Water Concerns

We follow a Multiple Barrier Approach to water quality to ensure your water is safe and clean

Halifax Water operates three large state-of-the-art, ISO 14001 Certified, water supply plants and six modern smaller community supply plants to provide water to 360,000 customers throughout the Halifax Municipality.

Operators at all Halifax Water’s supply plants continuously monitor and adjust the treatment process to ensure the water output is of the highest possible quality.

Discoloured Water

Naturally occurring minerals (primarily iron and manganese) in the water are typically to blame for water discolouration. These minerals, which are heavier than water, settle in water mains under normal operating conditions.

Basement Flooding & Sewer Backup

Sewer/wastewater backups can be caused by severe flooding or by a plugged wastewater connection. Over time, tree roots, grease or other debris can build up in the connection eventually causing a blockage. Here is some helpful information for preventing or dealing with backups.

Water Treatment - Chlorine & Fluoride

Each water supply plant has varying types of treatment systems in place based on the source water quality. The varying treatments conducted at the plants include:

  • Direct dual-media filtration
  • Sedimentation with multi-media filtration
  • Direct filtration
  • Disinfection (ultraviolet and sodium hypochlorite)
  • Ultra filtration
  • Nanofiltration
  • Iron and manganese removal/green sand filtration

Household Mould

Black Mould

  • often found in the corners of showers and tubs where caulking and the tub meet, in tile and grout, around the rim of toilets, at the base of bathroom faucets, in dishwashing and laundry machines rubber seals, and the base of shower curtains.

Pink Staining

  • found where air and water meet: shower curtains or doors, the water lines in toilet bowls, drains, tile and grout, and pet’s water dishes. While pink staining is often pink, it can also be orange or red.

Black Biofilms

  • found in toilets tanks, at the waterline in toilet bowls, the rim of toilets, the inside of bathroom and kitchen faucets, and drains. Biofilms grow in warm wet environments where there is a food source such as soap scum, toothpaste, and/or bacteria.

The most effective way to remove mould is by frequently cleaning with a chlorine bleach-based cleaner combined with thorough heavy-duty scrubbing. Chlorine bleach based cleaners (for example Lysol, Old Dutch, Comet) will use wording such as “Disinfect” and have “Sodium hypochlorite” or “hypochlorite” listed in the ingredient list.

“Spray and Walk Away” cleaners do not remove the problem as they are sprayed on top of existing dirt. Additionally, eco-friendly or “green” cleaners do not kill the mould and are more likely to only remove dirt noticeable to the naked eye.
