Water Main Flushing Program

The City of Fredericton’s annual water main flushing program begins on Monday, May 25, and is expected to continue until the week of July 27.

This year’s flushing includes a portion of the Southside (low system) and the entire Northside system.

Most flushing occurs during daylight hours, from 8 a.m. to 8 p.m., except for the downtown core where flushing happens at night, so traffic and pedestrians are not inconvenienced.

The following dates and times only apply to the downtown core, after that the regular daylight hours occur: 

  • May 25 & 26: 9:00 p.m. to 7:00 a.m.
  • May 27 & 28: 9:00 p.m. to 9:00 a.m.

Updated areas that will be flushed the week of May 25 to 28

Northside:

  • Areas bounded by: Not applicable

Southside: 

  • May 25 & 26: 9:00 p.m. to 7:00 a.m. 
    • Areas bounded by: ​Queen Street and King Street from Smythe to Waterloo Row 
  • May 27 & 28: 9:00 p.m. to 9:00 a.m.
    • Areas bounded by: ​Brunswick Street and Beaverbrook Street from Smythe Street to Waterloo Row.

Water flushing may produce discoloured (turbid) water, and residents should check for clear running water from their taps before doing laundry or preparing food. The effect is temporary and should clear up quickly. If the issue persists, contact Service Fredericton at 506-460-2020 or service@fredericton.ca.


Water main flushing removes loose sediment and mineral deposits from the water distribution system. It is a cost-effective preventative maintenance measure, and part of the process to ensure continued high-quality drinking water in Fredericton. It also helps identify areas of the water distribution system that might need repairs and upgrades.
