. Clay that swells and shrinks can shift laterals, separate joints and crack pipe. A camera inspection shows the damage.
What is an ejector pump?+
It's a pump that lifts sewage from a basement bathroom up to the main line when the fixtures sit below the sewer. If it fails, the basement can back up.
Should I get a sewer scope before buying?+
Yes. It's standard in the Denver area and catches roots, offsets and bellies.
