Week of June 8 to June 12, 2020

The City’s annual watermain flushing program will start Monday April 27, 2020 and will continue until late July. We are advising residents that in 2020, there may be more discolouration in your water than in previous years.

Each Friday, the maps below will be updated to indicate where crews will be undertaking watermain flushing. Should your area be highlighted below, you may notice a slight discolouration and reduction in water pressure while crews are flushing in your immediate area (Monday to Friday, 8 am to 8 pm).  Your water service should not be interrupted.  If you have no water pressure, please contact Public Works Dispatch at 506-859-2643 as soon as possible.

How will I be affected?

Flushing is generally conducted Monday to Friday between 8 am and  8 pm. While the hydrants are being flushed, customers in the immediate area of the flushing may experience discoloured water or a small drop in water pressure but water service should not be interrupted. We recommend avoiding doing loads of white laundry on these days between 8 am and 8 pm. We recommend checking around your neighbourhood for water in the roadway to see if crews are in your immediate area. Out of an abundance of caution, we recommend waiting until the following day to do laundry to avoid any discolouration. In the event that you have no water pressure, please notify Public Works 24/7 dispatch line at 859-2643 as soon as possible.

Why is the 2020 flushing different than previous years?

This year, residents may experience additional discolouration in their water when flushing is taking place in their immediate area. This is due to the Water Transmission Main Assessment program that was carried out last fall. This assessment program disturbed the manganese deposits within the large diameter pipes which was eventually spread throughout the City. It is expected that the manganese has settled and may be flushed out during this year’s program.  Manganese is a naturally occurring mineral and is not harmful. It may be noticed as small black specs in the water. Other than discolouration, residents may experience slight changes in water pressure while the water is being flushed. Your water service should not be interrupted.

Why do we flush pipes and Fire Hydrants?

Flushing of pipes and fire hydrants is required to maintain water quality. The scouring effect of high velocity water helps to clean the interior of the pipes, flushing the accumulated sediments out of the system, removing stale water, and restoring chlorine residual. The City has an annual flushing program, which is carried out in the spring when there is extra water available.

Why are we flushing?

Since water mains are sized to allow adequate and safe flows for fire protection, water typically is moving through the underground pipes at less than 1 km/hr. This slow movement allows mineral deposits to accumulate in pipes over time. The build-up can restrict water flow in the pipes and contributes to corrosion and water colour problems. Periodic flushing removes the mineral deposits and is critical to maintaining water quality and the water system.

Why is the City flushing pipes during the COVID-19 pandemic?

City crews and contractors have taken additional precautions to ensure that they are practicing social distancing and wearing appropriate gear as recommended by Public Health officials. Water distribution/administration and water quality and treatment are among the services deemed essential for the City of Moncton. We recognize that residents are home more than usual and given the additional work completed in 2019 that may result in additional discolouration, we have taken additional steps to ensure that residents are informed throughout the process.

Flushing Progress & Updates

The City will have three crews in three different locations each week throughout the City. Each week, the map will be updated to advise residents if crews will be in their area the following week. Highlighted areas are scheduled to be flushed. Updates will be made on this webpage as well as via the City of Moncton’s social media channels.

What if my water is discoloured?

Should black or brown coloured water appear, do not be alarmed. It is recommended you do not use the water or do laundry.  Run your faucets for a few minutes to make sure the water is clear and then resume normal water use. If water does not clear within a few hours or you have lost all water pressure, please notify our 24/7g Public Works Dispatch Line at 859-2643.
