Is the City replacing sewer lines in downtown Greeley?

The City is replacing its sewer mains, not your private line. Its Downtown Infrastructure Improvements Project swaps out aging water, sewer and stormwater pipes under nearly 20 blocks. The service line from your house or business to the main is still yours to maintain, even after a new main goes in.

Downtown Greeley street work: the City main versus your sewer lineCross-section of an older downtown Greeley home and street. The City is replacing its aging sewer main under the street as part of the Downtown Infrastructure Improvements Project. The homeowner’s service line runs from the house, past the cleanout and under the sidewalk to the main, and it stays the owner’s to maintain. A backup during nearby street work should be reported to the City first; a backup in only one home usually points to the private line.Older homeCleanoutSidewalkStreet workNew City sewer mainYour service line: house to mainCity work: 2026 to 2028City main: newThe City is replacing its oldmains under downtown streets.Your line: still yoursThe pipe from your house tothe main stays yours to fix.Backup during work?Tell the City first.

A new main under the street does not fix an old, cracked or root-filled line on your side. If your drains act up, a camera check of your own line shows what’s going on. For the full ownership rules, see who owns the sewer line in Greeley.

What the downtown project covers

The City of Greeley started the project in summer 2026 and is building it in phases through 2028. It says much of the infrastructure beneath downtown is more than 100 years old. The work replaces mains first, then improves roads, sidewalks and lighting.

  • Nearly 20 blocks The work covers the historic downtown core. The first phase was on 7th Avenue between 9th and 10th Streets, with a new waterline and sanitary sewer.
  • About 2.25 miles of mains New water, sewer and non-potable water mains, plus about 1 mile of stormwater pipe and 1.3 miles of large stormwater culverts.
  • Built in phases By mid-October 2026, crews had laid about 1,700 feet of sewer pipe, close to half the new sewer pipe planned for downtown.

The City says businesses and sidewalks stay open during the work, though streets and intersections close for stretches at a time. Recent work has included 9th Avenue and 10th Street. For closures and detours, check the City’s project page on Speak Up Greeley.

Who do I call if sewage backs up during downtown construction?

If crews are working on your block, or neighbors and the shop next door back up too, tell the City first so it can check its main. If only your home or business backs up, the problem is most likely in your own line, so call a private sewer pro.

  • 1 Stop running water, flushing and laundry so the backup doesn’t get worse.
  • 2 Look around. Are crews digging nearby? Is anyone else on the block backing up?
  • 3 If yes, report it to the City right away.
  • 4 If it’s only your building, call us for a sewer pro. A camera check finds the spot.

More help: emergency sewer repair, basement floor drain backing up and what insurance may cover.

Do old downtown Greeley homes need sewer line replacement?

Not always. An old house doesn’t mean the whole line has to go. Many older lines have one bad joint, a root spot or a low section that can be fixed alone. A camera check shows the real condition before anyone talks about full replacement.

  • Downtown and East Greeley Known for historic bungalows and Victorian homes from the early 1900s.
  • Maplewood The nearby Maplewood area runs more toward brick ranch homes from the 1950s.
  • Central and north Greeley The area around Banner North Colorado Medical Center is older and well established.

The line under an older home may have been patched or partly replaced over the years, so its age doesn’t tell you what’s down there. That’s true across downtown and central Greeley, so we start with a sewer camera inspection. Then you’ll know if it’s a spot repair, a full sewer line replacement or just a cleaning.

Signs worth a camera check: several slow drains at once, gurgling toilets, sewer smell in the basement or a backup in the lowest drain.

Can you do trenchless sewer repair under downtown streets?

Often, yes. Trenchless methods fix many lines through a cleanout or small pits instead of a long trench. That matters downtown, where lots are narrow, driveways are shared and the line may run under a sidewalk, mature trees or an alley.

  • Pipe lining A new pipe is formed inside the old one, sealing cracks and joints.
  • Pipe bursting New pipe is pulled through as the old one is broken apart, pit to pit.
  • Small dig For one bad section, a short pit at that spot can save the rest.

A camera check shows whether your line is a good fit. A badly sagging or collapsed section may still need digging. Sewer line replacement in Greeley needs a permit, and the work is inspected before the trench is filled. Your contractor should handle the permit. Learn more about trenchless sewer repair and sewer repair costs.

Downtown businesses and buildings with more than one unit

A shop, restaurant or office downtown can’t wait on a backup. The same rule applies: the City handles its main, and the owner handles the line from the building to the main. In some older buildings, more than one unit drains through one line, so a camera check shows how yours is set up.

Knowing the layout first helps everyone sort out who needs to fix what before the bill comes. Downtown Greeley has a long history: its historic downtown district is on the National Register of Historic Places, and business there grew from about 1880. A careful repair plan protects older buildings and storefronts.

Buying an older home near downtown?

A sewer scope before closing can show roots, cracks or a sag while you can still ask for a repair or a credit. See our guide to a sewer scope before buying a home in Greeley.
