If your Portland street is selected for water-main replacement, expect advance project information, a work zone and possible planned water interruptions. Save the notice and check its address-specific instructions before arranging plumbing work. A street project alone does not establish that the pipe supplying your home needs replacement.
The Portland Water Bureau's October 13, 2026 program update says its crews have 64 main-replacement projects planned for fiscal year 2026-27. That count is a city program total. It does not identify your home's construction date or repair needs.
First, confirm which project and water provider serve you
A Portland mailing address is not enough to identify the work. Read the notice for the utility, project name, affected streets and contact details. If the notice is from another water district, use that district's instructions. Keep the notice where everyone in the household can find it.
For a Portland Water Bureau project, ask its construction outreach team at 503-823-0102 whether your block is included, what access will be affected and how updates will arrive. The city's construction guide is the general reference; the notice supplies the details for your street. For the separately named Southwest Portland project, see our Fulton Pump water-service guide.
A covered trench can still have work left
Portland's standard sequence includes excavation, pipe installation, sanitizing and testing, then a notified connection to the water system. Permanent paving follows. A steel plate or temporary patch can cover a trench while later steps remain.
Keep access clear and stay outside the work zone.
Check updates. A covered trench does not tell you the connection date.
Follow the shutoff notice and later restoration instructions.
Before a planned interruption, choose a time for laundry and other water-dependent tasks outside the stated window. Ask the project team about essential water needs rather than assuming the advertised end time is guaranteed. If plans change, pass the update to anyone who shares the property.
Know where city maintenance ends
For domestic and irrigation connections one inch or smaller, Portland Code 21.30.130 assigns maintenance from the main through the meter to the meter stop to the Water Bureau. The owner maintains the portion beyond the meter stop to the right-of-way and on private property. Larger connections and fire services have different boundaries.

The code also allows the bureau, with owner permission, to work on the owner's side as needed to reconnect an existing line during a city project. Ask which segment is included before hiring someone for an overlapping job. A new street main and a whole-house repipe are separate scopes.
For a private-side investigation, ask the plumber to identify the affected segment and explain what the estimate covers. Our water-line repair guide explains that service; confirm coverage for the address with the team. Keep any city project response with your notes.
Report unexpected water loss before guessing at the cause
Portland's water-service problem page specifically lists sudden loss of water during nearby construction without notice. Call the Water Bureau's 24-hour emergency line at 503-823-4874. The same line handles water leaking or gushing in the street.
Tell the operator when the problem began, which fixtures are affected and whether you received a notice. Those observations help describe the problem; they do not prove that a crew damaged your service line. Record the response before deciding on a private repair visit.
If the water changes color after work
Construction can stir up sediment in water mains. Portland's discolored-water guidance says to report the problem, check one cold faucet for one to two minutes each hour and turn it off if the color remains. Avoid running water continuously, limit hot-water use and postpone light-colored laundry. Consider bottled or stored water for drinking and cooking.
Once the cold water clears, the bureau advises running all cold taps for a minute or two and checking aerator screens for sediment. For quality or pressure questions, its Water Quality Line is 503-823-7525, Monday through Friday, 8:30 a.m. to 4:30 p.m. Follow any active notice that applies to your address.
Questions about a Portland main replacement
Does the 64-project announcement mean my street is on the list?
No. The October 13 announcement describes the program, rather than an address-specific schedule. Ask the Water Bureau project team whether your street is included and when work is expected.
Will I have water throughout construction?
Planned interruptions can occur. Portland says it provides at least 24 hours of advance notice for a planned service disruption. Use the notice for the timing at your address; report an unexpected loss of water to 503-823-4874.
Does the city replace the pipe all the way into my house?
Confirm the project scope. For domestic and irrigation connections one inch or smaller, Portland code places the maintenance boundary at the meter stop. A city project may reconnect an existing private line with owner permission.
Should brown water after construction run continuously until it clears?
No. Portland advises checking one cold faucet for one to two minutes each hour, then turning it off if the color remains. Limit hot-water use and follow the utility instructions for your address.
For a private plumbing concern, contact True Plumbing with your address, symptoms and the utility's response to confirm coverage and the next step. The service-area guide can help you prepare that call.
