NOTICE UPDATE August 11, 2022:   Environmental Services will continue to flush hydrants in Grande Cache on Monday, August 15 and Tuesday, August 16, 2002. The locations will be Industrial and Phase 1.  We will be making our way through all the phases over the next couple of weeks.

Hydrant flushing is the quick release of water from fire hydrants—a controlled procedure that is vital to the general maintenance of our water distribution system. It ensures adequate water flow is available to residents and businesses—as well as to our firefighters during major firefighting efforts. It also helps maintain our water clarity and quality by clearing iron and mineral deposits from the water mains (distribution pipes).

Sometimes hydrant flushing can make the water temporarily appear rust-colored because the iron and mineral deposits in the water get stirred up. This cloudy or tinted water is still safe to use and consume during hydrant flushing, but it may stain laundry. Please flush/run your taps after the hydrant flushing has subsided in your area to help wash away any residual particles that may have entered your water line.

For more information, please contact Environmental Services at 1.825.347.2108.

NOTICE: Please be advised that contracted sewer flushing and camera work will begin in Zone 1 in Grande Cache, beginning Monday, August 8, 2022.  Zone 2 is tentatively scheduled for Friday, August 12, 2022.

Residents may notice a sewer smell after your street is cleaned. This could be due to the P trap in your basement having no water in it.  If you notice a smell, please take a glass of water and fill the trap or traps so that gases stop coming into your home. This smell can happen when cleaning, depending on how your home’s plumbing was done, or if there is a blockage in your venting stack preventing air movement.

Regular updates as the work progresses will be available on our website at and on our Grande Cache, MD of Greenview Facebook page.

  • Sewer main cleaning helps prevent blockages and backups by removing build-up in the mains including tree roots, grease, grit, and sand. This important maintenance work keeps our sewer mains flowing, reduces the potential for nuisance odours and helps protect our infrastructure.
  • Sewer main cleaning is also done for CCTV inspection work. These inspections allow us to see the condition of our sewer mains and make necessary repairs or replacements.


You can help prevent blowbacks and odours in your home by:

  • Occasionally adding water to sinks and floor drains to prevent sewer gases from entering your home.
  • Checking your plumbing vents each spring and fall for blockages (e.g., bird nests or leaves).
